How to choose a Better Battery for Laptops

Boston-Power says that it’s poised to enter the market for portable power, with a laptop battery the company claims is safer, lasts longer, and can be charged faster. The Westborough, MA, startup recently announced that it is more than tripling production of its high-performance battery, called the Sonata, after receiving $45 million in a third round of venture financing. The move puts the company in a position to mass-produce and commercialize its next-generation lithium-ion battery news and battery blog within months.

“In partnership with GP Batteries, one of Asia’s largest battery manufacturers, we now have our second factory up and running in the greater China region,” says Christina Lampe-Onnerud, the company’s founder and CEO. In 2002, Technology Review named Lampe-Onnerud one of its top innovators under the age of 35 for her efforts to develop vgp-bps9 , VGP-AC19V13 better-performing lithium-ion batteries with less volatile substances. Based on that research, she founded Boston-Power in 2005. Now, after raising $68 million in total, she says that her company will be able to manufacture a million battery cells per month by the end of 2008.

Oak Investment Partners, based in Westport, CT, provided this latest infusion of capital, building upon earlier investments by Venrock Associates, Granite Global Ventures, and Gabriel Venture Partners.

Although the Sonata will not offer lifebook t4010 battery greater energy capacity per use–with a four-hour run time, its performance will be average for the market–the company hopes that the battery’s three-year life span, innovative safeguards, and ability to recharge quickly will help it gain a foothold in the battery market. As opposed to existing notebook batteries, which can take an hour to recharge to 80 percent capacity, the Sonata can reach that same level in just 30 minutes, according to Boston-Power. And whereas current batteries degrade very quickly, permanently losing up to 50 percent of their capacity within months, the Sonata retains up to 80 percent of its capacity over three years. In fact, since the typical laptop battery tends to degrade very rapidly, the Sonata will have a greater per-use capacity in the long run.

To make the cell retain its capacity over its lifetime, Boston-Power found it necessary to change the current lithium-ion design. The company identified a combination of new chemistry mixtures and electrode compositions, and it created a new shape–all of which enables a consistent performance over the cell’s lifetime. The different shape made it possible for the company to increase the volume of the cell and more efficiently use the space within a xps m1210 battery pack, allowing it to reach energy-storage levels competitive with current conventional batteries.

In the past, it has been very difficult to make lithium-ion cells larger, since a larger energy density creates a potential for greater catastrophic malfunctioning. Conventional lithium-ion batteries use cobalt oxides, but the substance has been partly responsible for some of the more dramatic laptop explosions in recent years. So instead of using cobalt, which also tends to degrade quickly, the company incorporated manganese. Boston-Power isn’t the only company using manganese; other companies, such as Compact Power, are also trying to take advantage of its stability. Boston-Power is incorporating the element into a larger than average cell.

The company has also made the battery safer by separating several conventional safety measures and by inventing new ones. In existing notebook batteries, the current interrupt device and the thermal fuse are packaged on top of each other in the cell’s lid. But by separating these elements from each other, the company has built an extra layer of redundancy into the system. These elements are able to control and cut off the current flow, should the kd476 , latitude d600 battery begin to overcharge. The company has also devised a new ventilation system to alleviate the pressure and heat before they build to catastrophic levels. With aluminum in its canister, rather than carbon steel or nickel, as is common, the Sonata’s shell softens much sooner at high temperatures and then self-destructs with a hiss. More-durable elements like carbon steel, which melts at even higher temperatures than aluminum, exacerbate explosions by letting extraordinary pressure and heat build inside the cell until its breaking point. (This is why conventional laptops emit loud booming cracks when they burn.)

“There is a lot of progress being made in battery technology with different chemistries,” says Robert Kanode, president and CEO of Valence Technology, an Austin, TX, startup that manufactures phosphate lithium-ion batteries. His company is a competitor with Boston-Power, but Kanode adds, “We know we will not be standing alone: this will be a huge market with many viable players in it.”

Lampe-Onnerud says that Boston-Power is in discussions with most of the world’s top-tier notebook makers, including Hewlett-Packard, which over the past two years has worked closely with the company, helping it design f4809a , inspiron 6000 battery packs that can be dropped into existing notebooks.

“The Sonata opens up a whole new business model for notebook manufacturers that hasn’t been available in the past,” says Ifty Ahmed, a general partner with Oak Investment Partners, who worked on the deal. Although notebook makers can presently offer a three-year warranty for a computer, they can’t make the same offer on a battery, a component that can cost about 10 percent of a laptop’s total value. “The market for warranties is extremely profitable,” Ahmed says. “So if you can sell a warranty on the battery for three years, you have a very exciting idea.”

Boston-Power says that it is focused on commercializing the Sonata, but it also believes that its patented safety features could eventually be used in lithium-ion batteries of inspiron 600m battery , inspiron e1705 battery which are used for smaller consumer-electronics devices as well as for hybrid electric vehicles.

Access to the notebook battery market time notebook battery market time is coming

Now more and more people use laptop computers, and the pattern book for the pattern model is also renovation and fashion of choice for owners. But laptop battery is consumables, life is only a short period of 1 ~ 2 years, once to come to an end, it is necessary to replace the battery. However notebook battery price is more expensive, at least a few hundred, as many as thousands, spent a bit of heartache. Thus, many users simply take the battery computer maintenance repair -Since you have a computer, it also should be able to fix the battery, right?

There is a saying in economics, called the market demand. As someone who brings the battery to repair, it was natural for “laptop battery maintenance.” However, in talking about “maintenance” issue, we first look at the structure of the notebook battery. Most notebook computers are used in lithium-ion batteries, which batteries group, control components, the protection of components,such as dell GD761 ,KD476 , VGP-BPS2C , F4809A , the battery interface and shell, of which batteries group is the core of the whole cell, usually from a few root columnar batteries and a multi-string forms of hybrid battery pack together to form; and control the management of battery components, battery charge and discharge control and battery status of the issue of compatibility. Protection of components in the battery temperature is too high or too large, such as current cases cut off the line between the battery contact with the outside world. Several components of the above, batteries are the most critical part of the material properties of lithium batteries determine its useful life of only 1-2 years, so when the laptop battery problems, the majority of cases there is the capacity of batteries and the attenuation increases with the resistance led to a serious shortage of working hours.

In various parts of the electronics market, all kinds of “battery maintenance” overwhelming. Second-hand laptop with a random counter, can be cheaper to buy the batteries, both second-hand goods open original, but also replaced the batteries and counterfeit goods. From the description in the sales of these batteries cost-effective very high, and the risk is almost non-existent. In fact the contrary, the product after-sales service, according to IBM officials said privately, “for the core,” there is a big security risk, some testing batteries news without charge even after the bursting of short-circuit phenomenon, ranging from damage to the host, re – the explosion occurred. He said that in addition to insecurity, to provide for the level of core business services and maintenance of uneven quality. However, because of their very attractive price, would not prevent its circulation in the market and home consumers.

When a user with a laptop battery to be repaired, the maintenance staff to do, basically the “core for surgery.” Some unscrupulous sellers claim that the battery “back to Factory for maintenance”, but in reality its own “for the core.” The service center does not provide formal repair. Recycling of batteries will be treated there is no “maintenance ” one said. Also some black battery maintenance business, in order to reap huge profits, take the quality of the best times to serve as a good battery of the battery, more battery management components inside the control chip removed, only one wire connected to, or to have been scrapped on the circuit board inside the rechargeable battery,dell inspiron 1501 battery ,inspiron 6400 battery , the number of chips that do not control the problem can not think of immune cells.

Currently in the market a number of compatible batteries, due to the lack of industry specifications, the good and the bad battery. Some of the quality of a good brand compatible batteries, there are many low-quality crude work-compatible batteries. An interview with reporters on the issue of domestic brand laptop battery “E to the notebook battery,” the person in charge. He said that there do exist a number of individual traders, “TM” to deceive the consumer situation. According to the said individual traders in general very few channels to purchase good quality batteries, more removed from other cells, or barely processed products can be refurbished. Batteries such as poor security, performance, significantly lower than the normal standard. And “E to” brand batteries imported and domestic brands of genuine large-scale batteries for more than ten years to provide world-renowned products and services, is rich in battery R & D, production experience. Quality no less favorable than the original laptop battery , perfect after-sales service system.

The person in charge at the same time also to remind consumers, at the time of purchase must be OK to see the second three questions: to see the battery parameters; battery weight; asked about the battery after-sales service. Some poor-quality printing on the outer cell illegible, the battery shell rough comparison, interface work is also far from satisfactory, so that the quality of the products it is difficult to guarantee, not to mention the after-sales service. Therefore, beloved for his book to buy batteries, consumers tens of millions of caution.

About Battery Status Icon Missing on IBM Laptop

The battery status icon on an IBM ThinkPad laptop is one of the most useful icons on the desktop. By having this utility installed on your computer, it is easy to tell at a glance how much lenovo battery power is left and how soon you need to change batteries or recharge. Most ThinkPad’s come with the battery status utility and icon already installed, but on a used computer, this may not be the case, and you will need to install the utility yourself.

Significance

Depending on the model, the battery blog and battery news status icon, either at a glance or by a mouse click, will tell you exactly how much battery life is left. This is useful when using the laptop away from an alternative power source so that you can save your work and close down before the battery is completely depleted.

Features

Since many IBM laptop models allow for the use of two batteries, the battery status icon can track the charge usage in both lenovo batteries. The battery status utility will recognize both batteries on the startup of the machine, the icon will alert the user when battery power is low and then again when the power is at a critical level.

Considerations

Clicking on the icon will allow the user to change the way the computer operates when running completely on battery in order to save power. This will allow the user to turn off devices that will not be used while on battery power, such as DVD players or modems, or tell the system when to go into standby or hibernation mode if the computer is idle.

Benefits

By enabling the thinkppad t60 battery status icon on the desktop, the user is always aware of the approximate amount of computing time that remains before the battery is depleted. This allows the time needed to save the work being done or attach the machine to an alternative power source such as a car adapter or regular electric current.

Prevention/Solution

If the battery status icon is missing from the IBM laptop, the first step is to discover if the machine has the configuration utility program installed. If the program is there, it is a simple matter to run the program and enable the icon on the desktop. If the ThinkPad is missing the configuration utility, make a note of the model and serial numbers of the machine and go online to the Lenovo website (see Resources below). Type the model number into the search box and the returning results should display the lenovo thinkpad t60p battery status utility. Download the program and install it on the ThinkPad.

Potential

The battery status utility available for some models of the IBM ThinkPad will also allow the user to check on battery health. This will give statistics on how many times the battery has been recharged and how much remaining life is left in the battery. This program is useful in determining when a new battery needs to be purchased.

Lead-acid battery industry in China will show a rapid growth momentum

China Battery Industry Digital Camcorder Battery Association, vice chairman of the Jin-Liang Wang believes that rapid growth in the automobile industry, and policies on the renewable energy industry, strongly support, industrial electronics technology continues to progress, driven, China's lead-acid battery industry and the international advanced level will gradually narrow the gap, China's lead-acid battery industry will show rapid growth momentum.

According to incomplete statistics, China's lead-acid battery manufacturer, has reached around 1500, producing an average annual rate of about 20% of the rapid growth of production in total world production of lead-acid batteries for 1 / 3, plays a decisive Digital Camera Battery role in the international market position. As China's lead-acid battery to speed up technological progress, the traditional lead-acid batteries through the transformation and improvement, is moving in sealed maintenance-free batteries and other new aspects of development, at the same time by virtue of low-cost advantage, China's export of lead-acid batteries also show rapid growth momentum in recent years, export volume, exports were up 29% a year Casio Battery, and 34% of the rate of increase.

Perspective on staff Matsushita Battery cadmium poisoning is epidemic

Recently, sustained more than four months of Wuxi Matsushita Battery cadmium poisoning employees finally have the latest developments: Wuxi Matsushita has been active in the May 10 notice "cadmium exceeded targets" by staff, will refer the case of cadmium poisoning in Guangdong Huizhou standard deal with the aftermath . This makes a lot of Chinese people feel happy.

Speaking of Panasonic Battery Corporation of Staff cadmium Casio NP-100, Casio NP-20 poisoning incident, we will not help with the "child of Hon Hai workers" on the foreign press events as well as other incidents linked to the Chinese employees with foreign-funded enterprises become the main object of criticism. May I say that, attacking foreign employer who might as well make plans for education reform more.

A common problem

Child labor, excessive overtime, not only in phenomena such as Panasonic, Hon Hai and other foreign-funded enterprises in the existence of many manufacturing enterprises in China are also common.

I have visited a number of household electrical appliance enterprises in China Casio NP-30, Casio NP-40, Casio NP-L7 and witnessed the plight of these enterprises front-line employees. In a well-known home appliance business, operatives are generally called "outsourcing jobs" These employees do not sign labor contracts with the home appliance business, but rather entered into a contract with the intermediary, intermediary institutions and household electrical appliance enterprises entered into employment contracts. The contract provided that these employees of death and so on, by the intermediary responsible for their own not responsible for the household electrical appliance enterprises. Of course, each of these appliances will allow some companies "outsourcing jobs" regularized, the signing of "peasant-workers labor contracts."

According to the author learned that these "outsourcing jobs" average age of less than 20 years of age, they are mostly junior high school graduates or graduates of rural children do not. However, they did not stay in school, but wearing a uniform covered with oil on the work in the manufacturing line. And they suffer from "9-9 working day" in press, which means 9:00 to 9 pm, continuous 12-hour working time.

If the foreign staff of the Chinese press and exploitation, then some DSLR Battery Grip Chinese companies because there is no contract, squeezing and exploitation. Therefore, foreign workers abuse incident, but China's current manufacturing enterprises is a common situation, not a special case.

"Bonded labor" Why there

"Bonded labor" has been a common problem is the manufacturer, then the root cause of the problem what is it? Some people say this is because the employer's greed, the employer's immoral, but I think this is a fallacy.

In China, India, Pakistan and other developing countries, parents send their children to under-age workers to families in order to generate income. According to the author learned that many children in rural areas did not finish junior high school were sent to cities to work, make money Canon BG-E2N Battery Grip for the brothers and sisters to school. Although parents can be aware of the importance of schooling, but the demand for labor in large cities, income farming at home is better than many, and the media of college students difficulty in finding employment, which have all been abandoned rural parents to keep kids in school.

Matsushita battery plant employees to take regular example, they usually can be a monthly income of 1,700 yuan, the wage level has not been low, and the income derived from the plain areas of 8 acres of land full year net income probably much higher. And many factories have to take the piece Pay Act, in order to offer more income, the workers are willing to work overtime, many companies are not forced to.

Therefore, in essence, resulting in manufacturing companies employing child labor, overtime is mainly due to higher short-term economic interests of the parents and children of conflict between the interests of long-term economic results, rather than the greed of employers with no humanity. As a developing country, a large number of foreign investment is China's GDP growth rate in one of the major high; the other hand, foreign-invested enterprises in China are also digesting a large number of generated due Canon BG-E3 Battery Grip to increased mechanization of rural surplus labor.

Attacked more than greedy business owners make plans for education

Although child labor, overtime, child workers and employers the occurrence of events such as the greed is not necessarily linked, but this is, after all, led to many Chinese workers were injured. For example, cadmium poisoning, employees and suffer the pain of the household electrical appliance enterprises overtime "outsourcing jobs", they suffer physical and mental suffering. But we can not be foreign-funded enterprises and Chinese manufacturers are sealed, then the solution to this problem there?

I believe that, first and foremost the education subsidy system, followed by the Canon BG-E5 Battery Grip reform of education system.

Of a country's economic success in terms of education as an investment in human capital and physical capital investment are equally important. From the United States history, formal education each year makes the average wage increase of about 10%; while in developing countries with scarce human resources educated and uneducated workers and employees a greater income gap.

But in China, a large number of university graduates can not find jobs, rather than go to school you can work to earn money, which leads to useless parents that their children go to school. I can take into account the children go to school can give to finance, for example, to a certain amount each Canon BG-E6 Battery Grip month for living expenses, so that those who abandon their studies to the working children back to school; Secondly, the combination of increased production and research for the society to cultivate useful talent, rather than a four-year college students are now squatting in schools mediocrity.

If China can not allow more children to receive higher education, which would lead to economic inequalities between developed countries, permanent, because there is no formal education of the children to learn their parents are poor, this is a vicious circle. Therefore, I believe that criticized the greedy Canon EOS 20D Battery Grip business owners who might as well make plans more reform in China.

MII: June 14 starting a new network interface mobile phone chargers should be uniform

According to the Guangzhou Daily reported Digital Camcorder Battery yesterday, Ministry of Information Industry issued a circular calling for since June 14, 2007 at the mobile phone Jinwangjiance to start implementation of a uniform interface standard. By then, all produced in China a new application into the mobile phone network license and matching chargers have to be a unified interface. It is understood that so far, including Nokia, Motorola, Sony Ericsson and other foreign brands as well as some domestic mobile phone handset makers have not yet come to participate in the standard, but because the standards are not mandatory standards, consumers buy these brands may be temporarily unable Enjoy a unified interface to bring the convenience of mobile phone charger.

In order to unify mobile phone charger Digital Camera Battery interface, Ministry of Information Industry issued in December last year, "Mobile Communications Handset Charger and Interface Technology Requirements and test methods." Yesterday, the Ministry of Information Industry issued a notice to accelerate the implementation of mobile phone charger and interface uniform technical standards. "Notice" requirement since June 14, 2007 at the mobile phone Jinwangjiance to start implementation of the new cell phone charger interface standard. By then, all produced in China a new application into the mobile phone network license and matching charger shall comply with relevant regulations. Meanwhile, in order to encourage producers to implement the standard as quickly as possible, for June 14 in accordance with the standard application into the network, mobile phones, Ministry of Information Industry will Jinwangjiance Canon Battery, network access approval, and other links to be given priority.

It is understood that there are a number of domestic mobile phone vendors have aggressively participated in the standards. But including Nokia, Motorola, Sony Ericsson and other handset makers were not well-known international brands to participate in the standard to.

Because of this non-mandatory standards, and therefore can be predicted that in China after the June 14 production of the new network within the foreign brands mobile phone charger, or "each singing its own tune," to buy foreign brands of consumer mobile phones will be temporarily unable Canon BP-208 to enjoy Unified After the charger interface brings the convenience to buy foreign brands mobile phones have to spend more money for the purchase of chargers.

The use of nano-coaxial cable technology, America developed a high-performance solar cells

U.S. National Renewable Energy Laboratory (NREL) recently announced that they used nano-coaxial technology developed to significantly improve the performance of high-performance solar cells. Experts pointed out that this is the development of high-performance solar cells made significant progress Canon BP-511, nano-coaxial cable technology will be widely used in the microelectronics field can also be used to develop nano-computers.

Traditional solar cells working principle is very simple: When light shines when the pn junction to generate electron-hole pairs generated in the pn junction near the carrier has not been complex and the arrival of space charge region, attracted by the built-in electric field, e into n areas, holes into the p zone, resulting in a surplus store n areas of electronic, p district of excess holes. They formed near the pn junction with the barrier in the opposite direction of the photo-electric field. In addition to photo-electric barrier, partially offset by the role of the electric field, but also to positively charged p zone, n negatively charged zone in the n region and p-electromotive force generated between the thin layer. However, because they had been Canon LP-E5 inspired by free electrons and holes in the same region, electron and hole behavior frequently cancel each other out, resulting in low efficiency of solar cells.

Pn junction in order to make thinner, while addressing the issue off free electrons, the researchers combined the two semiconductors form a nano-coaxial semiconductor structures. Such nano-cables can have two different ways: one of the inner core is a gallium nitride (GaN), an outer layer of gallium phosphide (GaP); another kind of the opposite. Two kinds of cables within a core diameter of about 4 nm or so.

When the photons projected onto the outer layer of nano-cable, the excitation of electronic Canon NB-1LH and semiconductor materials have taken place between the hole and the high efficiency separation of free electrons. Coaxial cable structure not only played the role of the battery, but also played the role of ordinary cable to solve the problem of electronic separation (because of nitrogen, gallium and phosphorus have different conductivity). Eventually, due to a series of complex quantum effects, and interactions took place within the core of the outer layer of the semiconductor semiconductors can accept a wider range of visible light, thus greatly improving the performance of solar electronics. In addition, the coaxial cable can be nano-microelectronic technology, especially in the future nano-computer to obtain wider application.

Lithium Battery: electric cars, "green heart" of

A few years ago, China's electric car market just got started, their impact on environmental protection and other issues has attracted wide attention. Recently, the Zhejiang Industry & Trade Group and the Professional Rebar imperial power type lithium battery manufacturers in Suzhou Star Constant co-announced that it will join forces to promote bicycle lithium into Beijing, Shanghai and other major cities, the initiative of all sectors of society work together to promote the "dilithium" power of this New environment-friendly Canon NB-2L energy development and application. Industry experts said that the electric car industry, a huge market space will soon usher in a period of rapid growth, particularly in lithium battery used in electric vehicles so that the "lithium" Train as a green light and progressive means of transport are well known, allow ordinary people the full enjoyment of both the green and convenient way to travel, but also to address the problem in China's energy and transport problems to provide a workable way of thinking.

According to reports, the original power source for electric vehicles use more lead-acid batteries, in the production and recycling process is very easy to environmental pollution. According to experts, Shanghai Electric Vehicle Directory for approval to freeze the original reason for "green" is one of the core issue. Because most lead-acid batteries used in electric cars mainly by the lead, sulfuric acid and other metal and plastic composition of the body not only cumbersome, but also its internal contains highly corrosive sulfuric acid, containing high levels of lead, inorganic salts, will be seriously polluted by indiscriminate discharge of soil and water, and generate lead-steam, air and the environment, ecological balance can easily cause Canon NB-2LH, Canon NB-3L damage.

For this reason, development of new practical and green of the motive power batteries, replace lead-acid batteries, a domestic research institutions and production enterprises endeavors. In this context, lithium-ion power battery electric cars come to the fore. Because do not contain cadmium, lead, mercury and heavy metals harmful substances like lithium batteries in the production and use of the process does not produce pollutants to protect the health of the body, battery recycling process contaminated water and soil problems are so easily solved Canon NB-4L, Canon NB-5H. Loading lithium battery powered vehicles also has many other advantages, a city an indispensable part of the transport system is very suitable for family use: First, light weight. Many consumers complain that too heavy lead-acid batteries, a battery of 20 pounds -30 pounds weight, strength weaker of the President, the elderly is difficult to carry. The lithium-ion battery is usually in the 7 pounds up and down, about 1/3-1/4 the former is about a child can also be slightly larger Eurya get up; followed by a more long-term life expectancy is 3-4 times the normal lead-acid batteries . Winter lithium batteries can be used normally in the low-temperature environment, there is no lead-acid batteries to power a significant attenuation of the winter issue. At the same time, at any time charge, no memory effect is also reflected in Canon NB-5L, Canon NB-6L superior performance of lithium batteries.

An annual output of 5MW of amorphous silicon solar cell production line will start construction

After more than two years of project laptop battery preparation and feasibility studies, an annual output of 5MW of amorphous silicon solar cell production line project has been approved by the State Planning Commission project, is stepping up construction of Tianjin. The project is scheduled in Tianjin New Technology Industrial Park Huayuan Industrial Park plant, a total investment of 198 million yuan during the year to start production next year. It was reported that solar cells as a new source of energy, has limitless nature of the power structure can be matched with conventional and non-application of restrictions on geographic characteristics, as governments develop non-polluting, sustainable development of new energy sources of choice. The solar cell implementation of the project will also promote related industries in Tianjin, such as batteries, inverters, controllers and other industries, as well as machinery, electronics, household appliances and some other industries.

Tianjin, this solar cell production line project is based Nankai fujitsu battery University, relying on the technology of photonics. Nankai University, Optoelectronics country Ministry of Education, Science and Technology, Municipal Science Commission, the Planning Commission's support, aimed at thin-film amorphous silicon solar cells in this important direction of development in the four consecutive five-year plan assumed a major research project and the Ministry of Science and Tianjin Science and Technology Commission and major focus of research projects in the Nankai University has established an advanced multi-chamber continuous deposition of thin-film amorphous silicon solar cell pilot line, has made 15 scientific research achievements and patents.

The new mobile phone charger can be made universal

Ministry of Information Industry issued new regulations mobile phone lifebook t4010 battery network from June 14 onwards

By then, all produced in China a new application into the mobile phone network license and matching chargers have to be a unified interface.

It is understood that until now, including Nokia, Motorola, Sony Ericsson and other foreign brands as well as some domestic mobile phone handset makers have yet to participate in the standard, but because the standards are not mandatory standards, to buy foreign brands mobile phone consumers lifebook t4020 battery may the time being unable to enjoy a unified interface to bring the convenience of mobile phone charger.

17, the Ministry of Information Industry issued a "mobile telephones Jinwangjiance on the implementation of" mobile phones and chargers and interface technical requirements and test methods "notification" (hereinafter referred to as notification). Notification requirements, since June 14, 2007 at the mobile phone Jinwangjiance to start implementation of the new cell phone charger interface standard. By then, all produced in China a new application into the mobile phone network license and matching charger should comply with the relevant provisions of the standard YD/T1591-2006.

Reporter 17, learned that now includes a total of nearly 10 Chinese and foreign enterprises mobile phone brand up to more than 20 kinds of charger models. Afterward, the reporter interviewed several different brands of consumer mobile phones, which consumers have indicated a number of charger lifebook t4210 battery models too much, is very inconvenient.

There are a number of domestic mobile phone vendors have aggressively participated in the YDT1591-2006 standard, as a unified standard for enterprise cost savings. But including Nokia, Motorola, Sony Ericsson and other handset makers were not well-known international brands to participate in the standard, the fundamental reason for this is specifically for the Chinese consumers a unified interface to develop a new charger will definitely increase the cost of production of these international businesses .

Because of this non-mandatory standards, from the 17 Ministry of Information Industry issued a notice can be seen, although from June 14 on new network cell phone charger interface should be unified, but the notice did not indicate clearly who do not have a unified interface, mobile phone To network will be FPCBP155 fujitsu battery subject to what kind of limitations, and therefore can be predicted that June 14, China produced a new network within the foreign brands mobile phone charger, or "each singing its own tune," to buy foreign brands mobile phone consumers will be temporarily unable to Enjoy a unified interface, after the Chargers brought the convenience of mobile phones to buy foreign brands have to spend more money for the purchase of chargers.

The Democrats' fickle-and-dime health strategy

"Iwill not sign a plan that adds one dime to our deficits, either now or in the future -laptop battery - period," President Obama told Congress in a health-care address last month.

Well, that depends on what the meaning of "plan" is.

Senate Democrats wanted to protect sony battery doctors from scheduled cuts in Medicare payments over the next 10 years, but there was a problem: Doing so would add a quarter of a trillion dollars to the federal deficit, making mincemeat of Obama's promise. So Democrats hatched a novel scheme: They would pass the legislation separately, so the $250 billion cost wouldn't be part of the main reform "plan," thereby allowing the president to claim that that bill wouldn't increase the deficit.

Republicans, who had been losing traction in their effort to fight a health-care overhaul, could hardly believe the gift the majority had given them.

"I have never witnessed something more sinister!" an agitated Sen. Bob vgp-bps2a Corker (Tenn.) declared on the Senate floor Tuesday morning. Citing a report that the "doc fix," as the $250 billion measure is called, was created to buy the American Medical Association's support for the main health-care bill, Corker accused the AMA of prostitution. "We all know that the selling of one's body is one of the oldest professions in the world," Corker said. "The AMA is engaged in basically selling the support of its body."

While Corker was on the Senate floor suggesting that the vgp-bps2b Democrats were johns paying for sex, Jon Kyl (Ariz.), the second-ranking Senate Republican, preferred a reptilian metaphor. "They thought they were getting a problem off the table, and instead they grabbed a rattlesnake by the tail and don't know how to let go," he told reporters as he headed to a lunch with his GOP colleagues in the Capitol.

Around the corner, John Cornyn (R-Tex.), the man in charge of the Senate Republicans' 2010 campaign, opted for numismatic imagery. "This, of course, violates one of the president's first principles, when he said he won't sign any health-care bill that adds one dime to the deficit," he reminded reporters. "This adds a lot of vgp-bps2c dimes to the deficit." Two and a half trillion, in fact.

The focus of competition for electric vehicles - battery energy, power, life expectancy, the cost of Competition

Battery is the power source for electric vehicles. At present, the constraints of electric vehicles is a key factor in the development of battery power is not ideal. The major electric vehicle pavilion dv4000 battery, pavilion ze2000 battery, presario m2000 battery performance than energy, such as over power and life. To make electric cars can compete with the internal combustion engine car, the key is to develop high-energy than the power of large, long life, low cost of the batteries.

Lead-acid batteries

Lead-acid batteries have more than 100 years of history, is widely used as the internal combustion engine start-up power source for vehicles. It is also a mature battery electric vehicles, reliability, and raw materials, easy to get cheap; than power has basically been able to meet the power electric vehicle requirements. However, it has two major drawbacks; energy low, the share of the quality and volume too, mileage and shorter charge time; the other is a short life, the use of high cost.

Ni-Cd Battery

At present, the application of nickel-cadmium battery only to the extent of lead-acid batteries, the specific energy of up to 55W h / kg, than the power of more than 190W/kg, fast charging, long life cycle is the two lead-acid batteries times up to 2000 times, but the price of lead-acid battery for 4 to 5 times. Its initial acquisition cost, although high, but because of its color and life to advantage, so the actual use of its long-term cost was not high. But need to be used in recovery work, or heavy metal cadmium will pollute the environment.

Ni-MH battery

Nickel-metal hydride batteries and nickel-cadmium batteries, also belong to alkaline batteries, their characteristics and a similar nickel-cadmium batteries, nickel metal hydride batteries but does not contain cadmium, copper, there is no heavy metal pollution. As a result of higher prices had not yet been mass-produced. Estimated as the nickel-metal hydride battery technology, the specific energy of more than 80W h / kg, cycle life can be more than 2000 times, long-term prices can be reduced to 150 U.S. dollars KW h.

Sodium sulfur battery

Sodium sulfur battery is generally optimistic about the near future of electric vehicle batteries, has been the United States Advanced Battery Consortium (USMABC) as a medium-term development of electric vehicle batteries, sodium sulfur batteries mainly severe high temperature corrosion, battery life shorter. The use of performance stability and security issues such as less than ideal.

Zinc-air battery

Potential zinc-air presario v2000 battery, compaq presario v5000 battery, compaq presario v4000 battery energy than 200W h / kg or so, but it is currently still in a shorter life-span than the power of small, high-current output and can not be difficult to charge such shortcomings. CRX U.S. electric vehicle is loaded zinc-air batteries, the car to make up for its deficiencies, but also equipped with a nickel-cadmium batteries in order to help and accelerate the vehicle dispatch. CRX cars the quality of zinc-air batteries for the 340kg, can be fully charged the energy storage 45kW h at the same time up to 159kg of equipment CRX tin nickel batteries fully charged energy 4kW h after. CRX enable the 12-minute rechargeable electric car 65km, one hour charge will be traveling 160km.

Flywheel battery

Flywheel battery is the last century 90's before the new concept of the battery, it broke through the limitations of chemical batteries, using physical methods to achieve energy storage. A certain angular velocity when the flywheel spins, it has a certain kinetic energy. Flywheel battery in its kinetic energy is converted into electricity. High-tech type of flywheel to store energy, similar to the standard battery on. Flywheel batteries have a motor, the electric charge in the form of motor operation, driven from power, high-speed flywheel driven rotary motor, that is, power to the flywheel battery "charge" has increased the speed of the flywheel in order to increase its function; discharge , the electrical generators at the state of operation, in the flywheel, driven by external power output to complete the mechanical energy (kinetic energy) to electrical energy conversion. When the flywheel battery to give out the power, the flywheel speed gradually decreased, the flywheel of the flywheel battery is operating in a vacuum environment, and high speed (up to 200000rmin), the use of non-contact magnetic bearings bearings.

Fuel cell

A fuel cell is stored in the fuel and oxidizer in the chemical through the electrode reaction is directly converted into electrical energy generating device. It is not going through the process of heat engine, from the thermodynamic cycle constraints, it is a high energy conversion efficiency, fuel cell's chemical energy conversion efficiency of up to 100% in theory, the actual efficiency of 60% to 80%, there are the ordinary internal combustion engine thermal efficiency of the 2 ~ 3 times. Now used in electric vehicles in the fuel cell is known as a proton exchange membrane fuel cell (PEMFC), it is to pure hydrogen for fuel, air as oxidant. In 1993, science and technology exhibition in Vancouver, Canada, Canada's BALLABC the world's first company to launch a PEMFC batteries in electric-powered bus. 20 passengers can travel 160km / h, maximum speed of 72.2km / h. Mercedes-Benz pavilion dv2000 battery, hp pavilion dv6000 battery, hp pavilion dv2500 battery of Germany has developed a PEMFC battery-powered electric vehicles.

National People's Congress Chen Britain: a unified mobile phone batteries to avoid waste

"In our country, every year 200 million cell phone batteries-gd761, td347, inspiron 1501 battery and 100 million mobile phone charger into garbage, pollution is a waste also." March 12, the National People's Congress made on behalf of Chen-ying suggested that mobile phone charger and battery specifications unity, so that it can continue to use it.

According to statistics, in the world, a number of one billion mobile phones in use, and mobile phone users an average of 18 months for a new phone. In China, as at the end of October 2005, China's mobile phone popularity reached 29.1 / 100 people, 50% of users between one to two years in the replacement of mobile phones, and nearly 20% of users in less than a year on replacement of a cell phone, resulting in a large number of discarded batteries and chargers. The experiments show that the United States, an old cell phone batteries in serious pollution of cadmium to 60,000 liters of water.

CHEN Xue-ying suggested that cell phone batteries and chargers specifications, should be the same as dry-cell batteries, a uniform size, shape, specifications, can be used in different mobile phone batteries and chargers common. In this way, one can reduce the costs of manufacturers, mobile phone battery manufacturers Needless to reproduction, the performance of investment into research and development on mobile phones, reducing the cost of production will help reduce prices. Second, consumers can easily use to avoid non-rechargeable cell phone battery or forget to bring spare batteries and lead to calls, you can buy or borrow another person close to the battery. More importantly, take full advantage of the battery, reducing battery because the phone is not a result of common use were not caused by spam.

Britain's new battery can power home

Ceres British power company successfully developed a power of 1 kW fuel cell, can serve as a home "power station" for the average family to provide electricity and hot water.

Ceres power companies to develop fuel cell is different from the traditional to the hydrogen-powered fuel cell, which uses natural gas can generate electricity and thermal energy can also be generated. The use of new fuel-cell home prices are also very cheap boiler with ordinary boiler similar in ￡ 2500 to between ￡ 3000. The use of such fuel cells can also be used to spare the family the power sold to the national grid.

China's battery industry awareness of independent innovation

Held in January this year the "National Conference on Science and Technology and the National Science inspiron 6400 battery, dell inspiron e1505 battery, dell latitude 131l battery
and Technology Award in 2005 the General Assembly" and is not always the focus of industry participants in China's battery industry caused concern. Bank of China (Ningbo) Battery Co., Ltd. completed their own "LR6 batteries digital Wang and production lines and industrial research and development of" project in the General Assembly received the second prize of national scientific and technological progress. The industry believes that this means that China's battery industry has been gradually emerging from the "used" and the approach based on independent innovation of China's battery industry is from the "Made in China" to "Created in China."

Statistics show that the last century 80's, the Japanese Fujitsu, Toshiba, Panasonic and the United States, Duracell, Energizer and other international companies have research and production alkaline batteries. At the end of the last century 80's early 90's, Shuanglu, Nanfu, white and other Chinese companies "market for technology", through the introduction of alkaline batteries into mass production technology. However, as the core technology lies in the hands of international brands, in the downstream industry chain in China battery brand in the long-term under the shadow of an international brand. This shows that Chinese brands in order to occupy the domestic and international market the commanding point, it is necessary in the development of ideas from the "Made in China" to "China to create a" transfer. To achieve this shift, the only way of independent innovation.

According to the briefing, Shuanglu battery back in the last century, early 90's has invested 500 million yuan, based on large-scale technical transformation of independent innovation, promote the battery industry from low value-added products into high value-added products. National development in 2004 should be high-tech, sound energy of the call, the battery started Shuanglu national Torch Program projects - LR6 alkaline battery research and development of digital Wang. At present, products of its alkaline batteries LR6 has been one of the development of LR20, ZR6, ZR03, such as 12 series, basic alkaline batteries cover all product lines, and the initial realization of a mercury-free - than the state limit the deadline for nearly 5 years in advance. Independent innovation is a huge return, which for two consecutive years Shuanglu cell alkaline manganese batteries first in the country of export and profit, 4 years for the quality of alkaline manganese batteries ranked first in the country.

According to the industry expects the current global one-time battery is 3% -5% annual growth rate, its main direction is to develop high-performance, mercury-free alkaline manganese dioxide batteries of. China in recent years, high proportion of mercury-free alkaline batteries has increased to 30%, which is due to the introduction of the Chinese battery enterprises are self-developed high-grade mercury-free alkaline batteries. Analysts believe that as China's battery industry continuously enhance the awareness of independent innovation and new products, new production lines continuously, not only to the Chinese market 367759-001, hstnn-ib 09, pavilion dv1000 battery, but also to the global market have significant impact on the battery.

Panasonic will be February 20 of the products to market, its price will be 37,900 yen (about 355 U.S. dollars). Chengdu courtyard where residents have finally lost the place used batteries. Yesterday was informed that in order to achieve the objectives of the creation of Environmental Protection Model City, Chengdu, the first batch of nearly 100 recently has been a "battery recycling boxes" installed on a residential compound. Used batteries will be unified departments recovery, battery factory and then transported to the city for special treatment.

Battery recycling bins into the area, marking the beginning of the full establishment of Chengdu, the risk of waste collection system of classification, after the danger of the existence of disorderly conditions of garbage will be completely resolved.

Learned from relevant departments, a total investment of the risk of nearly 1 billion junk storage and processing center is expected to completed in the next year to deal specifically with used batteries, slag, smelting, as well as organic solvents, such as Java. According to the plan, the center occupies an area of a few mu, and mu in the next building on the landfill.

Fuel cell and hybrid

Fellow of the President of Honda Canada and the United States Yang thought that, by 2020, fuel cell and hybrid vehicle market share of 5-10%. However, many manufacturers, especially Toyota, it is even more optimistic about the oil, electric hybrid vehicles the future of the development dell latitude d500 battery, dell latitude d505 battery. Toyota and even that is not a fuel cell hybrid transitional technology, the future of all Toyota hybrid vehicles will be used.

It is reported that hybrid electric vehicles can use the battery energy storage and internal combustion engines. A battery-driven motor, in the first step, the engine idling, such as adverse working conditions at work, in order to achieve environmental protection and energy saving effect.

Those who support the hybrid view, this car has become a mature technology, the market has gradually begun to recognition, such as the Honda Insight, Toyota PRIUS in the United States and Japan have been used for many years, selling more than 100,000, a good energy saving effect , record breaking the record of the lowest fuel consumption.

Canada and the United States for its three-yang does not look that hybrid can not fundamentally solve the environmental protection, energy saving issues. Out of high oil prices unless otherwise how difficult hybrid market appeal.

Since there is a dispute hybrid, then, in the fuel cell vehicle technology is mature more than 20 years before, we will adopt environmentally-friendly car?

A pure electric vehicles is that some companies also do R & D carried out in this regard to try, but after all, pure electric vehicle market is limited, Moreover, it is difficult to solve the technical driving force for the weak, the charge cycle length, secondary pollution, such as old batteries therefore, pure electric vehicles such as buses only as a vehicle to use for specific purposes.

There is also often present in Beijing, the street will see liquefied petroleum gas (LPG) and compressed natural gas vehicle (CNG) vehicles, as well as ethanol and other alternative-fuel vehicles. Such vehicle is in the traditional basis of the engine, for other gas or liquid fuel. This is technically simple, but it can not fundamentally solve the energy and environmental protection.

And the general public, PSA and other European car company's plan, the promotion of large quantities of modern diesel cars. To this end, the FAW-Volkswagen also introduced the 1.9 liters of diesel Jetta SDi dell latitude d510 battery, dell latitude d520 battery cars, but diesel cars in China is also facing many problems such as fuel quality.

Canada and the United States Yang thought that, in fact, in recent years, major automobile manufacturers in the high efficiency, low consumption, environmentally friendly gasoline engine into a more energy, after all, gasoline engine in the future a long period of time will continue to dominate the market.

Should not focus on recycling used batteries

At present, Beijing has not used batteries to deal specifically with the manufacturers, more than 100,000 storage dell inspiron 500m battery, dell inspiron 510m batteries has become a big trouble. State Environmental Protection Administration, consultants, chairman of the China Institute of Environmental Science researcher Ye seek, in an interview with reporters yesterday that in fact, used batteries should not be focused on recycling, solid waste, together with a more reasonable sanitary landfill.

It is reported that Beijing residents used batteries collected are useful to focus on the garbage collection centers in Beijing, but also the handling of the battery or "storage." According to the Center to introduce a woman, they have received nearly 300 tons of used batteries, in the absence of a mature processing technology, these battery-only approach, the supply was sporadic laboratory experiment, and the rest are stored in several large containers.

"We are really not dealing with the mature technology used batteries. That is because now the battery has been very little pollution, even if the technology is developed to deal with is not really meaningful, so it does not by scientists to study." Ye demand, the batteries environmental pollution is mainly due to containing mercury, which is usually the "mercury", but the battery on the market for more than 95 percent of all mercury-free. Both nickel-cadmium batteries, or lithium electricity, hydrogen power, the pollution of the environment are very slight, slow, battery recycling and therefore there is no need for environmental protection. Another reporter has learned that at the end of 1997 China issued the "Regulations on restrictions on mercury content in batteries," which in 2002 had to stop the production of high-mercury batteries, and in 2006 to eliminate mercury-containing batteries. The survey also shows that scientific research units, both at home and abroad are not a result of serious pollution caused by waste battery case.

"On the contrary, to focus on serious pollution of the local potential." Yip said that the production of battery materials, including zinc, copper, graphite, asphalt, steel and other substances, and garbage in the landfill will be distributed together with the slow decomposition of the environment can be absorbed resolve. However, if the concentration of processing or storage of used batteries of heavy metals such as nickel-cadmium concentration exceeded in some areas, and even can lead to more serious secondary pollution.

Ye order also said that from an economic perspective, recycling of used batteries is also uneconomical. Some European countries and the United States, are not specialized agencies of the waste battery recycling. Ye seek to emphasize that compared with the dry-cell dell inspiron 600m batteries a large number of batteries containing lead, can seriously pollute the environment, and therefore needed to deal with the professional sector recovery.

Haikou battery market

Yesterday that the business sector from the sea, before and after the holiday, the business sector supervision in the market and found that the current of the 6y270, c1295 battery market in Haikou, there are many problems, the failure rate at around 20%.

It is reported that these problems can be found in the following areas: battery production date is not marked, and some do not have the production date and no expiration date; no site, no warning that the Chinese; not specify standards for the implementation of the standard number or code, or even individual products without negative signs; mark the site content is not accurate and so on. At the same time, there are a number of consumer complaints battery discharge standard content, a few days later with no battery power. This situation in a number of small shops and mobile vendors reflected particularly strong.
