U.S. cobalt prices fell again in Europe

June 23 electricity traders said, as a long-term impact of delivery, the U.S. and European markets Cobalt prices fell again. MW offer a variety of grade cobalt prices have been decreasing, and BHP Billiton and Norilsk’s cobalt offer also reduced.

But the reaction of consumers is not good, because summer break is approaching, wait and see on the market sentiment is growing. But this practice of selling long-term delivery were some people that are risky, and one view is that once the stock BHP Billiton tensions, bidding up, there are great risks to do so. Also that the Norilsk offer of behavior is to reduce damage to its own interests, as it sold OMG1100 million pounds per year of cobalt, or 1 U.S. dollar per pound, it means that it has withstood the loss of 11 million U.S. dollars. In this view, every summer the same thing happen, and ultimately with the manufacturers reduce inventory, pricing will be to reproduce the reaction.

The enthusiasm of consumers still good, still need to take that that to buy a decentralized procurement approach. Consumers have said, when it resumed in August after their normal production, there may be a normal purchase. He said although the trading volume in the press that he determined to buy, so you can get a lower price, but he can not guarantee that in August the number of their needs, so he does not agree with this strategy traders. He added that now traders will pull down prices, they can at the 4th quarter to enhance the higher cobalt prices, more profits.

Industrial battery industry market

The gap between technology and manufacturing a profound impact on the market, industrial battery industry

"The more you look, the less you know" is no doubt we are in the process of writing this report most experience.

We have been thinking, what is the power of the battery industry? We believe that every application of new materials for a qualitative leap in battery performance, each anode and cathode materials also contributed to the improvement or electrolyte batteries have a certain level of quality improvement.

History of the battery, it is a material advancement of technology history. Quantitative improvement of the battery technology, the invention of new materials to promote qualitative change in the battery. Can be expected, the use of conductive material containing the element lithium (ionic compounds, polymers) as the electrode material is the best choice for high-energy battery, but, multi-element compounds found in lithium-ion materials technology needed to continue to progress.

Enhance the energy storage potential, improve energy density, this battery technology is always evolving concept of one of the most direct. However, the perfect person does not yet exist, especially for high power and high energy is difficult to have both. Moreover, we will find that different products have diverse needs of the battery.

Thus, the development of battery materials is diverse.

Contrast the appearance of performance, safety, price, life are all indicators must be considered, which determines whether certain widely used battery. Because, superior performance lithium-ion battery, different cathode materials for lithium ion batteries to meet the cost differences between market demand for different applications, therefore, the formation of lithium-ion battery cells for other types of alternative trend is almost full.

Despite our impression that the battery is labor-intensive manufacturing, but the battery industry chain from the point of view, is also a technology-intensive, especially in resource mining and processing and battery materials preparation more involved in materials science. Lead-acid batteries through the icon, nickel hydrogen batteries, lithium-ion batteries manufactured by the main process areas, we pointed out the direction of development of the domestic battery industry and technical bottlenecks.

In the battery industry, China and Japan, there is a considerable gap between the United States, which ultimately can be reflected in the materials technology gap between the domestic and foreign industry. We believe that relying on imports of battery materials, the manufacture of small single cells are mature; But even solve the problem of battery materials, high-capacity high-power battery pack design and manufacturing continues to face many problems, which is the electric vehicles battery technology needs to break the key technical difficulties.

Business transformation from the perspective of the development of China Battery, Lithium-ion battery industry competitiveness in the market depends heavily on the accumulation of long-term development of the technology, rather than pure capital investment, and similarly, lithium battery materials with high technical barriers, the small sub-industry leaders who are mostly early entry into the industry. However, the small lithium ion battery business, technical threshold is low, the influx of a large number of small participants led to the rapid decline in industry profitability.

China's entry into emerging industrial super-capacitors

Super capacitors is between the capacitor and battery energy storage device between the China Heilongjiang, Harbin Ju Yung, accredited independent research and development of super-capacitors, the technical leader in the international arena, with independent intellectual property rights, the level of product technology similar to similar products with Russia. Russian products are of the 17th International Electric Vehicle Council (EVS-17) evaluation as currently the most advanced super-capacitors, intellectual property value of $ 200,000,000. It has a quick charge and discharge capacitor characteristics, but also has the mechanism of electrochemical energy storage battery.

Supercapacitors can be divided into two categories: (1) activated carbon as electrode material to the electrode double layer capacitance charge storage mechanism, commonly referred to as double layer capacitors (DLC); (2) ruthenium dioxide or conductor polymer and other materials for the anode to the mechanism of redox reactions to store charge, commonly referred to as electrochemical capacitors.

As a new energy storage devices, electrochemical capacitors with high capacitance can even thousands Farah Da Fala level, to achieve rapid charge and discharge and high current power generation and power than the battery has a higher density (up to 1,000 W / kg of magnitude ), and longer cycle life (charge and discharge times up to 10 million), while at very low temperature extreme environments, and no environmental pollution. These features make electrochemical capacitors in electric vehicles, communications, consumer and entertainment electronics, signal monitoring and other areas of power | voltage regulator applications have broad market prospects.

Some industry experts predict, just from the Chinese market, the current annual demand of up to 2,150 million, while total demand throughout the region and more than 9,000 million. U.S. market research firm Frost & Sullivan recently released a report is also expected, between 2002 and 2009, the global super-capacitor industry output and sales revenue data will be in both 157% and 49% compound annual growth rate to maintain growth.

Lithium Battery Energy saving Upsurge

With the constant fluctuations in international oil prices, energy saving environmentally friendly lithium battery in the limelight once again a hot topic. From 6 months, the number of international auto companies and electronics companies are using large-scale lithium battery joint investment. Including Toyota and Matsushita, Nissan and NEC, Volkswagen and Sanyo, Bosch and Samsung, they believe that lithium batteries in the next few years will gradually replace the nickel-metal hydride batteries, lead the direction of development of hybrid vehicles. Li-ion battery in the heat of global investment background, China's automotive enterprises in this research work is in what kind of? Experts on the lithium battery is holding what kind of attitude? Recently, the reporter interviewed specifically on this issue who has studied the domestic lithium battery, several experts.

Beijing Institute of Electric Vehicle Engineering Center Deputy Director Lin Cheng

Study of lithium iron phosphate has been a breakthrough

Lin Cheng told reporters, demanding automotive lithium batteries. It requires that the vehicle used in a variety of conditions, must protect the security, can not occur fire, explosions and other accidents. The first was for battery electric vehicles, in this country has made great breakthroughs have begun to take industrial scale. But 5,6 years ago, with the battery powered vehicles are often some accidents, such cells will gradually be diluted. Now, the domestic lithium battery research progress quickly, especially in the battery safety issues, has made great progress.

Lin Cheng told reporters, lithium batteries include lithium manganese oxide and lithium iron phosphate batteries. At present, the development of the domestic lithium manganese oxide has begun to take shape. Lithium iron phosphate as safer, longer life, will become an important direction for future development of lithium batteries, but also abroad, the focus of research and development of the automobile. At present, lithium iron phosphate studies of good progress, especially in some of the patent on a breakthrough, this time for the Beijing Olympic Games is a passenger car with a self-developed lithium iron phosphate lithium battery.

"Of course with the study abroad compared to lithium batteries, the domestic lithium battery research still lags far behind, but the domestic lithium battery emphasis on increasing, the future will be the R & D focus." Lin Cheng told reporters.

Henan Huanyu Group lithium battery industry technology Deng Lun-ho, deputy chief engineer

Large-scale lithium batteries for electric cars need some time

Henan Huanyu Group is a component from the battery to the battery cell manufacturing plastics and related hardware, equipment manufacturing, electronics manufacturing, a complete industrial chain of the Enterprise Group, has undertaken the project of Science and Technology Li-ion battery research and development.

"At present the domestic lithium battery research and abroad, the gap is mainly reflected in the battery control system and power management systems." Deng Lun-ho told reporters that now the domestic lithium battery research for development in their respective state. Currently, some companies have been able to provide the corresponding lithium battery electric vehicle accessory products, supporting the general lithium batteries can run 200 to 500 km.

Deng Lun-ho told reporters that now the price is too high the domestic lithium battery, power management system problem has not yet been well resolved. Charging electric vehicles also face the problem. Currently, the general line at home can not charge lithium batteries for electric vehicles must be equipped with a small dedicated charger, and charging time is very long and very troublesome. Abroad, in order to solve this problem, generally regarded charging stations and gas stations together. China is now charging stations have not established a large scale.

Deng Lun-ho believes that the current consumer acceptance of electric vehicles equipped with lithium batteries it still more difficult: "the price of an ordinary electric car is about twice the same configuration or even higher gasoline locomotives, domestic consumers have not enough economic prepared to accept the power and electric vehicles. "

China Electric Power Research Institute engineer Chuang Feng

Optimistic about the prospects for the development of lithium iron phosphate

Chong Tong, told this reporter, the electric vehicle battery research and development work has gone from lead-acid batteries, nickel-metal hydride batteries to the development of lithium batteries, each battery advantages and disadvantages.

The earliest to appear in lead-acid batteries, used in the longest time, belonging to the battery series. The best safety performance lead-acid batteries, rare explosion, fire and other phenomena, energy storage effect is not ideal. Later, people developed a nickel-metal hydride batteries, store energy and power than the effect of the ideal lead-acid batteries, but due to nickel-metal hydride battery in the charging of hydrogen generated in the process prone to explosion, so the nickel-metal hydride batteries in a business may or may not state.

To the year 2000, people developed a lithium battery. Lithium batteries are lead-acid storage battery of power 2 to 3 times, but because it contains lithium-ion active in the metal layer surface, prone to spontaneous combustion in the air, explosions, etc., higher risk. So now the major countries is to control the development of lithium batteries is safety and stability.

"Charging a lithium battery would be able to cycle around 1000, in which the stored energy of lithium iron phosphate is better than lithium cobalt oxide and lithium manganese oxide effects worse, but it's the best safety performance, than lead-acid battery energy storage much higher, so now the most promising lithium iron phosphate. "Chuang Tong said.

Society of Automotive Engineers of China, director Chen Quanshi branch of electric car

Three problems of domestic lithium battery research

Quan-Shi Chen said in an interview: "Now the state attaches great importance to the study of lithium batteries, '863 'project, the state invested a total of 66 million yuan, all development work for the lithium battery. We and Japan, the United States such as walking in the lithium battery research and development in the forefront of the developed countries, China's lithium battery manufacturing precision, equipment, standards, etc. there is a certain gap between R & D details. "

Quan-Shi Chen told reporters that at present there are three issues of domestic lithium battery research. The first is the consistency of manufacturing. Since the lithium battery manufacturing technology and equipment there is a gap, the domestic lithium battery production technology mixed, manufacturing standards has not yet reached agreement. Lithium batteries used in electric vehicles are connected in series or in parallel, if the consistency issues are not well, then the large-scale production of lithium batteries used in electric vehicles will not be able.

Followed by the intellectual property rights. Currently in the study of lithium iron phosphate has made a breakthrough, but the U.S. patent in this area, so although some of our links to independent research and development, but in intellectual property issues, but also do not know how to respond.

The third issue is the selection of raw materials. Now the production of raw materials used in lithium batteries can not all imported, mainly from China, but domestic raw materials, through international certification, to produce lithium-ion batteries in order to be internationally recognized, so the link in the certification of raw materials and also some problems.
