Lithium War Over the World

Since June, a number of international auto companies and electronics companies are using large-scale lithium battery joint investment competition. This includes the Toyota and Matsushita, Nissan and NEC, the public and Sanyo, Bosch and Samsung, they believe that lithium batteries in the coming years will gradually replace the nickel-metal hydride batteries, lead the direction of development of hybrid vehicles. At a time when Chinese auto companies are working to develop the nickel metal hydride battery assembly of hybrid cars in order to focus on display during the Beijing Olympics.

According to report, the stability of lithium batteries due to fears from the "15″ begins, in the new energy vehicle development process, not to focus the direction of lithium, but chose Ni-MH battery.

June 26, the National 863 Program, "Energy-saving and new energy vehicles," major projects team leader Ouyang Ming Gao said in an interview, in lithium batteries, the domestic and foreign advanced level yet. Alone no problem in terms of battery materials, the performance of a single cell is not worse than the advanced international level. But the composition of the battery pack, its stability, consistency of production, service life, there are still big problems.

Lithium War

According to public reports, in order to reduce risks and improve technology industrial efficiency, a number of international car manufacturers and electronics manufacturers have chosen the way of co-energy lithium battery of new car development.

Toyota and Matsushita's Panasonic EV Energy joint venture company will build two hybrid battery manufacturing plant, from 2009 production of lithium batteries, and Toyota are scheduled to assemble the first car in 2010 sold plug-in hybrid vehicles, plug-in hybrid power car battery can be charged by domestic supply.

A global leader in lithium battery production – Sanyo Electric Co. will start mass production car by the end of 2009 lithium batteries, jointly developed with public control. In addition to the general public, the Sanyo is also with Ford and Honda to develop lithium batteries. Sanyo's goal is to 2015, occupation of the global car market with more than 40% share of the lithium battery. Sanyo also can be used to speed up the development of a plug-in hybrid electric cars lithium battery, and strive to begin selling the product in 2011.

Nissan and NEC announced joint production of lithium batteries, and plans to launch in 2010 assembly lithium battery electric vehicle.

General Motors and South Korea's LG Chemical Company's CompactPower companies and Continental Automotive Systems signed a contract two lithium batteries.

Japan's GS Yuasa, Mitsubishi Corporation and Mitsubishi Electric Corporation has invested 3 billion yen (about 190 million yuan) build a Japanese lithium Energy (LithiumEnergyJapan). Mitsubishi Motors will begin selling in 2009, hybrid vehicles, and in mid-2010, sales of pure electric vehicles.

With the formation of the capacity of these investments is gradually released in 2012, the lithium is likely to replace the nickel-metal hydride batteries. Vice president of Geely Automobile Research Zhang Tong told reporters, according to his understanding, this year, Mercedes will have lithium batteries for hybrid assembly of a type listed.

China line

Previously, the stability of the domestic industry are generally considered poor lithium use may occur because of spontaneous combustion temperature is too high, the actual trial in domestic enterprises, also have occurred in vehicles equipped with lithium burning case, therefore, not be lithium batteries as a key R & D direction, but chose Ni-MH battery. It is understood that "10

Five "period, the nickel-hydrogen battery R & D investment is much greater than lithium batteries. However, large multinational corporations mean that domestic investment in lithium-related technology may have to re-route options?

Domestic research and development of hybrid type, such as FAW Pentium hybrid, SAIC Roewe 750 hybrid Chery A5 hybrid, hybrid, etc. Long An Jiexun are using nickel metal hydride batteries.

However, even technical line to adjust the short term is difficult to catch up with international advanced level.

Zhang Tong said that according to his understanding, the international advanced level of control on the lithium battery has been sympathetically, about to break through the bottleneck stability. According to the business community to reflect the domestic lithium battery materials, batteries monomer / component processing technology, control of key technologies such as batteries still awaiting a breakthrough. Moreover, the issue of consistency of production has not fully resolved, does not have the production capacity.

So far, China has no battery joint research and development companies and auto companies situation. "Eleventh Five-Year" Plan 863 "energy saving and new energy vehicles," major projects, the participation of lithium battery research and development of enterprises and research institutions include: Beijing Nonferrous Metal Research Institute, Suzhou Star Constant Power Co., Ltd., Tianjin Lishen Battery Co., Ltd. and CITIC UNITA solid for the new Energy Technology Co., Ltd..

Zhang Tong said that in the lithium battery field, Chinese enterprises still have a chance. Because our country had to develop consumer electronic products for the lithium battery industry has laid a good foundation conducive to the development of battery in the field.

A welcome change, industrialization has become the "during" the main direction of development of lithium batteries. "Energy saving and new energy auto project," the general members of the Group, Tongji University Dean of Zhuoping car told reporters that the company take lithium battery R & D projects have also been asked in the "Eleventh Five-Year" end of the formation of a certain amount of production capacity.

Zhuoping that reliability will require substantial funding reform process, additional equipment. "Eleventh Five-Year Plan" period, the central government will invest 60 million yuan Li-ion battery development, the company also asked to assume the project inputs in accordance with the ratio of 10 times the matching funds, so that the total investment will reach 600 million yuan. According to report, "15″ period, the lithium battery research and development on the national allocation of funds, only 800 million with local matching funds, only about 16 million yuan.

Although the "Eleventh Five-Year" period of the input greatly increased, but compared to the huge multinational investment, domestic investment remains low. It is understood that only a company's lithium batteries Sanyo project investment reached 800 billion yen (776.7 million U.S. dollars).

Cross or follow?

The face of new energy vehicles and the overall status of the development of the backward, the industry began to rethink some of China's automobile industry development strategy by leaps and bounds.

In 2000, just returned near Wan Gang told the State Council put forward the development of clean energy vehicles, China's auto industry to achieve leapfrog development strategy. The basis of this theory is: in the field of electric vehicles in this new and foreign in our starting line similar level of technology and industrialization gap between the relatively small, vigorously develop a new generation of industrialization as a vehicle to promote the domestic automobile industry by leaps and bounds development of strategic initiatives, there may be a new round of competition in the world automotive industry occupying high ground, to obtain a favorable position to improve the international competitiveness of the domestic auto industry.

Early 2006, when he was "15″ electric vehicle major science and technology projects of the overall team leader, said Wan Gang, Dongfeng, Chang'an, Chery and FAW hybrid electric car from 2006 onwards the market. Chery said in 2007 to achieve the industrialization of hybrid vehicles to achieve 30 000 production.

However, to date, our country has not a mass production hybrid vehicles. By this time, to hybrid Toyota Prius has been known in the global sales of 1 million.

June 26, the National Development and Reform Commission spokesman told reporters that the domestic development of the current line of cars followed the international advanced level is because we in this area beyond and innovative strength is still insufficient. While still upholding the direction of the simultaneous development of multiple technologies, when the direction of adjustment of international development, they can promptly adjust, and will not touch. The hybrid vehicles are on the domestic rate of industrialization is not optimistic.
