Lead-acid, nickel hydrogen, lithium cost, stability, performance indicators and so on their own merits, has been controversial. At the recent development of new energy vehicles in China Summit Forum on China Battery Industry Association, Executive Vice President and Secretary General Wang Jing Zhong Li said the book, in the future lithium iron phosphate power battery is a dominant direction.

Vice Chairman of TOSHIBA PA3384U-1BAS Battery Industry Association, chairman Zhang day to day is diametrically opposed to any proposed, at present and in the next 10 years, 20 years, lead-acid batteries in the whole field of new energy including renewable energy will still account for a major position in.

In the new energy vehicles, electric cars are most concerned about the choice of technology is more realistic. Industrialization of electric vehicles is the key battery.

According to the Ministry of Industry and published in 2009 the "new energy automobile manufacturers and product access management rules," the new energy automotive products into initial stage, development stage, mature stage of the three different techniques. An initial stage of fuel cell vehicles, electric vehicles is the development of lithium batteries, lead acid battery electric vehicles are mature products.

Wang Jing Zhong said that the line from the power cell technology development process to see, first is lead-acid batteries, and later Ni-MH battery, lithium ion battery further. Lithium iron phosphate security and performance are very good, and now countries are focused on technology research, which is leading the future direction of a battery.

Zhang Tian-ren, it makes a different view, he said: "The lead-acid battery technology is more mature than the lithium batteries, the state and industry standard sound, a more abundant mineral resources, the future of new energy vehicles can more easily enter the commercialization stage."

As for the fuel cell, Wang Jing Zhong believes that it is absolutely environmentally friendly batteries, but to invest in R & D is very high, the main bottlenecks are as enzyme concentration of platinum in the world is very small, electric vehicles are put to hundreds of million just to solve the electric car production, there is a big problem in the future popularity.

Experts for the Ni-MH battery will quit the stage of history is formed consensus.

Who is the first choice for industrial

Which technology is currently more practical route of electric vehicle batteries should choose the direction of industrialization? Japan Securities Research Fellow Fan Kai Yu letter said, according to statistics, 90% of the electric car models using the battery Japan and South Korea, technical route to increase ternary lithium manganese-based materials.

Lithium iron phosphate is a good R & D direction, but the current price is higher in the short term is difficult to reduce. Tianjin, China's second-largest lithium battery company Valence power of God U.S. imports of raw materials prices of 35 yuan / ton.

PRACTICAL TRADITIONAL Merchants Securities researcher believes that the lithium battery industry chain is not mature, although the price of lithium manganese oxide is relatively low, but the instability of the shortcomings, which products to occupy the mainstream of the future can not say.

Domestic listed companies, IBM THINKPAD R60 Battery, battery Huafang textile production, China Baoan and other production of lithium iron phosphate, Shanshangufen main attack ternary materials and lithium manganese oxide, CITIC Guoan, Tibet, having the upper reaches of lithium mining resources.
