In the new energy vehicle development strategy,countries and regions all over the world have been based on their assessment of different options, they are taking a different strategy to promote support for the relevant Canon NB-2LH battery technology research and development and . From the current situation as a whole, Japan and the United States and Europe focused primarily on lithium batteries and fuel cells, but as taking into account the resources and technology maturity, in the newly released policy,China emphasis on promotion of nickel-metal hydride batteries for Kodak klic-8000 .
Although Ni-MH battery is the commercialization mainstream , but the main indicators of laboratory data are lower than lithium batteries, and for the basic theory, there is no room to improve;despite of the lithium Dell precision m series battery superior performance , but safety still can not be guaranteed, and the relatively high costs also impede their business.
Experts predict that the new energy vehicles will be in the “Ni-MH – Lithium-Ion battery – fuel cell” industry-oriented development path. From the development trend and rate, and short-term performance can be realized only nickel-hydrogen Dell precision m90 series battery , since nickel-metal hydride battery technology is the most mature in the next three years, it will remain the mainstream of new energy vehicles, followed by nickel-metal hydride battery technology and lithium iron phosphate, hydrogen fuel are cell-third of the world, 5-year lithium batteries and will be gradually replaced by fuel cells.
Battery giant Panasonic and Sanyo also found that the lithium-ion Sony NP-FP70 battery can not replace nickel-hydrogen batteries in 2 ~ 3 years, , mainly due to cheaper nickel-hydrogen battery safety,it has reached large-scale production.
According to Japan’s Fuji economic analysis, the mainstream nickel-metal hydride batteries will be able to continue until 2011, but after 2011, Li-ion Kodak KLIC-8000battery will gradually erode the market share of the nickel-metal hydride batteries.
In our letter to the Department of Public June 25 that the “new energy automobile manufacturing companies and product access management rules” from China , the vehicle according to the new energy vehicles, systems and key assembly Nikon EN-EL3 battery technology maturity, degree of perfection of the national and industry standards, and industrial the degree of difference it will be divided into three different stages of technology maturity, and is given classified management.
Experts believe that the reason why China now focus from the development of lithium batteries into nickel-metal hydride batteries, the main reason is that nickel-metal hydridePanasonic CGA-DU21 battery technology is more mature than the lithium batteries, more abundant mineral resources, the future of new energy vehicles will enable greater access to the commercial phase.
