Ni-MH battery to become the focus of China's current policy support In our letter to the Department of Public June 25 that the new energy automobile manufacturing companies and product access management rules, the vehicle according to the new energy vehicles, systems and key assembly technology maturity, degree of perfection of the national and industry standards, and industrial the degree of difference will be divided into initial stage 'where the development period, three different stages of technology maturity, and give classified management. In accordance with state regulations, start-products only in small volume production, and only in approved areas, scope, duration and under conditions of model runs, and the operational status of all products for real-time monitoring; development stage product allows for mass production only the approved area, scope, duration and conditions of sale, use, and at least 20% of sales of products running in real-time monitoring; mature products and conventional automotive products, vehicle manufacturers and product announcement Management the same way, in the sale and use of the same as with conventional automotive products. This means that, in China, December 31, 2010, equipped with lithium battery hybrid and electric vehicles will be limited to the sale and use areas, the use of nickel-metal hydride battery hybrid and electric vehicles can be sold and used across the 'country.
In the commonly used three kinds of car batteries, lead acid batteries due to serious environmental pollution has long been out of the mainstream applications; nickel-metal hydride batteries, although the commercialization of the mainstream at present, but the key indicators of laboratory data were lower than lithium batteries, and the theory basically there is no room for; lithium batteries despite the superior performance, but still can not be guaranteed safety, and the relatively high costs have also hindered its commercial. 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 batteries, nickel-metal hydride battery technology since the most mature in the next three years, will remain the mainstream of new energy vehicles, followed by nickel-metal hydride battery technology and lithium iron phosphate , hydrogen fuel cells, one-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 battery can not be replaced in 2 ~ 3 years, nickel-hydrogen batteries, mainly due to cheaper nickel-hydrogen battery safety, Have reached large-scale production. Lithium batteries also need to continue to research topics, such as security, so take time commercial. 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 battery will gradually erode the market share of the nickel-metal hydride batteries, the agency predicted in 2009 car-use nickel-metal hydride re'chargeable batteries in the world size of the market than the previous year by 23.7% to ¥ 92,000,000,000, but the 2015 Ni-MH re'chargeable battery-vehicle market will fall to ¥ 55,000,000,000.
