In the new energy vehicle development strategy in countries and regions all over the world have been based on their assessment of different options, the relevant battery technology research and development and hp pavilion dm3 battery, hp pavilion dm4 battery to promote support for taking a different strategy. From the current situation as a whole, Japan and the United States and Europe focused primarily on lithium batteries and fuel cells, but our country as taking into account the resources and technology maturity, in the newly released policy emphasis on promotion of nickel-metal hydride batteries.
"Ni-MH - Lithium-Ion battery - fuel cell," Industrialization Path
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 basic theory, 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 toshiba pa3465u-1brs battery, toshiba pa3734u-1brs battery, followed by nickel-metal hydride battery technology and lithium iron phosphate, hydrogen fuel 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 battery can not be replaced in 2 ~ 3 years, nickel-hydrogen batteries, mainly due to cheaper nickel-hydrogen battery safety, has 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 Ni-MH rechargeable battery-vehicle global market scale than the previous year by 23.7% to ¥ 92,000,000,000, but the 2015 Ni-MH rechargeable battery-vehicle market will fall to ¥ 55,000,000,000.
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 dell inspiron 1564 battery, dell inspiorn 1764 battery 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.
Experts believe that the reason why countries are now the focus from the development of lithium batteries into nickel-metal hydride batteries, the main reason is that nickel-metal hydride 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.
The market demand sony vaio vgn-aw keyboard, sony vaio vgn-ns250 keyboard for nickel-hydrogen batteries to bring 2-3 years of rapid growth in
Nickel-hydrogen battery technology, and industry chain to determine their maturity will be a period of time with the coexistence of lithium batteries, lithium iron phosphate cathode material for lithium batteries makes the emergence of performance and cost advantage has been achieved, but the stability of production capacity deficiencies and the lack of inspection of the actual operation continues to be a part of the new energy discourage automobile manufacturers; In contrast, nickel-hydrogen batteries have gone through years of actual combat, technical and industrial chains are quite perfect, in a short time can be formed on the vehicle's stability and supporting capacity, and therefore can still be a period of time in the new energy vehicles widely applicable.
According to industry estimates, nickel-hydrogen battery market is still expected to get 2-3 years of rapid growth in the next 2-3 years, the "10 City 1000" program, the increasing popularity of hybrid cars and export in overseas markets for nickel and other factors to bring hydrogen-powered battery market demand for strong growth, and when the nickel-metal hydride batteries and lithium batteries are still Nanfenbozhong when the nickel-hydrogen batteries will usher in a short period of rapid growth.
Among them, China has launched a "10 City, 1000" Plan will bring the first batch of nickel hydrogen battery market demand. It is estimated that in the "10 City, 1000" program, about 3200-4000 vehicles, new energy vehicles (including buses and passenger cars) using Chinese-made nickel-hydrogen batteries, within three years, bringing a total of about 3.5-4.4 million kilowatt-hour hp probook 4510s battery, hp probook 4710s battery nickel-hydrogen battery needs.
Taken together, both domestic and export demand weakened after the 2012 nickel-hydrogen batteries will gradually be replaced by lithium batteries.
Keep up the pace of R & D policy
In China's automotive battery production enterprises with a production capacity of nickel-hydrogen batteries accounted for the majority of companies, including Chunlan Group, Ke-li Yuan, the torch high-tech, Hunan Shenzhou, Kane shares, etc., which Chunlan Group is the nickel-metal hydride HEV power battery technology, leading market share in a leading position in the torch high-tech and Hunan Shenzhou has possessed a certain amount of technical base and market position.
As for the lithium battery, most domestic manufacturers do not have the ability to mass production, but the relevant production planning has been implemented, it is expected after 2010 be able to mass production.
Experts believe that, technological advances, China's car prices and the related battery business in addition to promoting the industrialization of nickel-metal hydride batteries, more attention should be put some of the long-term, to devote human resources to carry out power lithium battery research and development lenovo thinkpad sl410 battery, lenovo thinkpad sl510 battery, and to maintain the fuel cell technical follow-up, in order to occupy a broader new energy car market ready.
