3.2v 100ah lifepo4 battery.Lithium batteries for new energy vehicles need to keep up with the coordinated development of the entire vehicle

　　The annual forum of the China Electric Vehicle Hundred People Conference was held at the State Guesthouse. This forum is considered a grand event in the new energy vehicle industry. The theme of the forum is "New Ecology of Industrial Development", consisting of a closed door meeting of the Hundred Talents Conference, a high-end forum, and six thematic forums. The current research results of the Hundred Talents Conference are announced, providing a communication platform for the government, manufacturers, and enterprises. Experts and scholars have discussed the future development of new energy vehicles in China. This parallel forum will focus on the current situation and development of power lithium-ion batteries.

　　From the perspective of the current situation and development of power lithium-ion batteries. At present, the power lithium-ion batteries used in electric vehicles mainly consist of three chemical systems: nickel hydrogen batteries, lithium-ion batteries, and fuel powered lithium-ion batteries. Nickel hydrogen batteries are now very mature and widely used in the Prius hybrid. The lithium-ion batteries we are currently discussing include lithium iron phosphate, lithium manganese oxide, nickel cobalt manganese oxide, and nickel cobalt aluminum oxide. The latter two are called ternary systems. Therefore, from the table, it can be seen that the current lithium-ion battery has transformed from lithium iron phosphate to ternary, with a monomer energy of up to 180. It can be seen that there is still some development space for this ternary material battery, and the final density can reach 250 or even 260, which is currently a direction of the industry.

　　And fuel powered lithium batteries have made significant breakthroughs. The energy density reaches 3000 watts per liter and the durability reaches 10000 hours. At present, the important issue is cost and hope for further reduction. First, let's take a look at the development status of our country. Our judgment is that we have basically mastered the key technologies of lithium-ion batteries for automotive power. The development of lithium-ion batteries in China is basically synchronized with the overall vehicle. During the "Tenth Five Year Plan" period, we conducted research and development work on nickel hydrogen batteries, lithium manganese oxide lithium-ion batteries, and fuel power lithium-ion batteries. During the 11th Five Year Plan period, we increased the research and development and industrialization of lithium iron phosphate batteries. During the 12th Five Year Plan period, we promoted the research and development and industrialization of ternary material batteries. At present, we are in such a stage.

　　Technically speaking, China has developed nickel metal hydride batteries and lithium-ion fuel power lithium batteries, with key technical indicators reaching the advanced level of similar products abroad. At present, lithium-ion batteries in China can achieve a system specific energy of 800-1000 watt hours, a specific power of 500-100 watt hours, a cycle life of over 1000 times, a service life of about 5 years, and a cost of about 3 yuan per watt hour. Secondly, from a product perspective, lithium iron phosphate batteries have matured. In the past, the batteries supplied by China supported the development of the industry. At present, most of the batteries used for large-scale demonstrations are domestically produced.
