In the recently held "2018 the first new energy cars and power battery CIBF (Shenzhen) international conference "in the" contend. Business model innovation and application of "-- special business model on the BBS, Zhejiang ao, optimal power system co., LTD. (hereinafter referred to as" ao, optimal power "), general manager of Dr Chen Guangsen published titled "the industrialization and application of the next generation of power battery" keynote speech.
As China's new energy automobile subsidies TuiPo entered the final countdown for two years, the development of power battery industry will enter a new stage.Chen Guangsen power battery industry profits this year as a whole are expected to range in the profit and loss balance.With the development of new energy automobile industry gradually transformed into a market driven, at the same time, both technical and cost advantages of power battery will be more competitive, and the present stage of manganese acid lithium, lithium iron phosphate, ternary material such as lithium electricity system on the cost and technology it is hard to have it all, it is difficult to meet the needs of new energy vehicles to power battery.
In Chen Guangsen view, rich lithium manganese material will probably be to guarantee the healthy development for the next generation of new energy automotive industry lithium battery material system.In recent years,The ternary lithium ion batteries upstream lithium cobalt, crazy prices for raw materials, has been in the industry.According to Chen Guangsen, rich lithium manganese mainly for manganese acid lithium and ternary Shared body, it can be done cobalt, nickel content is only ternary lithium ion batteries about a third, even do not containing cobalt, cost and manganese acid lithium is close to.At the same time, the rich lithium manganese g capacity is 300 mah/g, and manganese acid lithium is far higher than three yuan.In addition, rich lithium manganese in safety is better than that of the ternary lithium ion batteries.Chen Guangsen, said rich lithium manganese manganese acid lithium power battery set, three yuan, and the advantages of lithium iron phosphate, with low cost, high energy density, long life and high security, two to three years is expected to become the mainstream of power battery products, provide guarantee for the electric car popularity.
As far back as 1992, argonne laboratory is first put forward the rich lithium manganese anode material, but because of its poor electrical conductivity, low efficiency and supporting electrolyte for the first time is higher than the common technical difficulties such as electrolyte electrochemical window has been no breakthrough, hindered the development of rich lithium manganese base material.According to Chen Guangsen, ao, optimal since 2010 engaged in rich lithium manganese base power battery research and development, after eight years of r&d, ao has a major breakthrough in technical research, and in the world take the lead to achieve the industrialization of rich lithium manganese batteries.
Chen Guangsen admits, rich lithium manganese material in the mass production there are still some technical problems need to break through, but the rich lithium manganese material has made breakthrough progress in the performance ratio, already can do super long cycle life and fully comply with national standard 3 c / 1 c discharge capacity > 90%.In addition, in the rich lithium manganese ao, optimal power battery industrialization can make way more enterprises pay attention to the rich lithium manganese battery industry.He believes that in the next two years rich lithium manganese technology progress, substantially boost the development of new energy vehicles industry.
According to Chen Guangsen, ao, optimal power at present basically has manganese acid lithium, ternary material, lithium iron phosphate, lithium titanate and other mature power battery material system and a new generation of rich lithium manganese material system.At present, the company rich lithium manganese power battery energy density batteries have done 220 wh/kg, battery energy density of 140-160 wh/kg.Among them, the company launched AYP128188236RLM50 series rich lithium manganese batteries, batteries energy density has reached 240 wh/kg.According to ao, optimal power lithium manganese based power battery research and development planning, by 2020, ao, optimal dynamic stable production 300 wh/kg rich lithium manganese battery power.
Chen Guangsen said finally, rich lithium manganese is easier to meet the electric car "long life, high safety, low cost" demand, can make electric cars in the absence of subsidies make ordinary people can afford.
