These three types of battery with the highest energy density of lithium cobalt oxide, but it is also the most unstable at high temperatures; lithium iron phosphate, the most stable, but the lowest energy density. Lithium-ion battery technology, has been quiet for 20 years without major technical innovations. A study of power battery car battery, experts say, the biggest obstacle is the limited power density lithium-ion battery, it can not quickly receive large amounts of energy or release. Tesla uses an upgraded version of Roadster3.0 had improved lithium battery, Tesla did not confirm whether or not to join the graphene. However, its performance has greatly improved, I am afraid only of graphene can do. The new and improved capacity 18650 lithium battery greatly increase the number of battery packs 6831 did not increase, but the total capacity of the battery pack from 53kWh increased to 70kWh. Japan to implement two lines parallel distribution of automotive batteries in battery technology, in addition to the development of Lithium batteries in the ordinary sense, they also studied fuel cell technology to replace with a special material graphene platinum as a catalyst, to produce the required hydrogen fuel cell vehicle fuel car battery, get a breakthrough. According to Li Yichun introduced a car battery to join two pieces of research currently divided on the overall graphene: one for application in traditional lithium batteries, the purpose is to improve and enhance the performance of lithium batteries, these batteries do not have disruptive effects; the second is based on graphene to create a new system of batteries, it is a new series, the performance is subversive, known as "super cell." China 2015 mass production of graphene promotion of new energy vehicles in China lithium battery for up to five years, but the effect is not ideal. According to the Ministry of Industry statistics show that 11 months of 2014, cumulative production of new energy vehicles 56700, and 2015 pure electric vehicles and plug-in hybrid car production and sales goals and strive to reach a total of 500,000 of the gap is huge.
