What are the classifications of lithium battery cathode materials?

The first category of lithium battery cathode material classification: lithium nickel oxide is mainly represented by lithium nickel oxide. The product characteristics are similar to nickel cobalt oxide, but the price is lower than that of nickel cobalt oxide because of its energy density. It can reach 274mAh/g. It is an ideal lithium battery cathode material for energy density, but its safety performance is too poor, not enough, and the number of cycles is relatively low. Therefore, manufacturers currently use lithium nickelate as lithium battery cathode materials not much. The second category: Lithium cobalt oxide Lithium cobalt oxide is mainly represented by lithium cobalt oxide. Due to the high price of the product, its monomer energy density can reach 274mAh/g, but its system energy density can only reach 138mAh/g, among which there are Five high, high energy density, high price, high power, high degree of commercialization, high cycle life, shortcomings are also obvious, and the price is too high. In the geographical location where cobalt salt is severely lacking in my country, cobalt salt must be imported. The third category: lithium titanium oxide The typical representative of lithium titanium oxide is lithium titanate. This product is mainly dominated by Zhuhai Yinlong. Its advantage is fast charging. This advantage can ignore its disadvantage, that is, the energy density is small. , It needs to be charged after running for a period of time. Fast charging is also more convenient. Another advantage is safety. The third advantage is that the number of cycles can reach 20,000 times, but its price is very high, so the price of a single cycle Can be pulled down. The fourth category: Nickel-cobalt multi-element oxides. This is what we often call multi-element oxides. At present, the most common ones are lithium nickel cobalt manganese oxide and lithium nickel cobalt aluminate. Among them, lithium nickel cobalt manganate is divided into nickel cobalt manganese acid. Lithium 111, Lithium Nickel Cobalt Manganese 523, Lithium Nickel Cobalt Manganese Oxide 622, Lithium Nickel Cobalt Manganese Oxide 811, but Lithium Nickel Cobalt Aluminate is rare, most of which are supplied by Panasonic to the American company Tesla for use. The ratio of nickel-cobalt-lithium aluminate is 0.8 to 0.15 to 0.05. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
