What are the common classifications of power lithium-ion batteries?

Generally speaking, the most important power lithium-ion batteries are lithium iron phosphate batteries, lithium manganese oxide batteries, lithium cobalt oxide batteries, and ternary lithium batteries (ternary nickel cobalt manganese). The above types of batteries have their advantages and disadvantages, which can be roughly summed up as: Lithium iron phosphate: Advantages: long life, high charge and discharge rate, good safety, good high temperature performance, harmless elements, and low cost. Disadvantages: low energy density, low tap density (bulk density). Ternary lithium: advantages: high energy density, high tap density. Disadvantages: poor safety, poor high temperature resistance, poor life, poor high-power discharge, and toxic elements (the temperature rises sharply after high-power charging and discharging of the ternary lithium battery, and the release of oxygen after high temperature is very easy to burn). Lithium manganese oxide: advantages: high tap density and low cost. Disadvantages: poor high temperature resistance, the temperature rises sharply after long-term use of lithium manganate, and the battery life is seriously attenuated (such as the Nissan electric car LEAF). Lithium cobalt oxide: usually used in 3C products, with extremely poor safety and not suitable for power lithium-ion batteries. In theory, the battery we want should have high energy density, high volume density, good safety, high temperature and low temperature resistance, long cycle life, non-toxic and harmless, high-power charging and discharging, integrating all the advantages and low cost. But there is no such battery at present, so it is necessary to choose between the advantages and disadvantages of different types of batteries. Moreover, different electric vehicles have different requirements for batteries. Therefore, only a long-term judgment on electric vehicles can help us correctly judge the choice of battery route.
