Generally, the most powerful power batteries are lithium iron phosphate batteries, lithium manganate batteries, lithium cobaltate batteries, and ternary lithium batteries (ternary nickel cobalt manganese). The above -mentioned batteries have advantages and disadvantages, which are roughly summarized:

　　Lithium iron phosphate battery: long life, large charging and discharge rate, good safety, good high temperature, harmless elements, low cost. But low energy density and low vibration density (volume density).

　　Sanyuan lithium battery: high energy density and high vibration density. However, poor safety, poor high temperature resistance, poor life, high -power discharge difference, and toxic elements (the temperature increases sharply after the high power charging of the ternary lithium battery, and the release of oxygen after high temperature is extremely easy to burn).

　　Lithium manganate battery: high density and low cost. However, the high temperature resistance is poor, the temperature rises sharply after a long period of use, and the battery life is severe (such as the Nissan electric vehicle Leaf).
