Comparison of various types of power lithium batteries

　　Power batteries are mainly considered based on their applications, mainly used in electric vehicles, electric bicycles, robots, power tools, etc.

　　Power batteries differ from ordinary batteries and have their own unique characteristics:

　　a. Series parallel connection of batteries

　　b. The battery has a large capacity

　　c. The discharge rate of the battery is relatively high (for hybrid and electric tools)

　　d. The safety requirements for batteries are relatively high

　　e. The working temperature range of the battery is wide

　　f. The battery has a long service life, generally requiring 5-10 years

　　Due to the particularity of power batteries, there are also certain differences in their processes and materials. According to the situation of positive electrode materials, they are mainly divided into lithium manganese oxide (LiMn2O4), ternary lithium (LiNixCoyMnzO2), lithium iron phosphate (LiFePO4), etc. Their voltage platform, energy density, price, safety, etc. all have certain differences, as shown in the comparison table below:
