What are the battery cells that can be selected when customizing lithium-ion battery packs?

The key to customizing lithium battery packs lies in the battery cells. At present, lithium-ion batteries are mainly divided into three types: lithium iron phosphate, lithium manganese oxide, and ternary lithium.

The advantages of lithium iron phosphate batteries lie in their functionality, safety, and lifespan, but their disadvantages are also quite prominent. The lifespan of lithium iron phosphate batteries is around 2000 cycles (laboratory data), but the battery pack has a short lifespan, generally around 500 cycles, and its low-temperature performance is poor. However, due to its high cost-effectiveness, most users who choose customized lithium-ion batteries will choose lithium iron phosphate as the battery cell.

Lithium manganese oxide, a type of battery cell that has been used for a long time in history, has high safety, especially strong resistance to overcharging. In addition, its material price is cheap, the production process requirements are not high, and the disadvantage is poor high-temperature performance.

The advantages of ternary lithium include structural stability, low cost, and activity. Compared with the other two types of lithium batteries, ternary lithium has significant shortcomings in safety performance, and after thermal runaway, it will produce a large amount of toxic gases, which is more dangerous.
