Comparison of different lithium batteries in Electric Car

1. In terms of safety performance, lithium iron phosphate batteries are the best, and the future cost reduction space is relatively large. The high temperature performance of lithium manganate batteries is relatively poor, and the application of high temperature in electric vehicles is a common problem. Lithium cobalt oxide batteries are mainly a safety issue and are not suitable for electric vehicles.

2.The positive and negative materials used in liquid lithium-ion batteries and polymer lithium-ion batteries are the same as those used in liquid lithium-ion batteries, and the working principles of the batteries are basically the same. Their main difference lies in the difference in electrolytes. Li-ion batteries use liquid electrolytes, while polymer lithium-ion batteries use polymer electrolytes instead.
