Under China's relevant policies, the focus on civilian vehicles has shifted from fuel vehicles to new energy vehicles. However, there are a variety of choices for the positive electrode materials of battery systems, and different positive electrodes have different advantages. This paper investigates three cathode materials used in new energy vehicles, describes their preparation methods, and compares their performances. The results are that the highest first discharge specific capacity is for a lithium-ion battery prepared from LiNi0.94Co 0.04Al 0.02(OH)2 as the cathode material, and the highest first coulomb efficiency and cycle capacity retention is for a lithium iron phosphate battery prepared from a LiFePO4/C composite. The purpose of studying the three materials in this paper is to understand the advantages and disadvantages of the batteries used in the current new energy electric vehicles, and in the follow-up research, try to further improve their characteristics according to these their battery capacity and thermal stability.
