| Abstract: | Lithium iron phosphate （LiFePO4） has become one of the research hotspots because of its advantages, high theoretical capacity, voltage stability and so on. However, its lower electron conductivity and slower lithium ion diffusion speed entirely due to the defect structure. This article started with LiFePO4 crystal structure and charge-discharge mechanism, analyzed the reasons for its weakness, and summarized the progress of modification methods of LiFePO4 cathode material, and its research progress. |
