Recent advances in synthesis and modification of phosphate-based cathode materials

Phosphate-based cathode materials such as LiFePO4(LFP) have been widely used in new energy vehicles and communication tools, due to their high stability and excellent electrochemical properties. Although many studies have demonstrated the advantages of phosphate-based cathode materials, there are still many challenges such as the low energy density, the criticism of the electrical conductivity, and the unsatisfactory low-temperature electrochemical performance to their further development. To address these challenges, many research efforts have been devoted to synthesizing and modifying phosphate-based cathode materials, and much progress has been made recently. As such, a summary of the latest research developments is needed to provide new insights into developing phosphate-based cathode materials. This review summarizes phosphate cathode materials in terms of their physicochemical properties, synthesis methods, and modifications.
