LiFePO_4 as the cathode active material for lithium ion battery

The iron-based cathode materials for lithium ion battery are promising due to its abundant resource, low cost and environment friendly characteristic. Among them, the olivine LiFePO4 is a potential active material for substituting LiCoO2. The research progresses on the electrochemical properties, structural characteristics, synthesizing methods, characterization methods and capacity loss of the olivine LiFePO4 are reviewed. The further research trend of the material is also discussed.
