WO2 modified LiFePO4/C cathode materials with improved electrochemical performance synthesized by in-situ synthesis method

WO2 modified LiFePO4/C cathode materials were synthesized by the in-situ synthesis method. WO2 can sufficiently coat on the particles surface of LiFePO4 and does not alter LiFePO4 crystal structure, the existence of WO2 as a conductive oxide improves the discharge specific capability and apparent lithium ion diffusion coefficient of cathode materials and decreases charge transfer resistance.
