The MoO2 modified LiFePO4/C cathode materials were synthesized by in situ synthesis method.
The existence of MoO2 decreases the particles size and increases the tap density of cathode materials.
MoO2 can sufficiently coat on the surface of LiFePO4/C cathode materials.
The existence of MoO2 enhanced electrochemical performance of LiFePO4/C cathode materials.
