•Novel and simple synthetic routes for LiFePO4/graphene.•LiFePO4/graphene delivers high capacity of 160 mAh g−1 at 0.1C.•Exciting electrochemical performance due to coated graphene was observed.
LiFePO4/graphene (LiFePO4/G) cathode with exciting electrochemical performance was successfully synthesized by liquid phase method. LiFePO4 nanoparticles wrapped with multi-layered grapheme can be fabricated in a short time. This method did not need external heating source. Heat generated by chemical reaction conduct the process and removed the solvent simultaneously. The LiFePO4/G were analyzed by X-ray diffraction (XRD) analysis, scanning electron microscope (SEM), transmission electron microscopy (TEM), magnetic properties analysis and electrochemical performance tests. The LiFePO4/G delivered a capacity of 160 mAh g−1 at 0.1C and could tolerate various dis-charge currents with a capacity retention rate of 99.8%, 99.2%, 99.0%, 98.6%, 97.3% and 95.0% after stepwise under 5C, 10C, 15C, 20C, 25C and 30C, respectively.
