Abstract

Well-dispersed graphene materials reduced by Ac under hydrothermal condition were used as conductive additives to improve intrisic disadvantage of promising LiFePO4 battery materials, which was synthesized at surface of graphene sheets. The as-prepared LiFePO4/graphene composites were characterized by X-ray powder diffraction (XRD), scan electron microscopy (SEM), electrochemical impedance spectroscopy (EIS) and galvanostatic charge-discharge tests. The results show that, compared with conventional LiFePO4 platelets, the composite deliver excellent electrochemical performances, due to flexible graphene-based porous conducting network. We believe that such a facile process will provide a new pathway for further enhancing its energy storage efficiency.
