In this work, mixed (electron and ion) conducting LiFePO 4 /graphene composites have been prepared through a facile hydrothermal route followed by heat treatment. It was found that the LiFePO 4 particles adhered to the surface of graphene and/or embedded in the graphene nanosheets. As a result, an effective three-dimensional conducting network was formed by bridging graphene nanosheets, which can facilitate electron transport effectively and thus improve the kinetics and rate performance of LiFePO 4 . The LiFePO 4 /graphene (92:8wt.) composites exhibited a discharge capacity of 160.3mAh g −1 at 0.1C and 81.5mAh g −1 at 10C, respectively. The comparative investigation on LiFePO 4 /graphene composites and LiFePO 4 proved that establishing a mixed conducting network with graphene has a potential to enhance the specific capacity and rate capability of LiFePO 4 .
