| 摘要 | In this work, mixed (electron and ion) conducting LiFePO4/graphene composites have been prepared through a facile hydrothermal route followed by heat treatment. It was found that the LiFePO4 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 LiFePO4. The LiFePO4/graphene (92:8 wt.) composites exhibited a discharge capacity of 160.3 mAh g(-1) at 0.1 C and 81.5 mAh g(-1) at 10 C, respectively. The comparative investigation on LiFePO4/graphene composites and LiFePO4 proved that establishing a mixed conducting network with graphene has a potential to enhance the specific capacity and rate capability of LiFePO4.
