▎ 摘　　要

Graphene modified Li3V2(PO4)(3)/C composites (Gr-LVPCs) are successfully synthesized through the rheological phase reaction method. The composite cathode material could deliver a high reversible capacity of 184.02 mAh g(-1) with discharge capacity of 141.42 mAh g(-1) after 100 charge/discharge cycles in the voltage range of 3.0-4.8 V at the current rate of 15 mA g(-1). Moreover, a high reversible capacity of 165.40 mAh g(-1) with stable cycling can also be obtained at a current density of 90 mA g-1. Those results suggest that graphene modification can be a powerful approach to improve the electrochemical performance of electrode materials, and Gr-LVPCs can serve as a very promising cathode material for rechargeable lithium batteries.
