Abstract: The Li3V2(PO4)3/C composite cathode material is synthesized via a simple carbothermal reduction reaction route using polyvinyl alcohol (PVA) as both reduction agent and carbon source. The XRD pattern shows that the as-prepared Li3V2(PO4)3/C composite has a monoclinic structure with space group P21/n. The Raman spectrum reveals that the residual carbon contains much amounts of sp2-type carbon. The sp2-type carbon can largely enhance the electronic conductivity of the Li3V2(PO4)3/C composite. This cathode material exhibits excellent electrochemical performance. The initial discharge capacities are as high as 121.4 mAh/g (0.3 C), 110.8 mAh/g (1 C), 103.2 mAh/g (3 C) and 95.3 mAh/g (5 C). The cycle ability of this material is perfect.
