Li3V2(PO4)3 cathode material was prepared by a carbon-thermal reduction (CTR) process. V2O5,LiOH-H2O,NH4H2PO4 and C were used as starting materials to synthesize Li3V2(PO4)3 by sintering the mixture at 800 ℃ for 24 h. The property of the Li3V2(PO4)3 sample was investigated by X-ray diffraction (XRD),scanning electron microscopy (SEM) and electrochemical measurement. The results show that the Li3V2(PO4)3 sample has the same monoclinic structure as the Li3V2(PO4)3 sample synthesized by hydrogen reduction method. The particle size is about 1.5 ìm together with homogenous distribution. The initial discharge capacity of Li3V2(PO4)3 powder is 120 mA·h·g-1 at the rate of 0.1C,and the capacity retains 112 mA·h·g-1 after 30 cycles.
