A series of xLiFePO4·yLi3V2(PO4)3 composites were systematically synthesized through solid state reactions by variations in the proportions of LiFePO4 and Li3V2(PO4)3. The properties of the prepared compounds were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM) and electrochemical measurements. The capacity of 162.7 mAh/g at 0.2 C rate was obtained with the relatively good cycle stability and good conductivity for 0.95LiFePO4·0.05Li3V2(PO4)3 due to more uniformed distributed and smaller particle sizes.
