(LVO) was synthesized using sol-gel method and its electrochemical properties versus Li+/Li were studied. The influence of synthesis temperature on the structure properties including lattice parameters, crystallite size and mode vibration were investigated by X-ray powder diffraction and Raman spectroscopy.
