Natural graphite treated by mechanical activation can be directly applied to the preparation of Li3V2(PO4)(3). The carbon-coated Li3V2(PO4)(3) with monoclinic structure was successfully synthesized by using natural graphite as carbon source and reducing agent. The amount of activated graphite is optimized by X-ray diffraction, scanning electron microscope, transmission electron microscope, Raman spectrum, galvanostatic charge/discharge measurements, cyclic voltammetry, and electrochemical impedance spectroscopy tests. Our results show that Li3V2(PO4)(3) (LVP)-10G exhibits the highest initial discharge capacity of 189 mAh g(-1) at 0.1 C and 162.9 mAh g(-1) at 1 C in the voltage range of 3.0-4.8 V. Therefore, natural graphite is a promising carbon source for LVP cathode material in lithium ion batteries.
