Using glucose as main carbon source and ascorbic acid (AA) as accessory carbon source, carbon coated lithium vanadium phosphate (LVP/C-AA) with high-rate performance was successfully synthesized by a solid-state reaction. The phases, morphologies, structures and electrochemical performance of samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), charging and discharging measurements, cyclic voltammogram (CV) testing and electrochemical impedance spectra (EIS). The results show that using ascorbic acid as accessory carbon source has no effect on the crystal structure of Li3V2(PO4)3, but enhances the high-rate performance. The LVP/C-AA electrode delivers an initial capacity as high as 162.4 mAh g-1 at 5 C, and shows an excellent capacity retention ration of 80.4% even after 100 cycles.
