Fast Microwave Synthesis Lithium Vanadium Phosphate Using Peg as a Novel Carbon Source

Abstract:

The Li3V2(PO4)3/C cathode material is prepared by fast microwave synthesis route using PEG as carbon source. The samples were characterized by X-ray diffraction (XRD), galvanostatically charge/discharge test and electrochemical impedance spectroscopy (EIS). XRD result shows that the material was well crystallized and the structure was indexed as a monoclinic Li3V2(PO4)3/C. The electrochemical tests of material exhibit good cycling performance, which delivered a high initial discharge of 125.2 mAh g-1 at 0.2C and the retention of capacity was 92.4% after 50 cycles. From this study, the PEG-based microwave preparation method is regarded as a feasible route for the preparation of Li3V2(PO4)3/C cathode material.
