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.

Carbon-coated lithium vanadium phosphate cathode materials were successfully prepared via an ultra-fast microwave irradiation route in 5 min with using activated carbon as the microwave adsorbent. We aimed to utilize this ultra-fast and facile route to shorten the synthesis procedure for obtaining Li3V2(PO4)3/C cathode material with superior rate capability. To characterize the intrinsic crystal structure and exterior architecture morphology of targeted material, X-ray diffraction pattern (XRD), scanning electron microscopy (SEM) in combined with transmission electron microscopy (TEM) were applied in experiment. The role of microwave irradiation treatment time in affecting the crystalline structure and related lithium-storage electrochemical performance is also investigated in detail. For the optimal Li3V2(PO4)3/C material, it delivered a specific discharge capacity of 110.1 mAh g−1 at a 0.2 C charging/discharging rate while hold a superior cycling stability over 50 cycles when tested at a 1 C rate. The ultra-fast synthesis route should pave a new way to save the energy in the preparation of phosphate-based electroactive cathode material.
