Characterizations of the electrode/electrolyte interfacial properties of carbon coated Li3V2(PO4)3 cathode material in LiPF6 based electrolyte

► Li3V2(PO4)3/C cathode material that prepared by the CTR method shows excellent electrochemical performance over 300 cycles. ► The formation of SEI film is confirmed by HRTEM, FTIR and EIS analysis. ► A proper amount of SEI film is helpful for the electrochemical performance of Li3V2(PO4)3.
