Synthesis and electrochemical properties of Li3V2(PO4)3/MWCNTs composite cathodes

► The first study to apply MWCNTs for the synthesis of Li3V2(PO4)3 (LVP)/MWCNTs materials. ► Novel methods for the synthesis of LVP/MWCNTs by microwave assisted sol-gel method. ► The doping of MWCNTs can greatly improve the high rate dischargeability of LVP/MWCNTs electrode. ► The J0 is 2.92 mA cm−2, which is larger compared with the results of J0 reported by other articles.
