High rate cathode Li3V2(PO4)(3)/C with an excellent electrochemical performance has been successfully synthesized via an in-situ copolymerization method. The synthesized Li3V2(PO4)(3)/C composite exhibits an extraordinary reversible discharge capacity of 103.1 mAh g(-1) at 50 C discharge rate. In addition, there are no obvious capability fade after 100 cycles. The carbon from pyrolysis of polyacrylamide obtained from the in-situ copolymerization reaction is believed acting a critical role in acquiring such high performances. (C) 2013 Elsevier B.V.
