Abstract

Porous N-doped carbon stabilized Li3V2(PO4)3 particles are prepared by a modified sol–gel method. Both the in situ doping of nitrogen and the formation of porous structure can be attributed to the addition of dicyandiamide in the sol–gel process. The composite material exhibits a high discharge capacity of 114.7 mA h g−1 at 1 C in the voltage range of 3–4.3 V after 600 cycles. Even at a high rate of 5 C, the discharge capacity of 90.5 mA h g−1 is achieved after 600 cycles. The superior electrochemical performance mainly benefits from the porous and nitrogen doped carbon.
