Abstract


  • To explore good anode materials of high safety, high

    reversible capacity, good cycling, and excellent rate capability, a Li3VO4

    microbox with wall thickness of 40 nm was prepared by a one-pot and

    template-free in situ hydrothermal method. In addition, its composite with

    graphene nanosheets of about six layers of graphene was achieved. Both of

    them, especially the Li3VO4/graphene nanosheets composite, show superior

    electrochemical performance to the formerly reported vanadium-based

    anode materials. The composite shows a reversible capacity of 223 mAh g−1

    even at 20C (1C = 400 mAh g−1). After 500 cycles at 10C there is no evident

    capacity fading.
