▎ 摘  要

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 nrn was prepared by a one-pot and template-free in situ hydro [thermal 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 even at 20C (1C = 400 mAh g(-1)). After 500 cycles at 10C there is no evident capacity fading.
