摘　　要：VO2（B） nanosheets were prepared by a liquid-phase exfoliation from VO2（B） bulk.The lithium storage properties of VO2（B） nanosheets as capacity cathode materials for rechargeable lithium secondary batteries were investigated.It was found that the nanosheets with the thickness of several nanometers and width of tens of nanometer had a preferential growth direction along[001]orientation.By comparing with VO2（B） bulk,the VO2（B） nanosheets showed a higher initial discharge capacity and a slower capacity fading rate.The reasons for these phenomena were discussed and analyzed.VO2（B） nanosheets were prepared by a liquid-phase exfoliation from VO2（B） bulk.The lithium storage properties of VO2（B） nanosheets as capacity cathode materials for rechargeable lithium secondary batteries were investigated.It was found that the nanosheets with the thickness of several nanometers and width of tens of nanometer had a preferential growth direction along[001]orientation.By comparing with VO2（B） bulk,the VO2（B） nanosheets showed a higher initial discharge capacity and a slower capacity fading rate.The reasons for these phenomena were discussed and analyzed.
