VO_2(B) nanosheets were prepared by a liquid-phase exfoliation from VO_2(B) bulk.The lithium storage properties of VO_2(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 VO_2(B) bulk,the VO_2(B) nanosheets showed a higher initial discharge capacity and a slower capacity fading rate.The reasons for these phenomena were discussed and analyzed.
