Specific　VO2　(B)　nanoflowers　and　their　composite　hybridized　with　graphene　nanoribbons　(GNRs)　are　prepared　using　a　moderate　H2C2O4　reductant　to　reduce　V2O5　with　the　molar　ratio　of　H2C2O4:V2O5　as　3:1.　The　discharge　specific　capacities　and　the　cycling　stabilities　of　the　VO2　(B)　cathode　material　for　lithium-ion　batteries　can　be　improved　by　graphenes　support.　In　particular,　GNRs　support　can　improve　the　dispersibility　and　the　electrical　conductivity　of　the　VO2　(B)　nanoflowers.　Thus,　VO2　(B)/GNRs　(32.2　wt%)　composite　exhibits　excellent　electrochemical　performance　with　the　high　specific　capacity　of　471.5　mA　h　g-1　and　the　preferable　cycling　stability.　©　2016　The　Royal　Society　of　Chemistry.
