Sodium-ion　batteries　(SIBs)　have　recently　attracted　intensive　attentions　as　a　potential　alternative　to　LIBs　for　large-scale　energy　storage　applications.　However,　one　of　the　major　challenges　to　the　commercialization　of　SIBs　is　the　limited　choice　of　anode　materials　that　can　offer　high　rate　capability.　In　this　regard,　we　report　intertwined　Cu3V2O7(OH)(2)center　dot　2H(2)O　nanowires/carbon　fibers　composite,　fabricated　by　a　facile　hydrothermal　method,　as　the　anode　material　for　SIBs.　It　shows　s　a　highly　reversible　Na-ion　storage　capacity　of　287.4　mAh　g(-1)　after　50　cycles　at　a　large　current　density　of　0.5　A　g(-1),　and　excellent　rate　performance　of　delivering　206.5　and　127.7　mAh　g(-1)　after　50　cycles　at　high　current　densities　of　5　and　10　A　g(-1),　respectively.　The　promising　performance　is　ascribed　to　both　the　crystal　structure　of　Cu3V2O7(OH)(2)center　dot　2H(2)O　with　a　large　interlayer　spacing,　and　unique　intertwined　network　morphology　of　CuVOH-NWs/CFs　composite　in　which　CuVOH-NWs　and　CFs　synergistically　functioned.　This　work　will　pave　a　way　to　develop　more　metal　vanadates　materials　as　anodes　for　high-performance　SIBs.　2015　Elsevier　B.V.　All　rights　reserved.
