Sn/Cu　nanowire　composite　film　was　electrodeposited　on　copper　foil　substrates　and　used　as　an　anode　material　for　lithium-ion　batteries.　The　structure　of　the　obtained　composite　film　anode　was　characterized　by　X-ray　diffraction　(XRD)　and　scanning　electron　microscopy　(SEM).　The　electrochemical　performance　was　evaluated　by　cyclic　voltammetry,　galvanostatic　cycling　and　impedance　spectroscopy.　It　was　found　that　the　Sn/Cu　nanowire　composite　film　anode　showed　a　better　cycle　stability　than　Sn　film　anode,　whereas　the　Sn/CNT　composite　film　anode　indicated　poor　capacity　retention.　It　could　be　deduced　that　copper　nanowire　reinforced　the　Sn　film　anode　due　to　the　better　wetting　property　of　Sn　on　the　surface　of　copper　and　reduced　the　loss　of　electric　contact　among　tin　particles　in　the　Sn/Cu　nanowire　composite　film　anode.　(C)　2010　Elsevier　Ltd.　All　rights　reserved.
