A　novel　type　of　the　TiO2　(B)/C　composite　nanowire　was　developed　by　the　two-step　hydrothermal　synthesis,　followed　by　annealing　in　argon　atmosphere.　Various　factors　influencing　the　film　growth　were　evaluated.　The　microstructures　and　electrochemical　properties　of　the　nano-wire　were　characterized　with　X-ray　diffraction,　scanning　electron　microscopy,　and　transmission　electron　microscopy.　The　results　show　that　the　composite　nanowires　consist　of　the　TiO2　core　surrounded　by　amorphous　carbon　shell,　and　that　it　has　favorable　electrochemical　properties.　A　prototyped　Li-ion　battery　was　fabricated　with　the　TiO2　(B)/C　composite　nanowire　as　the　anode　material.　The　nanowires　display　excellent　cyclic　performance　and　rate　capacity.　For　example,　after　100　cycles　at　a　current　density　of　30　mAg-1,　its　reversible　capacity　was　found　to　be　560　mAhg-1　with　excellent　cycling　stability　and　the　rate　capacity　(200　mAhg-1,　when　cycled　at　750　mAg-1).　We　suggest　that　the　TiO2　(B)/C　composite　nanowire　be　a　potential　anode　material　for　Li-ion　battery.
