A　novel　type　of　the　TiO　2　(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　TiO　2　core　surrounded　by　amorphous　carbon　shell,　and　that　it　has　favorable　electrochemical　properties.　A　prototyped　Li-ion　battery　was　fabricated　with　the　TiO　2　(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　TiO　2　(B)/C　composite　nanowire　be　a　potential　anode　material　for　Li-ion　battery.
