Titanate nanotube prepared by a simple one-step hydrothermal reaction through TiO2 powders and alkaline solution has been widely studied owing to its enhanced rate capability and large discharge/charge capacity for lithium intercalation and extraction.In this study,titanate nanotube has been synthesized using TiO2.nH2O obtained through hydrolysis method as titanium source.The as-synthesized titanate nanotube exhibits an initial discharge capacity of 396.3 mAh/g and still keeps a stable cycling discharge capacity of 150 mAh/g after 200 cycles at a current density of 50 mA/g with the coulombic efficiency of about 100%,which shows more outstanding electrochemical properties than that synthesized from TiO2 powders.The role of H2O in TiO2.nH2O and electrochemical properties have been investigated in details.The results show that the assynthesized titanate nanotube can be used as a promising candidate as anode material for Li-ion batteries.
