Abstract

Published by Elsevier Ltd. Anatase TiO2 nanowires (ATN) have been successfully synthesized via a topotactic chemical transformation. The asprepared ATN have an average diameter of around 30 nm with 1-2 micrometers in length. The electrochemical properties are investigated by constant current discharge/charge measurements. When charged at a rate of 150 mAg-1, the initial discharge capacity is about 400 mAh g-1, a reversible capacity of 168 mAh g-1 was retained after 100 charge-discharge cycles., This method is shown to be an effective and facile technique for improving the electrochemical performance for applications in rechargeable LIBs. The TiO2 nanowire was shown to be a promising anode material for lithium-ion batteries, especially on the fast charging and discharging performance.
