Topotactically Synthesized TiO2 Nanowires as Promising Anode Materials for High-performance Lithium-ion Batteries

AbstractAnatase TiO2 nanowires (ATN) have been successfully synthesized via a topotactic chemical transformation. The as-prepared ATN have an average diameter of around 30nm 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
