Abstract

The effect of annealing on TiO₂ nanotube arrays as anode for lithium ion batteries by X-ray diffraction, field emission scanning electron microscopy, cyclic voltammetry, galvanostatic charge-discharge testing, and electrochemical impedance spectroscopy was investigated. The crystalline structure of TiO₂ nanotube can be changed by controlling the annealing temperature and the crystallization also has considerable effect on electrochemical performance. Amorphous TiO₂ annealed at 250 °C shows the highest discharge capacity in coin cell tests with a discharge capacity of about 67 μAh cm^-2 and good cycling stability during 50 charge-discharge cycles. The electrochemical impedance spectroscopy results show the smallest resistance compared to the other samples. © 2011 American Scientific Publishers.
