摘要：

TiO2 array film fabricated by potentiostatic anodization of titanium is characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and charge-discharge measurements. The XRD results indicated that the TiO2 array is amorphous, and after calcination at 500 A degrees C, it has the anatase form. The pore size and wall thickness of TiO2 nanotube arrays synthesized at different anodization voltages are highly dependent on the applied voltage. The electrochemical performance of the prepared TiO2 nanotube array as an electrode material for lithium batteries was evaluated by galvanostatic charge-discharge measurement. The sample prepared at 20 V shows good cyclability but low discharge capacity of 180 mA h cm(-3), while the sample prepared at 80 V has the highest discharge capacity of 340 mA h cm(-3).
