Evaluation of Pulsed Laser Deposited Li4Ti5O12 Thin Film Anodes by CV and EIS

摘要：

　　Li4Ti5O12 thin film anodes were prepared successfully using pulsed laser deposition technique.The thin films were characterized by X-ray diffraction and environmental scanning electron microscopy.The effects of thickness and scan rate on the electrochemical properties of Li4Ti5O12 thin film electrodes were discussed in detail.The thin film anodes deliver favorable capacity and excellent cycling performance.The discharge capacity maintains at 141 mAhg-1 after 20 cycles at 1C charge-discharge rate for the thin film anodes deposited for 20 minutes.The charge-transfer resistances were also investigated by electrochemical impedance spectroscopy.
