But the large volume change of silicon during lithiation and delithiation and the resulting poor cyclability has prevented its commercial application. Herein, we report Si/Al multilayer thin film electrodes which are deposited on a Ni substrate by alternate sputtering of Si and Al at room temperature. Si/Al multilayer thin films are prepared using an RF magnetron sputtering method, and their potential use as anode materials for rechargeable lithium-ion batteries is investigated. The insertion of the Al layer into the Si layer improves the cycling performance. Si/Al multilayer thin films show an amorphous structure. The electrochemical characteristics of Si/Al multilayer film electrode can be controlled by the thickness, and number of stacked Si layers. Our prepared multilayer structures provided a promising research platform that may eventually lead to an optimized anode structure for advanced rechargeable lithium secondary batteries.
