摘 要: 利用线性扫描伏安法详细研究了锂离子在铝电极上的电极过程机理。锂在铝电极上的电极过程受锂在β-LiAl合金相中的扩散控制，扩散是通过空穴机制完成的。为电化学方法制备锂铝合金阳极提供了极限参考电压和电流，并计算了β-LiAl合金形成的活化能。

Abstract:The deposition mechanism of lithium on aluminium electrode was studied by using linear sweep voltammetry. Results showed that the process of lithium depositing on aluminium electrode is controlled by the diffusion of lithium in β-LiAl alloy, which is achieved through the atom vacancies. The limiting reference potential and current were given for preparing LiAl alloy electrodes, and the activation energy of the formation of β-LiAl alloy was calculated.
