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.
