采用线性扫描伏安法和电位阶跃法，研究了锂离子在铝电极上的电极过程机理．结果表明锂离子在铝电极上沉积形成α固熔体时，电极过程受锂原子向铝电极中的扩散速度控制．当形成β锂铝合金时，存在成核极化现象，成核过程为瞬间成核过程，初期电极过程受形成β锂铝合金的速度控制，一定时间后受锂原子通过β锂铝合金层的扩散速度控制．β锂铝合金阳极有极限充电电压和极限电流． The linear scanning voltammetry and potential step method were used to study the electrode process of lithium ion on aluminum electrode. The results show that when lithium ions are deposited on the aluminum electrode to form αsolid melt, the electrode process is controlled by the diffusion rate of lithium atoms into the aluminum electrode. When the formation of β-lithium-aluminum alloy, there is the phenomenon of nucleation polarization, the nucleation process for the instant nucleation process, the initial electrode process by the formation of β-lithium-aluminum alloy speed control, after a certain period of time by the lithium atoms by lithium aluminum Alloy layer diffusion rate control. β  lithium aluminum alloy anode has a limit charging voltage and limiting current.
