摘要
在653~693K温度下电解LiCl-KCl体系制备金属锂,分别研究电解温度、电流密度、电解质比例以及阴阳极间距对金属锂电解电流效率的影响。最佳电解温度为653~673K、LiCl-KCl电解质最佳质量比为LiCl∶KCl=50%∶50%,同时较大的电流密度与极距对电流效率更有利。
Lithium metal was produced from LiCl-KCl molten salt at 653-693 Kby molten salt electrolysis.Effects of electrolysis temperature,current density,electrolyte ratio,and inter-electrode distance on current efficiency of lithium metal electrolysis are analyzed.The results show that the optimum electrolysis temperature is 653-673 K,the optimum mass ratio of LiCl-KCl electrolyte is 50%∶50%,and higher current density and pole distance is beneficial to current efficiency.
