摘　　要：研究了碱性介质中电解液添加剂二乙胺和三乙胺的混合物对锌电极性能的影响。氧化锌溶解度测试和循环伏安测试的研究结果表明,添加二者的混合物可以降低ZnO在电解液中的溶解度,从而减缓锌电极的变形和枝晶;添加合适比例的二者混合物可以提高锌电极的循环稳定性。当添加0.3%wt二乙胺+0.3%wt三乙胺时效果最好。The influences of adding the mixture of diethylamine and triethylamine into alkaline electrolyte on the zinc electrode were studied.The solubility of ZnO and cyclic voltammetry curves showed that the mixture of diethylamine and triethylamine could decrease the solubility of ZnO therefore decreasing the deformation and restraining the dendrites.The proper mixing of diethylamine and tri-ethylamine could improve the cyclic stability of zinc electrode.The effect was the best when add 0.3%wt（C2H5）2NH ＋0.3%wt（C2H5）3N.
