摘　　要：研究了碱性介质中电解液添加剂二乙醇胺[(C2H4OH)2NH]和三乙醇胺[(C2H4OH)3N]的混合物对锌电极的枝晶和变形的影响。电位阶跃法得出的电流-时间曲线和氧化锌溶解度测试的研究结果表明,添加剂可以降低恒电位阴极极化中反应电流的回升值,降低氧化锌在电解液中的溶解度,从而减缓锌电极的变形和枝晶。当添加0.3%wt二乙醇胺+0.1%wt三乙醇胺时,锌电极综合性能优良,有望投入实际应用。The influences of adding the mixture of diethylamine[（C2H4OH）2NH] and triethylamine[（C2H4OH）3N] into alkaline electrolyte to the dendrite and deformation of zinc electrode were studied.The result of the research,focusing on the current-time curves using potentiostatic method and solubility of ZnO,showed that the mixture of diethylamine and triethylamine could decrease the current rally value in potentiostatic method and decrease the solubility of ZnO,so could decrease the deformation and restrain the dendrites.The general effect was the best when adding 0.3%[（C2H4OH）2NH] ＋ 0.1%[（C2H4OH）3N],and it could be expected to be put into practice.
