摘要： 采用电流-时间曲线研究了6-硝基苯并咪唑、苯并咪唑和Pb2+在KOH（4 mol/L）溶液中对锌枝晶的影响。 结果表明，6-硝基苯并咪唑、苯并咪唑以及Pb2+能有效抑制锌枝晶的形成，从而提高锌电极的充电性能；当0.05 g/L Pb2+分别与6-硝基苯并咪唑和苯并咪唑在阴极过电位η=-200 mV进行充电实验时，具有较高的充电效率并能有效的抑制锌枝晶的生长。

关键词: 锌枝晶, Pb2+, 6-硝基苯并咪唑, 苯并咪唑, 过电位

Abstract: The influences of 6-nitrobenzimidazole, benzimidazole and Pb2+ on zinc dendrite in KOH solution(4 mol/L) were investigated by means of current-time technique. The results showed that 6-nitrobenzimidazole, benzimidazole and Pb2+ could effectively inhibit the formation of zinc dendrites, and enhance the charging capacity of zinc electrode. It showed a high charging efficiency and effective inhibition to the growth of zinc dendrites when the charging was performed at a cathodic overpotential η=-200 mV in 0.05 g/L Pb2+ alkaline solution with the addition of 6-nitrobenzimidazole or benzimidazole.

Key words: Zinc dendrite, Pb2+, 6-Nitrobenzimidazole, Benzimidazole, Overpotential
