摘要
采用循环伏安、恒电流放电、阴极极化等方法,模拟研究了锌空气电池负极集流体在4mol/LKOH溶液中的电化学行为。结果表明:将传统的负极集流体表面镀铅,能有效地减小负极析氢,开路电位时集流体表面析氢电流密度降至1.0mA/cm2以下,使电化学性能得到改善。
The electrochemical behaviors of different negative current collectors for zinc-air battery in 4 mol/L KOH were investigated by cyclic voltammogram , galvanostatic discharge and cathodic polarization methods.The results showed that the hydrogen evolution of negative current collector decreased to 1.0 mA/cm2 at the open potential and the electrochemical behaviors were improved after lead electroplating on the surface of conventional negative current collectors.
