摘　　要：研究了不同电解液种类、不同添加剂对电沉积锌电极性能的影响,考察了电沉积锌电极的大功率工作性能。通过实验表明:采用ZnO饱和密度为1.25g·cm-3的KOH水溶液作为电解质溶液,选用添加剂Ⅰ,当电沉积电流密度为100mA·cm-2时,电沉积出的锌电极可以在大功率锌银蓄电池中应用。实验电池以240mA·cm-2放电,循环7周期,活性物质利用率达到54%。The effect of various additives and electrolytes on morphology of electrodeposited zinc were studied by SEM. Electrodeposited zinc electrodes were charged and discharged in high power battery. It was found that the zinc electrodes, which were electrodeposited in 1.25 g·cm^-3 KOH electrolyte with additive Ⅰ under 100 mA· cm^-2 ,were discharged 7 cycles in 240 mA· cm^-2, and its utilization ratio reached 54%.
