摘　　要：通过在化成电解液中添加Cl-制备银电极,并对银电极进行了老化实验、扫描电子显微镜法(SEM)、DSC、含量及放电容量等性能的测试。测试结果表明,在化成电解液中添加Cl-不仅可以提高银电极的充电容量,而且使银电极具有较高的稳定性,从而使银电极老化后保持了较高的放电容量,提高了银电极的贮存性能,进而延长了锌银贮备电池的贮存寿命。The silver electrodes were prepared by adding Cl - into KOH electrolyte. The performance of silver electrodes was investigated by aging studies, SEM, DSC, AgO content and discharge capacity tests. The results show that adding Cl- into KOH electrolyte can not only enhance charge capacity of silver electrodes, but also improve the stability of the silver electrodes. The silver electrodes remains higher discharge capacity after aging, and the storage performance of silver electrodes increases, then storage life of silver-zinc reserve battery is prolonged.
