摘　　要：本文研究了几种金属氧化物对镉电极活性物质利用率以及对密封Cd/Ni蓄电池荷电保持能力的影响。结果表明,镉电极中添加MgO、ZnO和Fe_2O_3可提高活性物质利用率;添加o_2O_3则显著降低活性物质利用率。MgO、In_2O_3和ZnO的添加,提高了密封Cd/Ni蓄电池的荷电保持能力;Co_2O_3和Fe_2O_3的添加,降低了其荷电保持能力。最后,探讨了MgO和ZnO在镐电极中的适宜添加量。Several kinds of metal oxides were investigated as additives for pasted cadmium electrodes. It was found that some additives such as MgO,ZnO and Fe2O3 ware effective for improving the utilization of cadmium active material. whereas Co2O3 has a contrary effect. The addition of MgO,In2O3 and ZnO improved the retention of charge of the sealed Cd/Ni batteries. Co2O3 and Fe2O3 lowed the retention of charge. Finally,the appropriate amount of MgO and ZnO added to cadmium electrodes was discussed.
