摘　　要：分析了有关碱性密封蓄电池内气压问题的实验结果和结论 ,讨论了它们之间的差异及其产生的条件。指出有关在镉电极中添加银、碳等有助于氧复合的正面效果时应慎重引用“催化”的概念。本工作实验结果表明 ,在优化镉电极条件下 ,密封Cd/Ni实验电池的内气压在充电全过程中可能降至 0 0 2MPa以下 。The results of experiments and the point of view reported in some literatures about the problem of internal pressure in sealing alkaline accumulator were collected and some differences in them were analysed.It was indicated that it should be careful to use the conception of catalysis in respect to the positive effect of adding Ag and C into cadmium electrode for increasing oxygen recombination.At the same time,the results of the experiment showed that under the condition of an optimized structure of cadmium electrode,the internal pressure of the test sealing nickel cadmium battery tested could be minimized to lower than 0.02 MPa in all period of charge at 0.2 C .
