密封低压镍镉电池

Sealed Nickel Cadmium Cells of Low Pressure Structure

为实现密封镍镉电池低压化,本论文研究了各种类型的镉电极。纤维镍正极采用电化学浸渍法制备,并将相当氢氧化镍正极50％容量的LaNi_5基贮氢合金加入到镉负极中以考察其对氧复合和氢吸收的能力。另采用不同结构镉负极组装其它两种类型的密封电池,以使电池保持较低内压力。

Various cadmium electrodes were investigated in order to depressurize the sealed nickel cadmium cells. The fibrous nickel positives were made by electrochemical impregnation. LaNi5 - based hydrogen storage alloy powders were added to the cadmium electrodes in order to examine the ability of the sealed cell on the oxygen recombination and hydrogen absorption. The cadmium negative electrodes of different structure were applied to prepare the other two kinds of the sealed cells in order to keep them in a low pressure level.
