The authors report results of a study of the influence of addition of tin on the performance of electrodes in silver-cadmium batteries. Based on experimental results, it is established that when tin is used as a stabilizing additive the anodic process on the silver oxide electrode is hindered, and this leads to gas evolution at an earlier stage. The cathodic process on the cadmium electrode is also hindered, probably as the result of aging of the stannate solutions formed and deposition of insoluble tin compounds on the surface of the cadmium electrode.
