Method for oxidising negative metal cadmium electrodes for alkaline electrochemical generators; negative oxidised electrodes obtained by this method; method for forming alkaline electrochemical generators provided with such negative electrodes; and generators thus formed

摘要

The oxidation method consists in plunging the electrode of cadmium metal in a hydrogen peroxide solution, optionally after treatment with an aqueous ammonia solution and after drying. Figure 1 represents the X-ray diffraction spectrum of a deposition of cadmium oxidised by hydrogen peroxide (cadmium peaks Cd and cadmium peroxide and cadmium hydroxide peaks P). IMAGE
