APPLIED ELECTROCHEMISTRY AND CORROSION PROTECTION OF METALS - KINETICS OF ELECTRODE PROCESSES ON CADMIUM ELECTRODE OF A SEALED NICKEL-CADMIUM-ACCUMULATOR

The kinetics of electrode processes on cadmium electrode of an alkali accumulator related to the variations of concentration of cadmium spec ies in the near-electrode Layers of electrolyte under the primary curr ent-generating process as well as the mechanism of contamination of se paration materials under the conditions when an electrode is operated as a part of sealed accumulators are studied. The major factors that l ead to an increase in the concentration of cadmium species in the near -electrode layers and are mainly responsible for the penetration of ca dmium into the separation material, its reduction to metal under cycli ng and further interelectrode leakages and short cuts are determined.
