发明名称 VERFAHREN ZUR HERSTELLUNG NEGATIVER CADMIUMELEKTRODEN FUER GASDICHT VERSCHLOSSENE ALKALISCHE AKKUMULATORENZELLEN
摘要 Undesirable heavy metal peroxides formed during the continuous partial oxidation of cadmium electrodes made from a charged strip of material, by means of H2O2, to introduce a charge reserve prior to incorporation in a sealed alkaline battery cell, are removed by an immersion treatment in an alkaline hydroxide solution, with simultaneous desorption of oxygen and removal of the heat of hydrogenation. A subsequent boric acid immersion bath is used to neutralize introduced alkaline residues and to improve the stability of the strip during storage. The phenomena which accompany peroxide decomposition (intense evolution of heat and sputtering of electrolyte) in the completely assembled cell during the introduction of the electrolyte, and which interfere with the metering of the electrolyte, are thus avoided.
