PROCESS FOR PRODUCING HYDROGEN-OCCLUSION ALLOY ELECTRODE OF ALKALINE STORAGE BATTERY

摘要

An object of the present invention is to provide a method for producing a hydrogen-absorbing alloy electrode for an alkaline storage battery which is efficient and effective enough to improve the performance of the battery. The method according to the present invention comprises the steps of: preparing a powdery hydrogen-absorbing alloy; and washing the powdery hydrogen-absorbing alloy with a strong acid solution and then with a weak acid solution having a higher pH value than the strong acid solution for a two-stage acid treatment.
