POSITIVE ELECTRODE PLATE FOR ALKALINE STORAGE BATTERY

摘要

PURPOSE:To provide a positive electrode plate for alkaline storage battery with high energy density and good lifetime characteristic by lessening the adding amount of cobalt compound. CONSTITUTION:A compound layer 4 containing cobalt compound re-educed in the from of cobalt oxy-hydroxide is provided over the surface of an active material 3 to form an active material layer 2. A hydrophilic organic substance film 6 is formed over the surface of this active material layer 2. This permits lessning the adding amount of cobalt compound because the hydrophilic organic substance film 6 prevents the dissolved cobalt ions from dispersing.
