Title:
POSITIVE ELECTRODE PLATE FOR ALKALINE STORAGE BATTERY
Document Type and Number:
Japanese Patent JPH05151962
Kind Code:
A
Abstract:
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.
