Title:
SINTERED CATHODE PLATE FOR ALKALINE STORAGE BATTERY AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JPH076760
Kind Code:
A
Abstract:
PURPOSE: To provide an alkaline storage battery with high capacity and high charging performance in a high temperature atmosphere by improving a sintered cathode plate.
CONSTITUTION: Nickel hydroxide is densely filled (2.4g/cm2) in a nickel powder sintered substrate (porosity: 82%) in an impregnation process. Paste prepared by kneading cadmium oxide, methylcellulose (binder), and water is applied to the surface of the electrode plate filled with nickel hydroxide to form a cadmium oxide coated layer. The weight ratio of nickel and cadmium in the cathode plate is 95:5.
