MANUFACTURING METHOD OF NICKEL-HYDROGEN STORAGE BATTERY AND METALLIC ALLOY FOR THE HYDROGEN STORAGE NEGATIVE ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide a nickel-hydrogen storage battery wherein the elevation of the inner pressure is restrained by the increase in the water repellency of the surface of an alloy for a hydrogen storage electrode and the improvement is made in hydrogen gas absorption capacity of alloy for the hydrogen storage alloy. SOLUTION: A hydrogen storage alloy negative electrode is manufactured by filling or coating support body with a paste whose main component is powder of an alloy for hydrogen storage, and a nickel-hydrogen storage battery is manufactured using a hydrogen storage alloy negative electrode wherein the surface of the hydrogen storage alloy negative electrode is coated with a solution in which a water repellant fluororesin is mixed with an organic solvent and the fluororesin is made to be in a dispersion state in the organic solvent, while giving ultrasonic refractions.
