PURPOSE: To enhance charging efficiency at high temperature in spite of a small amount of additive, and lengthen life. CONSTITUTION: Nickel hydroxide powder, a small amount of calcium zincate powder, and cobalt hydroxide powder are mixed, then the mixture is kneaded together with carboxymethylcellulose to prepare slurry. The slurry is filled in a foamed nickel substrate, dried, pressed, then the nickel substrate is cut to produce a nickel paste electrode. A hydrogen storage alloy electrode serving as an anode and the nickel electrode are wound together with a nonwoven fabric separator so as to position the hydrogen storage alloy electrode in the outer periphery to form an electrode group. The electrode group is put into a cylindrical battery can, and 31 wt.% potassium hydroxide aqueous solution is poured into the can to manufacture a sealed nickel hydrogen storage battery. |
