Alkaline battery

摘要

A method for producing a gel form negative electrode of an alkaline battery with avoiding mercury enables uniform dispersion of zinc or zinc alloy powder and an effective metal which can be one or more of oxide or hydroxide of indium, lead, gallium, bismuth, by stirring for substantially reduced period. The method employs dry mixing of the zinc or zinc alloy powder and the effective metal in advance of mixing with a gel form alkaline electrolyte. Also, in order to obtain satisfactorily high vibration strength and impact resistance, fiber material can be added to the gel form negative electrode. The fiber material may be selected among rayon, vinylon, acryl, vinyon, polyamide, polypropylene, polyethylene, mercerized pulp, linter pulp.
