Abstract
A gel form negative electrode of an alkaline battery is produced without mercury and enables uniform dispersion of zinc or zinc alloy powder and an effective metal which can be one or more of an oxide or hydroxide of indium, lead, gallium, bismuth. The zinc or zinc alloy powder and the effective metal are drymixed in advance of mixing with a gel form alkaline electrolyte. 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.
