Abstract
A gelled anode for an alkaline electrochemical cell contains zinc-based particles, an alkaline electrolyte, a gelling agent, and two or more additives selected from the group consisting of an alkali metal hydroxide, an organic phosphate ester surfactant, a metal oxide, and tin, which as reduced cell gassing properties relative to cells lacking such additives.
