ALKALINE CELL WITH IMPROVED DISCHARGE EFFICIENCY

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...

Summary: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. Une anode gélifiée d'une pile électrochimique alcaline contient des particules à base de zinc, un électrolyte alcalin, un agent gélifiant, et deux additifs ou plus choisis dans le groupe constitué par un hydroxyde de métal alcalin, un tensio-actif ester phosphate organique, un oxyde métallique, et l'étain, qui présente des propriétés de dégagement gazeux de pile réduites par rapport à des piles ne présentant pas de tels additifs.
