Abstract

Anode gel et poudre de zinc pour piles alcalines au MnO2 . L'agent de gélification de l'anode est la méthylcellulose, à laquelle de la carboxyméthylcellulose peut être ajoutée, le cas échéant. La méthylcellulose permet d'éliminer la formation de courts-circuits internes. Domaine d'application : piles alcalines.
