Abstract

L'invention concerne un élément de pile alcalin. Selon l'invention, la couche supérieure 1 tournée vers l'électrode négative 7 de l'électrode positive est constituée par du bioxyde de manganèse gamma électrolytique dans lequel ont été incorporés en tant qu'additif de conduction de 6 à 16 % de poudre de graphite ayant un large spectre granulométrique. Sous celle-ci est disposée au moins une autre couche 2 contenant du bioxyde de manganèse gamma , de l'oxyde de mercure ou un oxyde d'argent monovalent, qui présente une plus grande densité apparente que la couche supérieure 1. Au-dessous de l'électrode positive est disposé un séparateur entourant au moins une membrane 4. Application aux piles pour montres électroniques, pour prothèses acoustiques, pour appareils électroniques portatifs et analogues.
