Abstract

La présente invention concerne la réalisation de piles électrochimiques et plus précisément une conception nouvelle d'une électrode positive au bioxyde de manganèse. L'objet de ce brevet consiste en la réalisation d'une électrode positive telle que la masse positive constituée par un mélange de bioxyde de manganèse et de noir de carbone, qui entoure le collecteur de courant positif, notamment dans les piles de type Leclanché, soit remplacée par un feutre de carbone servant de support au bioxyde de manganèse. Cette conception nouvelle permet de pallier les inconvénients présentés par le procédé couramment utilisé.
