Abstract
Procédé de préparation d'une matière active positive pour générateur électrochimique à base de dioxyde de manganèse. On part d'un dioxyde de manganèse autre que MnO2 beta, on ajoute une solution aqueuse, et on chauffe à une température égale ou supérieure à 100 degrés C pendant un temps suffisant pour obtenir une variété de bioxyde de manganèse dont le maximum d'absorption infrarouge ait un nombre d'onde compris entre 530 cm-1 et 560 cm-1.
