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.Process for the preparation of a positive active material for an electrochemical generator based on manganese dioxide. We start with a manganese dioxide other than MnO2 beta, add an aqueous solution, and heat to a temperature equal to or higher than 100 degrees C for a time sufficient to obtain a variety of manganese dioxide whose maximum absorption infrared has a wave number between 530 cm-1 and 560 cm-1.
