Title (EN) IMPROVED MANGANESE DIOXIDE FOR ALKALINE CELLS
(FR) BIOXYDE DE MANGANESE AMELIORE POUR PILES ALCALINES
Abstract: front page image
(EN)Particulate Mn02, having simultaneously a micropore surface area greater than 8.0 m2/g, desirably between about 8.0 and 13 m2 /g and BET surface area of between about 20 and 31 m2/g within the context of an Mn02 having a total intraparticle porosity of between about 0.035 cm3/g and 0.06 cm3/g produces enhanced performance when employed as cathode active material in an electrochemical cell, particularly an alkaline cell. The average pore radius of the meso and macro pores within the Mn02 (meso-macro pore radius) is desirably greater than 32 Angstrom.
(FR)L'invention concerne du Mn02 particulaire, comportant la fois une aire spécifique microporeuse supérieure à 8,0 m2/g, de préférence entre environ 8,0 et 13 m2/g, et une aire spécifique BET comprise entre environ 20 et 31 m2/g dans le cas d'un Mn02 à porosité intraparticulaire totale comprise entre environ 0,035 cm3/g et 0,06 cm3/g. Ce manganèse présente un rendement amélioré lorsqu'il est utilisé comme matériau actif de cathode dans une pile électrochimique, en particulier une pile alcaline. Le rayon moyen des pores méso et macro du Mn02 (rayon de pores méso-macro) est préférablement supérieur à 32 Angstrom.
