Title
(EN) ALKALI METAL OR ALKALINE EARTH METAL COMPOUND ADDITIVE FOR MANGANESE DIOXIDE-CONTAINING NONAQUEOUS CELLS
(FR) ADDITIF COMPOSE DE METAL ALCALIN OU DE METAL ALCALINO-TERREUX POUR CELLULES NON AQUEUSES CONTENANT DU DIOXYDE DE MANGANESE
Abstract
(EN)
A nonaqueous cell employing a manganese dioxide-containing solid cathode having a minor amount of an alkali metal or an alkaline earth metal additive such as Li2SiO3, Li2B4O7, Li2MoO4, Li3PO4 or Li2WO4 to suppress the build-up of internal impedance in the cell during storage and discharge that may occur with electrolyte degradation.
(FR)
Cellules non aqueuses utilisant une cathode solide contenant du dioxyde de manganèse, possédant une faible quantité d'un additif à base de métal alcalin ou d'un métal alcalino-terreux tel que Li2SiO3, Li2B4O7, Li2MoO4, Li3PO4 ou Li2WO4 pour supprimer la formation d'une impédance interne dans la cellule pendant le stockage et la décharge pouvant se produire avec une dégradation de l'électrolyte.
