Title
(EN) DRY BATTERY HAVING A CATHODE WITH ADDITIVES
(FR) PILE SECHE A ADDITIFS DE CATHODE
Abstract
(EN)
The battery is of the primary alkaline type and comprises a zinc anode, an anodic gel and a cathode. The cathode comprises a depolarizing mixture based on manganese dioxide containing a mica powder whose grains have a surface at least partially coated with titanium dioxide.
(FR)
La présente invention concerne une pile électrique de type primaire alcalin comprenant une anode de zinc, un gel d'anode et une cathode. Cette cathode inclut un mélange dépolarisant à base de dioxyde de manganèse et contenant une poudre de mica dont la surface des grains est enduite, au moins partiellement, de dioxyde de titane.
