Title
(EN) NICKEL POSITIVE ELECTRODE HAVING HIGH-TEMPERATURE CAPACITY
(FR) ELECTRODE POSITIVE DE NICKEL A CAPACITE A HAUTE TEMPERATURE
Abstract
(EN)
A positive electrode active material mixture comprising: a nickel hydroxide material, and an additive material comprising at least one element selected from the group consisting of calcium cobalt oxide, calcium titanium oxide, calcium molybdenum oxide, lithium cobalt oxide, and mixtures thereof. A nickel positive electrode comprising this active material mixture. A nickel-based, alkaline electrochemical cell comprising this positive electrode.
(FR)
L'invention concerne un mélange de matière active d'électrode positive comprenant: une matière d'hydroxyde de nickel et une matière d'additif comprenant au moins un élément sélectionné dans le groupe formé par de l'oxyde de cobalt de calcium, de l'oxyde de titane de calcium, de l'oxyde de molybdène de calcium, de l'oxyde de cobalt de lithium et leurs mélanges. L'invention concerne également une électrode positive de nickel comprenant ce mélange de matière active. L'invention concerne enfin une cellule électrochimique alcaline à base de nickel comprenant cette électrode positive.
