This invention relates to a process for manufacturing a primary zinc-alkaline battery, which comprises the step of preparing a gelled alkaline anode mix containing an aluminiferous zinc alloy powder as an active material, characterized in that a powered calcium compound is used as an ingredient of the anode mix in a sufficient amount to lower the tendency the battery shows to develop a short-circuit when the calcium compound is absent in its anode mix, or the separator paper contains a calcium compound.
L'invention concerne un procédé pour fabriquer une batterie alcaline au zinc primaire. Ce procédé comprend les étapes consistant à préparer un mélange anodique alcalin gélifié contenant une poudre d'alliage de zinc aluminifère comme matériau actif. Ce procédé se caractérise en ce qu'on utilise un composé de calcium pulvérulent comme ingrédient du mélange anodique selon une quantité suffisante pour réduire la tendance de la batterie à générer un court-circuit en l'absence de composé de calcium dans son mélange anodique, ou lorsque le papier séparateur contient un composé de calcium.
