Abstract

L'invention concerne des séparateurs auxiliaires négatifs pour accumulateurs alcalins. Elle se rapporte à un séparateur auxiliaire négatif qui contient 50 à 95 % en poids d'une matière à base de titanate, par exemple de titanate de potassium, ainsi qu'un matière minérale fibreuse formant un support, telle que l'amiante, et éventuellement un agent épaississant Le séparateur auxiliaire négatif est placé entre l'électrode négative et le séparateur principal d'un accumulateur alcalin. Application à la réalisation d'accumulateurs électriques alcalins à longue durée d'utilisation.
