Abstract

Abstract Translated from German Zinkpulver für alkalische Batterien mit geringer Gasentwicklung im alkalischen Elektrolyten werden durch Legieren des Zinks erhalten, indem man das Zink mit mindestens einem der Metalle der Reihe Blei, Cadmium, Thallium und Indium sowie mindestens einem weiteren Metall der Reihe Blei, Cadmium, Thallium, Indium, Gold, Silber, Zinn und Gallium legiert. Es ist so möglich, Quecksilber als Legierungsmetall zu vermeiden und dennoch zu Zinkpulvern zu gelangen, die alle Anforderungen für alkalische Batterien erfüllen. Zinc powder for alkaline batteries with low gas evolution in the alkaline electrolyte are obtained by alloying the zinc by mixing the zinc with at least one of the metals from the series lead, cadmium, thallium and indium and at least one further metal from the series lead, cadmium, thallium, indium, Gold, silver, tin and gallium alloyed. In this way it is possible to avoid mercury as an alloy metal and still obtain zinc powders that meet all the requirements for alkaline batteries.
