Process for preparing zinc powder for alkaline batteries
Patent
·
OSTI ID:6053839
A zinc powder having a low gas evolution in an alkaline electrolyte for use in an alkaline battery are obtained by alloying the zinc with at least one metal selected from the group consisting of lead, cadmium, thallium and indium and at least one further metal selected from the group consisting of lead, cadmium, thallium, indium gold, silver, tin and gallium. Thereby it is possible to avoid the use of mercury as an alloying element but nevertheless to obtain a zinc powder which meet all of the requirements for use in alkaline batteries.
