Abstract

A process for producing electric current by the electrochemical oxidation of an active anodic metal dispersed in an alkaline electrolyte. The electrolyte is circulated into contact with a second metal which is more electronegative than the active metal. A displacement reaction precipitates the active metal from its soluble oxidation products. There is obtained as a result a repeated recovery for reuse of the active metal (zinc) with the aid of the more electronegative metal (aluminium) which then supplies the energy for the production of current and is oxidized to form soluble products. The process is exemplified by zinc as the active metal and aluminium and magnesium as the strongly electronegative metals.
