Abstract
The present disclosure is directed to a zinc air cell with improved voltage and reduced polarization. The combination of an anode corrosion inhibitor with a surfactant system yields enhanced cell voltage and capacity for the cell that are above the individual contributions of the corrosion inhibitor and the surfactant system.
