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.

Voltage and reduced polarization within mercury free zinc air cells

The present disclosure relates to alkaline electrochemical cells, such as metal-air cells, which comprise a gelled anode which may or may not include mercury, comprising an ionically conductive clay additive. The ionically conductive clay additive is modified to include halogen atoms to increase the negative charge density of the additive and improve its performance in the electrochemical cell.
