ABSTRACT:
An anode coating for anhydrous electrochemical generating cells is disclosed wherein the anode active material is immersed in an electrolyte solution and coated with the insoluble reaction product of the anode metal with an inhibiting reactant such as CO.sub.2, SO.sub.2, O.sub.2, NH.sub.3, and N.sub.2 saturated with respect to water vapor. This coating is insoluble in the cell under open circuit conditions and is stable with regard to said electrolyte but is removable in said electrolyte, when the cell is discharged with a negligible over voltage. The coated anodes and the method for making same are specifically described. Cells with anodes treated according to this invention have been stored at 55.degree. C., for extended periods with negligible self discharge.
