ABSTRACT:
Negative sintered foil electrodes for gas-tight Ni/Cd storage batteries can be provided with a specific discharge reserve by subjecting them to a partial chemical reduction before they are installed. This is performed upon the moving, impregnated sinter tape by immersing it in or spraying it with a strongly reducing agent dissolved in water or any other solvent, preferably alkali boranate. In a subsequent drying step, the Cd so formed is permanently fixed and protected through intentional surface oxidation.
