Electrolytic process for forming cadmium electrodes

Abstract

Abstract The invention relates to a process for the preparation of sponge cadmium electrode material which comprises the steps of compressing the mixture of cadmium oxide and a finely divided inert electronic conductor at a pressure between about 1 psi and 100 psi, and subsequently electrolytically reducing the cadmium oxide to metallic cadmium in an alkaline electrolyte. Preferably the cadmium oxide is used in the form of a powder having a particle size between about 50 microns and 150 microns while the electrolytic conductor is preferably finely divided nickel powder or a metal in filamentary form such as steel wool, nickel wool, or electrolytic copper wool and is furthermore preferably used in a proportion amounting to between 5 and 45 percent by weight of the total mixture. Particularly good results are obtained when the compressing pressure is between about 1 and 4 psi.
