Abstract : The patent describes a cadmium electrode prepared by positioning a porous nickel plaque between two cadmium sheets immersed in an aqueous solution of cadmium nitrate having a pH of 3 to 5 and maintained at a temperature of 95 to 110C. After connecting the nickel plaque to the negative pole and the cadmium sheets to the positive pole of a power source, direct current is passed through the solution at 1.2 to 1.6 amperes per square inch of plaque for from 8 to 20 minutes, thereby causing deposition of cadmium metal and cadmium hydroxide inside the pores of the plaque. A cadmium electrode so prepared is especially useful as the negative electrode in nickel-cadmium batteries.
