A cadmium patch laminar electrode, comprising a dispersion of particulate cadmium in a binder matrix on a conductive plastic substrate is prepared by contacting a zinc patch electrode comprising a dispersion of particulate zinc in a binder matrix on a conductive plastic substrate with an aqueous solution of a cadmium salt. The cadmium patch electrode can be used in a primary electrochemical cell such as that employing a manganese dioxide cathode and a cadmium chloride electrolyte.
