Electrochemical cell with a cadmium patch electrode
First Claim
1. A primary electrochemical cell comprising an anode comprising cadmium, a cathode comprising manganese dioxide and an electrolyte consisting essentially of aqueous cadmium chloride wherein said anode is a cadmium dry patch anode and is prepared by contacting a zinc patch electrode which comprises a dispersion of particulate zinc in a binder matrix deposited on a conductive plastic substrate with an aqueous solution of cadmium salt for a time sufficient for the zinc and cadmium to undergo a mutual exchange reaction.

Abstract
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.
