ABSTRACT:
The improved self-supporting electrode of the present invention comprises a uniform mixture of cuprous chloride, preferably in major proportion and silver chloride, preferably in minor proportion. The electrode may also include a minor proportion of copper metal uniformly dispersed therein. The electrode is primarily used as a cathode, particularly in cells employing sea water as the electrolyte. The cathode preferably is formed by mixing the ingredients together and melting at least the cuprous chloride and silver chloride of the mixture and then casting the mixture and solidifying it so as to cause it to adhere to a current collector such as expanded copper metal. The current collector preferably is at or near the surface of the electrode and helps to support the electrode. The electrode is less expensive than one fabricated solely of silver chloride and yet is more resistant to degradation by humidity and has better electrical properties than conventional cuprous chloride electrodes.
