Abstract
Disclosed is a method of electrolyzing an alkali metal chloride brine where the cathode is an intercalation compound of graphite and a transition metal. Also disclosed is a solid polymer electrolyte having as its cathode an intercalation compound of graphite and a transition metal, and an electrolytic cell having as its cathode an intercalation compound of graphite and a transition metal.
Claims8
In a method of electrolyzing an alkali metal chloride brine in an electrolytic cell having an anolyte compartment with an anode therein, a catholyte compartment with a cathode therein, and an ion permeable separator therebetween, which method comprises feeding the brine to the anolyte compartment, passing an electrical current from the anode to the cathode, and recovering chlorine from the anolyte compartment and alkali metal hydroxide solution from the catholyte compartment, the improvement wherein the cathode comprises an intercalation compound comprising graphite and transition metal component.
