Abstract
Abstract An aluminum-chlorine, thermally activated, electrochemical cell composed of an aluminum anode, an inert metal cathode and a two-layered pelletized electrolyte sandwiched therebetween and composed of a mixture of aluminum chloride with one or more salts of sodium chloride, lithium chloride, potassium chloride and tetra-substituted ammonium chloride.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
108 words
An aluminum-chloride electrochemical cell comprising: a. an anode composed of an aluminum metal sheet; b. a cathode composed of chlorine as an electroactive material in contact with a tungsten metal sheet which serves as a cathodic current collector; and c. a two-layered, pelletized, electrolyte wafer sandwiched between said anode and said cathode, said wafer having both layers composed of a sodium chloride saturated equimolar mixture of aluminum chloride and sodium chloride immobilized in silicon dioxide and an amount of powdered graphite only in that layer adjacent to said cathode to act as a cathodic site, and an electronic conductor leading from the wafer interior to the current collector.
