Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
53 words
A non-aqueous cell comprising an anode, a cathode collector and a cathode-electrolyte comprising an ionizing solute dissolved in a cathodic solvent of an halogenocarbonylchalcogenyl halide as represented by the formula ##STR8## where X 1 and X 2 are halogens and where Y is a chalcogen having an atomic number of 16 or more.
Claim 2
Dependent Claim
53 words
A non-aqueous cell comprising an anode, a cathode collector and a cathode-electrolyte comprising an ionizing solute dissolved in a cathodic solvent of an halogenocarbonylchalcogenyl halide as represented by the formula ##STR8## where X 1 and X 2 are halogens and where Y is a chalcogen having an atomic number of 16 or more.
Claim 3
Dependent Claim
21 words
The non-aqueous cell of claim 1 wherein the halogen is selected from the group consisting of chlorine, fluorine, bromine and iodine.
Claim 4
Dependent Claim
22 words
The non-aqueous cell of claim 1 or 2 wherein the chalcogen is selected from the group consisting of sulfur, selenium and tellurium.
Claim 5
Dependent Claim
12 words
The non-aqueous cell of claim 1 wherein the halogenocarbonylchalcogenyl halide is ClC(O)SCl.
