First claim
Opening claim text (preview).
We claim: 1 . A lithium sulfur cell, comprising: a cathode comprising Li 3 PS 4+n (0<n<9); an electrolyte; and an anode comprising lithium. 2 . The lithium sulfur cell of claim 1 , wherein the cathode comprises Li 3 PS5. 3 . The lithium sulfur cell of claim 1 , wherein the cathode comprises Li 3 PS 6 . 4 . The lithium sulfur cell of claim 1 , wherein the cathode comprises Li 3 PS 7 . 5 . The lithium sulfur cell of claim 1 , wherein the cathode comprises Li 3 PS 8 . 6 . The lithium sulfur cell of claim 1 , wherein the cathode comprises Li 3 PS 9 . 7 . The lithium sulfur cell of claim 1 , wherein the cathode comprises Li 3 PS 10 . 8 . The lithium sulfur cell of claim 1 , wherein the cathode comprises Li 3 PS 11 . 9 . The lithium sulfur cell of claim 1 , wherein the cathode comprises Li 3 PS 12 . 10 . The lithium sulfur cell of claim 1 , wherein the electrolyte comprises at least one selected from the group consisting of lithium thiophosphate, lithium lanthanum zirconium oxide, lithium lanthanum titanium oxide, lithium boron hydride, and lithium iodide, and combinations thereof. 11 . The lithium sulfur cell of claim 1 wherein the anode comprises at least one selected from the group consisting of lithium, silicon, silicon monoxide, tin, and tin oxide. 12 . A cathode for a lithium sulfur cell, comprising Li 3 PS 4+n (0<n<9). 13 . The cathode of claim 12 , comprising Li 3 PS 5 . 14 . The cathode of claim 12 , comprising Li 3 PS 6 . 15 . The cathode of claim 12 , comprising Li 3 PS 7 . 16 . The cathode of claim 12 , comprising Li 3 PS 8 . 17 . The cathode of claim 12 , comprising Li 3 PS 9 . 18 . The cathode of claim 12 , comprising Li 3 PS 10 . 19 . The cathode of claim 12 , comprising Li 3 PS 11 . 20 . The cathode of claim 12 , comprising Li 3 PS 12 . 21 . A method of making a cathode for a battery, comprising the steps of: reacting sulfur with Li 3 PS 4 in a liquid solvent to provide a composition comprising Li 3 PS 4+n (0<n<9), creating a slurry with the compound, a binder and carbon; and, forming a cathode with the slurry. 22 . The method of claim 21 , wherein the solvent is at least one selected from the group consisting of tetrahydrofuran, acetonitrile, dimethoxylethane, glyme solvents and ethers.
