Opening claim text (preview).
What is claimed is: 1. An electrochemical cell comprising: a solid-state electrolyte; an anode; and an interfacial layer between the solid-state electrolyte and the anode; wherein the interfacial layer comprises a lithium metal sulfide that comprises LiScS 2 . 2. The electrochemical cell of claim 1 , wherein the solid-state electrolyte comprises Li 3 PS 4 , Li 7 P 3 S 11 , Li 2 SP 2 S 5 , or Li 6 PS 5 Cl. 3. The electrochemical cell of claim 1 , wherein the anode comprises a lithium metal foil, a copper metal foil; or a combination thereof. 4. A solid-state battery comprising: a cathode; and a lithium metal sulfide separating an anode and a solid-state electrolyte; wherein the lithium metal sulfide comprises LiScS 2 . 5. The solid-state battery of claim 4 , wherein the solid-state electrolyte comprises Li 3 PS 4 , Li 7 P 3 S 11 , Li 2 SP 2 S 5 , or Li 6 PS 5 Cl. 6. The solid-state battery of claim 4 , wherein the anode comprises a lithium metal foil, a copper metal foil; or a combination thereof. 7. The solid-state battery of claim 6 , wherein the anode comprises a lithium metal foil and the lithium metal sulfide is formed as a coating on the lithium metal foil. 8. The electrochemical cell of claim 3 , wherein the anode comprises a lithium metal foil and the interfacial layer is a coating on the lithium metal foil. 9. The electrochemical cell of claim 1 , wherein the solid-state electrolyte consists of Li 3 PS 4 , Li 7 P 3 S 11 , Li 2 SP 2 S 5 , or Li 6 PS 5 Cl. 10. A solid-state battery pack comprising a plurality of solid state batteries, each solid state battery comprising: a cathode; and a lithium metal sulfide separating an anode and a solid-state electrolyte; wherein the lithium metal sulfide comprises LiScS 2 . 11. The solid-state battery pack of claim 10 , wherein the solid-state electrolyte comprises Li 3 PS 4 , Li 7 P 3 S 11 , Li 2 SP 2 S 5 , or Li 6 PS 5 Cl. 12. The solid-state battery pack of claim 10 , wherein the anode comprises a lithium metal foil, a copper metal foil; or a combination thereof. 13. The solid-state battery of claim 6 , wherein the anode comprises a lithium metal foil and the lithium metal sulfide is formed as a coating on the lithium metal foil. 14. The solid-state battery pack of claim 10 , wherein the solid-state electrolyte consists of Li 3 PS 4 , Li 7 P 3 S 11 , Li 2 SP 2 S 5 , or Li 6 PS 5 Cl. 15.
