Abstract: A process for producing a low-cost water-reactive sulfide material includes reacting a substantially anhydrous first alkali metal salt, a substantially anhydrous first sulfide compound, and a substantially anhydrous first alkali metal hydrosulfide compound in a substantially anhydrous polar solvent, providing differential solubility for a substantially high solubility second sulfide and a substantially low solubility second alkali metal salt, and forming a mixture of the high solubility second sulfide, a second alkali metal hydrosulfide, and the low solubility second alkali metal salt; removing the low solubility second alkali metal salt to isolate the supernatant including the second sulfide, and separating the polar solvent from the second sulfide and the second alkali metal hydrosulfide followed by heating to produce the second sulfide. The present disclosure provides a scalable process for production of a high purity alkali metal sulfide that is essentially free of undesired contaminants.

Abstract: A process for producing a low-cost water-reactive metal sulfide material includes dissolving a substantially anhydrous alkali metal salt and a substantially anhydrous sulfide compound in a substantially anhydrous polar solvent, providing differential solubility for a substantially high solubility alkali metal sulfide and a substantially low solubility by-product, and forming a mixture of the high solubility alkali metal sulfide and the low solubility by-product; separating the low solubility by-product from the mixture to isolate the supernatant including the alkali metal sulfide, and separating the polar solvent from the alkali metal sulfide to produce the alkali metal sulfide. The present invention provides a scalable process for production of a high purity alkali metal sulfide that is essentially free of undesired by-products.

Abstract: A resilient battery cell is provided that includes an electrode and an electrolyte hermetically sealed within a pouch. The pouch includes layers of heat-resistant and resilient materials coupled together by a thermoplastic seal. A conductive tab electrically coupled to the electrode and for electrically coupling of the battery cell to other cells and/or a battery terminal extends through and is hermetically sealed by the sealant. The battery cell may further include supplemental layers external the pouch for providing structural integrity, a vapor barrier, improved fire safety, and other benefits.

Abstract: An encapsulated electrode for an electrochemical cell and a method for producing an encapsulated electrode. The encapsulated electrode structure has a first solid-state electrolyte composite (SSE) that has a top surface, a bottom surface, and a peripheral surface. Another layer of the encapsulated electrode structure is the electrode that has a top surface, a bottom surface, and a peripheral surface. Yet another layer of the encapsulated electrode structure is a second SSE that has a top surface, a bottom surface, and a peripheral surface. The first SSE is arranged so as to be attached to the electrode, wherein the bottom surface of the first SSE is attached to the top surface of the electrode. The bottom surface of the electrode is attached to the top surface of the second SSE. Pressure is applied to this stack so that the SSEs deform and encapsulate the electrode.
