Abstract: Provided herein are methods of preparing Li2S. The methods generally include combining an alkaline metal sulfide, a lithium salt, an alcohol, and a hydrocarbon to form a mixture. A reaction forms the Li2S. A dense solvent is then added to the mixture and the Li2S is isolated from the mixture.

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: Provided herein are methods for making Li2S. The method includes combining metal polysulfides, metal sulfides, metal salts, elemental sulfur in a solvent to form a mixture and isolating Li2S from the mixture. Provided herein are also methods for purifying the isolated Li2S forming a high-purity Li2S. Further provided herein are methods for making solid-state electrolytes.
