摘要:The present disclosure is directed to processes for the preparation of argyrodite type materials, use of such argyrodite type materials in synthesis of solid-state electrolytes, and inclusion in secondary rechargeable batteries such as lithium ion batteries (LIBs), solid state batteries (SSBs), and/or lithium metal batteries (LMBs). For example, in an aspect the present disclosure provides a process that includes contacting a lithium source with a phosphorus source in a solvent-reagent at a temperature from about 80° C. to about 120° C. to form a precipitate comprising the Li7-xPS6-xYx (where Y is Cl, Br, or I, and 0

标题:Synthesis of Ammonia Using Cycle-Generated Hydrogen Sulfide
发明人：HAMERS ROBERT; BACHMAN BENJAMIN
权利人:WISCONSIN ALUMNI RES FOUND
摘要:Improved methods of synthesizing ammonia from hydrogen sulfide and lithium nitrate are disclosed. Specifically, in a continuous cycle, hydrogen sulfide reactant is regenerated from the elemental sulfur that is extracted from a product of the ammonia synthesis, and the regenerated hydrogen sulfide is fed back into the ammonia synthesis reaction. The cycle that regenerates the hydrogen sulfide uses either a water-containing or a water and carbon-containing feedstock to facilitate the regeneration of the hydrogen sulfide from the elemental sulfur.
