权利人:RIVIAN IP HOLDINGS LLC
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

发明人：WANG HUI; DRUFFEL THAD; BUCHBERGER DOMINIKA AGNIESZKA
权利人:BUCHBERGER DOMINIKA AGNIESZKA; UNIV LOUISVILLE RES FOUND INC; UNIV WARSZAWSKI; Uniwersy tet Warszawski
摘要:Methods for wet chemical synthesis of lithium argyrodites are provided, which in some embodiments include includes dissolving a stoichiometric mixture of precursors in a small quantity of solvent in an argon atmosphere, drying the mixture under vacuum or an inert gas atmosphere to evaporate the solvent, and then annealing to obtain a final lithium argyrodite product. Further embodiments comprise synthesizing the precursors, and excess halide doping to achieve higher ionic conductivity.
