Abstract: Aspects of the present disclosure involve a plasma system for practicing various methods of synthesizing solid-state electrolyte materials and precursors for solid-state electrolyte materials.

Abstract: A process for preparing a solid electrolyte that includes mixing a lithium source with a sulfur source and a compound containing phosphorous and sulfur to form a composite, then heating the composite to the melting point of the compound containing phosphorous and sulfur to form the solid electrolyte material. A solid electrolyte material prepared by the process, wherein the solid electrolyte material is of formula I, which is Li(7?y?z)PS(6?y?z)X(y)W(z) wherein X and W are individually selected from F, Cl, Br, and I; where y and z each individually range from 0 to 2; and where y+z ranges from 0 to 2.

Abstract: A method for synthesizing solid-state electrolytes and for synthesizing precursors for solid-state electrolytes by plasma-processing.

Abstract: Ultrafine metal oxide and mixed metal oxide ceramic particles are prepared by flame spray pyrolysis of a ceramic precursor solution containing one or more gycolato polymetallooxanes dissolved in a volatile organic solvent. Recycle of the nanosized particles disposed in additional ceramic precursor solution leads to larger particles. The metal oxide and mixed metal oxide particles may be converted to the respective nitrides by high temperature ammonolysis. The process produces high quality ceramic particles from inexpensive and relatively non-toxic reagents in high space-time yield.

Abstract: A process for the preparation of polymetallooxanes employing inexpensive metal sources such as sand, alumina, and rutile involves dissolving one or more group IIIa, IVa, IVb metaloxy compounds such as metal oxides, metal hydroxides, or hydrates thereof with a di- or polyhydroxyl functional compound in the presence of an amine or alkanolamine. The polymetallooxane products are anionic, neutral, or mixed neutral/anionic moieties, which, when anionic, contain a metallic counterion (cation) or an ammonium or phosphonium ion. Mixed polymetallooxanes, as well as homo polymetallooxanes which may be prepared by the subject process, are suitable for use in preparing coatings, fibers, powders, ceramics, and glasses while being easily processable and economic to manufacture.
