摘要： Chemically treating ionically conductive sulfide glass solid electrolyte separators or separator layers can improve performance. In particular, treatment involving chemically etching a surface or surface region of the sulfide glass separator to blunt, lessen or remove edge defects or surface flaws, and/or to enhance surface smoothness is cost effective, reliable and well suited for high production environments compared to physical methods of removing scratches or smoothing surfaces, such as mechanical grinding and polishing.

摘要： An additive manufacturing ink composition may include a fluid medium. The ink may further include a chalcogenide glass suspended within the fluid medium to form a chalcogenide glass mixture. The ink may also include a surfactant. A method for forming an additive manufacturing ink may include wet milling a chalcogenide glass in a fluid medium and a surfactant to produce a chalcogenide glass mixture. The method may also include, after wet milling the chalcogenide glass, processing the chalcogenide glass mixture to reduce an average particle size of the chalcogenide glass.

摘要： The present invention provides for synthesizing high optical quality multicomponent chalcogenide glasses without refractive index perturbations due to striae, phase separation or crystal formation using a two-zone furnace and multiple fining steps. The top and bottom zones are initially heated to the same temperature, and then a temperature gradient is created between the top zone and the bottom zone. The fining and cooling phase is divided into multiple steps with multiple temperature holds.

摘要： Fiber-reinforced separators/solid electrolytes suitable for use in a cell employing an anode comprising an alkali metal are disclosed. Such fiber-reinforced separators/solid electrolytes may be at least partially amorphous and prepared by compacting, at elevated temperatures, powders of an ion-conducting composition appropriate to the anode alkali metal. The separators/solid electrolytes may employ discrete high aspect ratio fibers and fiber mats or plate-like mineral particles to reinforce the separator solid electrolyte. The reinforcing fibers may be inorganic, such as silica-based glass, or organic, such as a thermoplastic. In the case of thermoplastic fiber-reinforced separators/solid electrolytes, any of a wide range of thermoplastic compositions may be selected provided the glass transition temperature of the polymer reinforcement composition is selected to be higher than the glass transition temperature of the amorphous portion of the separator/solid electrolyte.

摘要： Thin amorphous or partially crystalline lithium-containing and conducting sulfide or oxysulfide glass electrode/separator members are prepared from a layer of molten glass or of glass powder. The resulting glass films are formed to lie face-to face against a lithium metal anode or a sodium metal anode and a cathode and to provide for good transport of lithium ions between the electrodes during repeated cycling of the cell and to prevent shorting of the cell by dendrites growing from the lithium metal or sodium metal anode.
