Abstract: Aspects involve systems and methods for producing an electrode laminate for a battery that includes a stack of a center electrode layer, a solid-state electrolyte (SSE) layer, and carrier film layer (such as an aluminum foil layer), which is removed prior to use in a cell. To laminate the lithium foil layer to the SSE layers, the stack may be fed through a calender press device comprising a first roller and a second roller. The rollers exert a compressive force on the stack to laminate the layers together while also reducing the porosity of the materials within the stack (densifying), enhancing material contact, causing some layers to adhere or otherwise laminate, and/or also causing some layers to partially separate. The pressure applied to the stack by the calender press may correlate to a spacing between the first roller and the second roller, which may be adjustable by a controller.

Abstract: A peeling device for manufacturing of an electrode stack includes an upper wedge and a lower wedge between which the electrode stack is fed after a calendering process. A respective lifting roller may be located at the output ends of each of the wedges, which through coordinated action peels the aluminum layers away from the corresponding layer of the electrode stack. The peeling force, exerted by rollers capturing upper and lower aluminum foil sheets of the stack, may be controlled and relatively uniform, thereby enhancing the ability to peel the foil from the stack while not damaging the relatively delicate remaining layers. The aluminum foil is directed away from the stack along an outer planar surface of the respective wedge where the foil can then be wound around the respective rollers.

Abstract: A process for producing a low-cost water-reactive sulfide material includes reacting a substantially anhydrous first alkali metal salt, a substantially anhydrous first sulfide compound, and a substantially anhydrous first alkali metal hydrosulfide compound in a substantially anhydrous polar solvent, providing differential solubility for a substantially high solubility second sulfide and a substantially low solubility second alkali metal salt, and forming a mixture of the high solubility second sulfide, a second alkali metal hydrosulfide, and the low solubility second alkali metal salt; removing the low solubility second alkali metal salt to isolate the supernatant including the second sulfide, and separating the polar solvent from the second sulfide and the second alkali metal hydrosulfide followed by heating to produce the second sulfide. The present disclosure provides a scalable process for production of a high purity alkali metal sulfide that is essentially free of undesired contaminants.
