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 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.

Abstract: Systems and methods of using a laser cutting device to cut an electrode laminate for a battery. The laser cutter may super heat and volatilize the various components of the layers of the electrode stack. The laser cutter may be programmed or otherwise controlled to direct its laser to cut the electrode stack into any shape. Further, as the laser cutter super heats the materials within the layer(s), the material may volatilize or ablate and be removed from the environment with simple vacuum systems, thereby reducing or eliminating metal shards and other contaminants that may be generated through conventional cutting procedures that damage or short-circuit the electrode. This “cauterization” process may also generate a unique pattern or composition of oxides and hydroxides of the electrode that is identifiable through a chemical mapping process to uniquely identify, or “fingerprint”, the electrode based on the chemical make-up of the cut electrode stack.

Abstract: Provided herein are methods of preparing Li2S. The methods generally include combining an alkaline metal sulfide, a lithium salt, an alcohol, and a hydrocarbon to form a mixture. A reaction forms the Li2S. A dense solvent is then added to the mixture and the Li2S is isolated from the mixture.

Abstract: Provided herein is a negative electrode or anode for an electrochemical cell, the anode comprising nanoscale silicon. The nanoscale silicon facilitates the formation of vertical cracks in the anode layer when the anode is cycled in an electrochemical cell, which improves cell performance as compared to a silicon anode that forms random or horizontal cracks when the anode is cycled.

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