    Abstract: Aspects involve systems and methods for producing an electrode laminate for a battery that includes a tension device to maintain tension on an electrode stack as the stack is cut into a shape. The tension device may include a first roller and a second. The upper roller may rotate in a counterclockwise direction as the lower roller rotates in a clockwise direction to pull or otherwise draw a skeleton of a cut stack through the tension device. A collection of spaced flexible and resilient flaps may be connected to the upper roller and may rotate with the upper roller. A contacting edge of each of the flaps may contact the skeleton of the stack and gently pull the skeleton through the tension device providing a relatively continuous pull on the stack as it proceeds through a cutting station.

    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.

    Abstract: Aspects of the present disclosure relate to prelithiating an electrode of an electrochemical cell to counteract lithium loss as an electrochemical cell is formed and cycled. One implementation may include a method comprising a) providing an electrode composite with lithium-ion conductivity and diffusivity, the electrode composite comprising a silicon-containing material, a carbon-based conductive additive, a solid electrolyte, and a binder; b) disposing a continuous thin layer of lithium proximate to the electrode composite; and c) pressure laminating the continuous thin layer of lithium to the electrode composite. Through the process, lithium is transferred to the solid-state electrode composite by contacting the lithium metal film with the electrode composite without the use of a liquid medium traditionally used to aid in the movement of lithium ions.

    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.
