Abstract: The invention relates to an apparatus and a method for producing electrochemical cells, preferably Li-ion cells. The apparatus comprises at least one placing location (13, 15, 17, 19), at least one assembly location (2, 4), a robot system (3) with gripper (150), an automated pipetting machine (5) with cleaning station, a tool for sealing cell stacks and at least one tray with depressions for accommodating components, the number of depressions being in total greater than or equal to two, preferably greater than or equal to four and particularly preferably greater than or equal to six. For assembling the cells, the individual components E1 to E5 are placed in trays on the placing locations and are automatically moved from there by a gripper to the assembly zone and positioned. The zones between the components E2 and E3 and between E3 and E4 are filled with electrolyte. Characteristic features of the apparatus include extremely flexible use with regard to varying different process parameters, elevated throughput and a low reject rate for the produced Li-ion cells.

Abstract: Articles and methods including layers for protection of electrodes in electrochemical cells are provided. As described herein, a layer, such as a protective layer for an electrode, may comprise a plurality of particles (e.g., crystalline inorganic particles, amorphous inorganic particles). In some embodiments, at least a portion of the plurality of particles (e.g., inorganic particles) are fused to one another. For instance, in some embodiments, the layer may be formed by aerosol deposition or another suitable process that involves subjecting the particles to a relatively high velocity such that fusion of particles occurs during deposition. In some embodiments, the layer (e.g., the layer comprising a plurality of particles) is an ion-conducting layer.

Abstract: Articles and methods involving protective membranes for electrochemical cells are generally provided. In some embodiments, a composite protective layer comprising particles and a polymeric binder may be disposed on an electroactive material. The particles may be reactive with lithium, may capable of intercalating lithium, and/or may comprise intercalated lithium. In some embodiments, the electroactive material may be in the form of a first electroactive layer, and a second electroactive layer may be disposed on the composite protective layer. Certain embodiments relate to activating a composite protective layer by intercalating lithium into particles within the layer and/or by reacting the particles with lithium metal.

Abstract: Articles, compositions, and methods involving ionically conductive compounds are provided. The disclosed ionically conductive compounds may be incorporated into an electrochemical cell (e.g., a lithium-sulfur electrochemical cell, a lithium-ion electrochemical cell, an intercalated-cathode based electrochemical cell) as, for example, a protective layer for an electrode, a solid electrolyte layer, and/or any other appropriate component within the electrochemical cell. In certain embodiments, electrode structures and/or methods for making electrode structures including a layer comprising an ionically conductive compound described herein are provided.

Abstract: Sulfur-based electrodes, and associated systems and methods for their fabrication, are generally described. Certain embodiments relate to sulfur-based electrodes with smooth external surfaces. According to some embodiments, relatively large forces can be applied to compositions from which the sulfur-based electrodes are made during the fabrication process.
