Abstract: Articles, compositions, and methods involving ionically conductive compounds are provided. In some embodiments, the ionically conductive compounds are useful for electrochemical cells. 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: 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 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 aspects, at least a portion of the plurality of particles (e.g., inorganic particles) are fused to one another. For instance, in some aspects, 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 cases, the protective layer may be porous.
