The use of fibril materials, such as fibril cellulose materials and other similar materials, in electrochemical cells and components thereof is generally described.


Layer composites, electrodes comprising or consisting of said layer composites, electrochemical cells comprising said electrodes, and methods for forming said layer composites are generally described.


Patent
Sion Power | Date: 2016-11-28

Articles and methods for forming protected electrodes for use in electrochemical cells, including those for use in rechargeable lithium batteries, are provided. In some embodiments, the articles and methods involve an electrode that does not include an electroactive layer, but includes a current collector and a protective structure positioned directly adjacent the current collector, or separated from the current collector by one or more thin layers. Lithium ions may be transported across the protective structure to form an electroactive layer between the current collector and the protective structure. In some embodiments, an anisotropic force may be applied to the electrode to facilitate formation of the electroactive layer.

Articles and methods including additives in electrochemical cells, are generally provided. As described herein, such electrochemical cells may comprise an anode, a cathode, an electrolyte, and optionally a separator. In some embodiments, at least one of the anode, the cathode, the electrolyte, and/or the optional separator may comprise an additive and/or additive precursor. For instance, in some cases, the electrochemical cell comprises an electrolyte and an additive and/or additive precursor that is soluble with and/or is present in the electrolyte. In some embodiments, the additive precursor comprises a disulfide bond. In certain embodiments, the additive is a carbon disulfide salt. In some cases, the electrolyte may comprise a nitrate.

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.


An electrochemical cell including at least one nitrogen-containing compound is disclosed. The at least one nitrogen-containing compound may form part of or be included in: an anode structure, a cathode structure, an electrolyte and/or a separator of the electrochemical cell. Also disclosed is a battery including the electrochemical cell.

Patent
Sion Power and Basf | Date: 2016-09-27

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.
