  • Publication number: 20220020979
    Abstract: Provided are examples of electrochemically active electrode materials, electrodes using such materials, and methods of manufacturing such electrodes. Electrochemically active electrode materials may include a high surface area template containing a metal silicide and a layer of high capacity active material deposited over the template. The template may serve as a mechanical support for the active material and/or an electrical conductor between the active material and, for example, a substrate. Due to the high surface area of the template, even a thin layer of the active material can provide sufficient active material loading and corresponding battery capacity. As such, a thickness of the layer may be maintained below the fracture threshold of the active material used and preserve its structural integrity during battery cycling.

  • Patent number: 11121396
    Abstract: An electrode includes one or more intermediate layers positioned between a substrate and an electrochemically active material. Intermediate layers may be made from chromium, titanium, tantalum, tungsten, nickel, molybdenum, lithium, as well as other materials and their combinations. In certain embodiments, an active material includes one or more high capacity active materials, such as silicon, tin, and germanium. These materials tend to swell during cycling and may loose mechanical and/or electrical connection to the substrate. A flexible intermediate layer may compensate for swelling and provide a robust adhesion interface. Methods of fabricating electrodes involve forming metal silicide nanostructures.

  • Patent number: 11056679
    Abstract: Provided are methods of introducing additional lithium ions into lithium-ion electrochemical cells as well as positive electrodes, comprising these additional lithium ions. A method may involve introducing a temporary lithium additive into a positive electrode, such as mixing the additive into slurry used for coating the electrode. The positive electrode also comprises a positive active material, different from the temporary lithium additive and used as a source of primary lithium ions. The positive active material is operable to release and also later to receive lithium ions during cycling. The temporary lithium additive is operable to release additional lithium ions during its decomposition, but not to receive any lithium ions thereafter. The amount of these additional lithium ions may be selected based on expected lithium ion losses in the cell. The temporary lithium additive may decompose when applying a voltage between the electrodes, e.g., during initial cycling.

  • Patent number: 11056704
    Abstract: Provided are hybrid active material structures for use in electrodes of electrochemical cells and methods of forming these structures. A hybrid active material structure comprises at least one first substructure and at least one second substructures, each comprising a different layered active material and interfacing each other. Combining multiple layered active materials into the same structure and arranging these materials in specific ways allow achieving synergetic effects of their desirable characteristics. For example, a layered active material, which forms a stable solid electrolyte interface (SEI) layer, may be form an outer shell of a hybrid active material structure and interface with electrolyte. This shell may surround another layered active material, which has a higher capacity but would otherwise forma a less stable SEI layer. Furthermore, multiple layered active materials may be arranged into a stack, in which one of these materials may operate as an ionic and/or electronic conductor.
