    Abstract: Molten lithium-sulfur and lithium-selenium electrochemical cells are disclosed. A solid electrolyte separates a molten lithium metal or molten lithium metal alloy from a molten sulfur or molten selenium. The molten lithium-sulfur and lithium-selenium cells have low over potential, no side reaction, and no dendrite growth. These cells have high Coulombic efficiency and energy efficiency and thus provide new chemistries to construct high-energy, high-power, long-lifetime, low-cost and safe energy storage systems.

  • 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.
