  • Cathode and cathode materials for lithium sulfur batteries
    Patent number: 12327834
    Abstract: Provided are electrode active materials with a porous structure and including a metal, that when loaded with sulfur serve as electrochemically superior cathode active materials. The metal structures are optionally used on their own, are coated with another material, or coats another porous structure such as a porous carbon structure that allows for excellent retention of both sulfur and polysulfides, are conductive themselves, and show long term stability and excellent cycle life.
    Type: Grant

    Inventors: Pu Zhang, Michael Wixom, Qingliu Wu
  • Separator for lithium sulfur batteries
    Patent number: 12062752
    Abstract: Provided are materials that may be used in or as a separator in an electrochemical cell such as a lithium sulfur battery. The separator includes a material capable of absorbing and desorbing a polysulfide. The inclusion of the materials in a separator provide for reduced sulfur loss from a cathode during cycling thereby improving cycle life.

  • Carbon and Metal Oxide Composite Cathode for Batteries
    Publication number: 20240128435
    Abstract: A cathode material for a lithium-sulfur battery is disclosed. The cathode material includes an active material comprising a host. The host includes resorcinol-formaldehyde carbon (RFC) and one or both of a metal and metal oxide. Elemental sulfur is coupled to the host. The cathode material may further include a conductive material (e.g., carbon) and a binder material.
