  • COATING FOR ELECTRODE ACTIVE MATERIALS, ELECTRODES, AND ELECTROCHEMICAL CELLS THEREOF
    Publication number: 20260121067
    Abstract: Coated cathode active materials include a cathode active material that is coated by a hydroxide-containing material, such as a metal hydroxide. The coated cathode active materials may be incorporated into electrochemical cells, including solid-state batteries. Electrochemical cells including the coated cathode active materials have improved capacity retention as compared to electrochemical cells including un-coated cathode active materials.
    Type: Application
    Filed: October 31, 2025
    Publication date: April 30, 2026
    Inventors: Megan M. WEBSTER, Alexandra BOTHWELL, Ayana S. WEST, Jason E. ROBERTS
  • COMPOSITE COATING FOR CATHODE ACTIVE MATERIALS, AND SOLID-STATE CELL MADE THEREOF
    Publication number: 20260011744
    Abstract: Coated cathode active materials include a cathode active material particle and a composite coating layer disposed on a surface of the cathode active material particle. The composite coating layer includes a carbonate material and a hydroxide material, and the carbonate material is disposed on a surface of the hydroxide material. The coated cathode active materials are incorporated into solid-state electrochemical cells.

  • TECHNIQUES FOR COATING CATHODE MATERIAL AND CREATING ADDITIVES FOR CATHODE COMPOSITES, AND SOLID-STATE BATTERIES INCORPORATING THE SAME
    Publication number: 20250192157
    Abstract: Cathode composites for use in solid-state electrochemical cells include a cathode active material that is coated with a metal hydroxide. Additionally, cathode active composites for use in solid- state electrochemical cells include a cathode active material and a metal hydroxide that is distributed throughout the cathode composite. Electrochemical cells that include the cathode composites exhibit improved performance.
