  • Cathode for solid-state electrochemical cell having elemental dopant in grain boundaries
    Patent number: 11811063
    Abstract: A solid-state cathode for a solid-state electrochemical cell includes an electrochemically active cathode material and one or more elemental dopant residing in grain boundaries of the electrochemically active cathode material. The grain boundaries contain at least 0.2 wt % of the one or more elemental dopant and the one or more elemental dopant is less than 10 wt % of the solid-state cathode. The solid-state cathode does not have liquid, gel and polymer materials.
    Type: Grant
    Filed: December 1, 2020
    Date of Patent: November 7, 2023
    Assignee: APPLE INC.
    Inventors: Shawn William Snyder, Terry Tiegs, Jeffrey J. Kelly, Damon E. Lytle, Bernd Jurgen Neudecker, Jianer Bao, Mona Shirpour
  • Cathode active material with silicon carbide additive
    Patent number: 11271210
    Abstract: A lithium battery cathode material comprises lithium transition metal-based material selected from lithium transition metal oxides and lithium transition metal phosphates, and crystalline silicon carbide residing at grain boundaries of the lithium transition metal-based material, forming conductive pathways along the grain boundaries, the crystalline silicon carbide being less than 10 wt. % of the cathode material.
