  • 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.

  • Solid solution cathode for solid-state battery
    Patent number: 10784506
    Abstract: A cathode for a solid-state battery comprises a composite cathode active material formed of a layered lithium cobalt oxide (LCO) in a solid solution matrix of lithium oxide (Li2O) and a cobalt oxide phase. For example, the composite cathode active material can be layered LCO in a solid solution matrix of one of Li2O—LixCo1-xO—Co3O4, Li2O—LixCo1-xO and Li2O—Co3O4, with 0?x?0.5. The LCO is at least 80 wt. % of the composite cathode active material. The cathode is a sintered solid-state cathode wafer that is free-standing, upon which solid-state battery cells are fabricated.
