  • 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.
    Type: Grant
    Filed: December 4, 2019
    Date of Patent: March 8, 2022
    Assignee: Apple Inc.
    Inventors: Mona Shirpour, Tetsuya Ishikawa, Sally S. Lou, Juchuan Li, Shawn William Snyder
  • CATHODE FOR SOLID-STATE LITHIUM BATTERY
    Publication number: 20210359339
    Abstract: The disclosure provides a solid-state battery including a cathode comprising a lithium-based conducting material having a porosity less than or equal to 6% and a surface roughness of equal to or less than 300 nm. The solid-state battery may also include an anode and a solid electrolyte between the cathode and the anode.

  • Liquid metal electrodes for rechargeable batteries
    Patent number: 8841014
    Abstract: An electrode for a lithium ion battery includes a liquid metal having a melting point that is below the operating temperature of the battery, which transforms from a liquid to a solid during lithiation, and wherein the liquid metal transforms from a solid to a liquid during delithiation.
