  • Electrodes with silicon oxide active materials for lithium ion cells achieving high capacity, high energy density and long cycle life performance
    Patent number: 11742474
    Abstract: Improved negative electrodes can comprise a silicon based active material blended with graphite to provide more stable cycling at high energy densities. In some embodiments, the negative electrodes comprise a blend of polyimide binder mixed with a more elastic polymer binder with a nanoscale carbon conductive additive. The silicon-based blended graphite negative electrodes can be matched with positive electrodes comprising nickel rich lithium nickel manganese cobalt oxides to form high energy density cells with good cycling properties.
    Type: Grant
    Filed: July 8, 2021
    Date of Patent: August 29, 2023
    Assignee: Zenlabs Energy, Inc.
