  • Method of manufacturing an electrochemical cell
    Patent number: 10797353
    Abstract: A method of manufacturing an electrochemical cell may comprise exposing a surface of a metal substrate to a chalcogen in gas phase such that a metal chalcogenide layer forms on the surface of the metal substrate. A lithium metal foil may be laminated onto the metal chalcogenide layer on the surface of the metal substrate such that a surface of the lithium metal foil physically and chemically bonds to the metal chalcogenide layer on the surface of the metal substrate.
    Type: Grant
    Filed: January 4, 2018
    Date of Patent: October 6, 2020
    Assignee: GM Global Technology Operations LLC
    Inventors: Keegan Adair, Fang Dai, Mei Cai
  • Electrochemical cell and method of manufacturing
    Patent number: 10593931
    Abstract: An electrochemical cell comprising a lithium metal negative electrode layer physically and chemically bonded to a surface of a negative electrode current collector via an intermediate metal chalcogenide layer. The intermediate metal chalcogenide layer may comprise a metal oxide, a metal sulfide, a metal selenide, or a combination thereof. The intermediate metal chalcogenide layer may be formed on the surface of the negative electrode current collector by exposing the surface to a chalcogen in gas phase. Then, the lithium metal negative electrode layer may be formed on the surface of the negative electrode current collector over the intermediate metal chalcogenide layer by contacting at least a portion of the metal chalcogenide layer with a source of lithium such that the lithium actively wets the metal chalcogenide layer and forms a conformal lithium metal layer on the surface of the negative electrode current collector over the metal chalcogenide layer.
