  • Publication number: 20230059842
    Abstract: A method of manufacturing an all-solid-state battery cell includes depositing an interlayer directly onto an anode current collector; depositing a solid electrolyte onto the interlayer opposite the anode current collector; forming a cathode on the solid electrolyte opposite the interlayer, wherein the cathode contains one or more lithium-containing compounds; and applying pressure to achieve uniform contact between layers. The manufactured all-solid-state battery cell is anode-free prior to charging. The interlayer is configured such that lithium metal is deposited between the interlayer and the anode current collector during charging, the interlayer prevents contact between the lithium metal and the solid electrolyte, and the interlayer has a greater density than a density of the solid electrolyte.
