  • Publication number: 20240243365
    Abstract: A battery cell of a solid-state battery, such as a solid-state traction battery of an electrified vehicle, includes first and second electrodes and a solid electrolyte sandwiched between the electrodes in a stack. The first electrode overhangs the second electrode in the stack. The solid electrolyte may have a surface area that is the same as the surface area of the first electrode with the solid electrolyte together with the first electrode overhang the second electrode in the stack. The battery cell may further include a current collector having a main portion and a tab region extending therefrom. The current collector is arranged in the stack with the second electrode sandwiched between the main portion of the current collector and the solid electrolyte and with the first electrode overhanging the tab region of the current collector. An electrical insulation layer is applied to the tab region of the current collector.

  • Publication number: 20240243437
    Abstract: A battery cell of a solid-state battery, such as a solid-state traction battery of an electrified vehicle, includes first and second electrodes and a solid electrolyte. The solid electrolyte is assembled (e.g., laminated) to the first electrode and is sandwiched between the first electrode and the second electrode in a stack. The first and second electrodes have a same size surface, and the solid electrolyte has a surface no larger than the surface of the first electrode. An edge of the first electrode is coated with electrical insulating material. An edge of the second electrode and/or an edge of the solid electrolyte may also be coated with electrical insulating material. The first electrode may be an anode and the second electrode may be a cathode. Alternatively, the first electrode may be a cathode and the second electrode may be an anode.
