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.
