Abstract: Some embodiments disclosed herein are directed to connectors for thin-film functional separators in battery cells. In accordance with an exemplary embodiment, a thin-film functional separator for a battery cell is provided. The thin-film functional separator may be disposed within the battery cell, such as between a cathode and anode of the battery cell. The thin-film functional separator includes a porous composite membrane that includes a microporous substrate and a coating layer, and includes a lead extending from the porous composite membrane. The lead extending from the porous composite membrane is coupled to an external conductive tab using a mechanical connector that electrically couples the external conductive tab to the lead extending from the porous composite membrane. Other embodiments may be disclosed or claimed.
