Abstract:
The disclosed technology relates to an electrical feedthrough for a battery cell. The electrical feedthrough may include a rivet, an outer gasket, an inner gasket, a terminal and an insulator. The rivet compresses the outer gasket, inner gasket, and terminal to create a hermetic seal at an opening through an enclosure of the battery cell. The inner gasket includes a recessed portion for seating of the terminal to prevent rotation of the terminal with respect to the inner gasket, a protrusion for engaging a corresponding notch on the terminal to further prevent rotation of the terminal with respect to the inner gasket, and a mating surface for attaching to the insulator to align and position the insulator within the enclosure. The insulator is positioned between the battery cell and the inner gasket to prevent physical and electrical contact between the set of layers and the feedthrough.
