Abstract: A bi-metal tab includes an internal tab segment that can be coupled to a battery cell terminal within an interior of the cell and an external tab segment that can be coupled to an element external to the cell. One tab segment includes a pin tab segment that comprises a pin, and another tab segment includes a socket tab segment comprised of a separate metal material, that comprises a socket. The socket can be at least partially enclosed, on at least two opposing sides, by the structure of the socket tab segment, and the socket and pin of the separate segments can be configured to couple, to form the tab, where at least two surfaces of the pin are in flush contact with the socket tab segment structure. A protection layer that restricts electronic transport across the tab based on exposure to particular physical conditions can be included between the tab segments.
