Abstract:
A battery assembly for providing electrical energy to an external load, comprising:an expandable package containing an electrochemical cell therein; and opposing polarity electrical connectors in electrical communication with said electrochemical cell for electrically connecting said electrochemical cell to the external load, at least one of said electrical connectors comprising: an electrically conductive package tab associated with said package and movable therewith, and an electrically conductive cell tab associated with said electrochemical cell, said cell tab comprising a biased portion in interruptible electrical contact with said package tab, said cell tab biased portion movable from a biased position to an extended position; whereby when said package expands outwardly and said package tab moves therewith, said cell tab biased portion moves with said package tab while maintaining electrical contact therewith, and when said package further expands outwardly and said cell tab biased portion moves to said extended position, said package tab moves out of electrical contact with said cell tab biased portion, thereby rendering said battery assembly inoperative.
