Battery package with integral disconnect mechanism PAT 02-25-03 06524741 NDN- 217-0467-0321-0 INVENTOR(S)- Bryan, Aiden PATENT NUMBER- 06524741 PATENT APPLICATION NUMBER- 645275 DATE FILED- 2000-08-24 PATENT DATE- 2003-02-25 NUMBER OF CLAIMS- 8 EXEMPLARY CLAIMS- 1 FIGURES- 8 ART/GROUP UNIT- 1745 PATENT CLASS- Invention (utility) patent INVENTOR COUNTRY/ZIPCODE- IEX PATENT ASSIGNEE(S)- Valence Technology , Inc. ASSIGNEE CITY- Henderson ASSIGNEE STATE- NV ATTORNEY, AGENT, OR FIRM- Williams, Roger A.; Kovacevic, Cynthia A.; Ross, Michael D. U.S. PATENT CLASS- 429061000O U.S. CLASSIFICATION REFS.- X429162000; X429053000 INTERNATIONAL PATENT CLASS- 7H01M00202 PATENT REFERENCE(S)- 4997732; 5300373; 5405715; 5445856 FOREIGN DOCUMENT REFERENCE(S)- WO 97/08769 FOREIGN COUNTRY CODE- WOX A battery package assembly comprises a package having an interior volume sealingly containing at least one electrochemical cell therein, and opposite polarity electrical connectors adapted to connect said at least one electrochemical cell to an external load. At least one of the opposite polarity electrical connectors is adapted to automatically shut down the battery in response to a sufficient increase in internal pressure within the battery package. EXEMPLARY CLAIMS- 1. 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.
