Electrochemical cell with internal circuit interrupter |
摘要 |
Electrochemical cells employ a current collector-safety switch member comprised of a shape memory alloy in the electric circuit in the cell. The collector-safety switch member has a base portion and a plurality of legs extended therefrom and when the internal temperature of the cell rises, the legs of the collector-safety switch member are retracted to thereby disconnect the electrical circuit in the cell. These cells can also be comprised of a resettable thermal switch for inhibiting the flow of current in the cell at a temperature below the disconnect temperature of the current collector-safety switch member.
