CURRENT INTERRUPT DEVICE FOR BATTERIES

摘要

The invention is a battery containing at least one electrochemical cell having a sealing plate with a pressure relief vent, the sealing plate being part of an electrical circuit between one of the electrodes and the corresponding terminal under normal conditions but capable of changing shape to break the circuit without the cell venting when the temperature of the sealing plate rises to a predetermined level and then returning to its original shape to reestablish the broken circuit when the sealing plate temperature returns to a normal level.
