Abstract
An electrochemical cell is presented having a pressure dissipation assembly that reversibly ceases cell operation when the internal cell pressure reaches a predetermined threshold. If, once the pressure dissipation assembly is activated, the internal pressure continues to increase to a second threshold, a venting mechanism is activated to release pressurized cell contents from the cell.
