Abstract
An electrochemical cell is presented having a first component that provides a seal to prevent the escape of internal cell ingredients from the battery and into the ambient environment during normal operation of the cell. A second component, independent of the first component, provides a vent and allows built-up pressure to dissipate when the pressure reaches a predetermined maximum threshold.
