ABSTRACT:
An electrochemical cell having a cell housing containing active components of the cell and having an inner cover and vent passage provided in the inner cover. A vent with a seal member is force-fitted within the vent passage. A current interrupt contact is provided on an outer cover and facing the seal member for providing electrical contact between the outer cover and a current path of the cell. Upon reaching a predetermined internal cell pressure, the seal member is forcibly released from the vent passage and, at the same time, forcibly engages the current interrupt contact to interrupt the flow of current from within the cell to the outer cover.
