HINGED VENT FOR ELECTROCHEMICAL CELL SYSTEM AND METHOD

摘要

The present disclosure includes an electrochemical cell having a housing configured to house one or more electrodes of the electrochemical cell. The housing includes a wall having an inner surface facing the one or more electrodes. The electrochemical cell also includes a hinged vent stamped on the inner surface of the housing, where the hinged vent includes a fracture portion, a hinge portion on either side of the fracture portion extending substantially parallel to the fracture portion, and connecting portions extending between the fracture portion and the hinge portions. The fracture portion includes a first cross-sectional width through the wall of the housing and the hinge portion includes a second-cross sectional width through the wall of the housing greater than the first cross-sectional width.
