Abstract
A battery cell includes a cathode element, an anode element, and an electrolyte disposed in contact with each of the cathode and anode elements. The battery cell also includes a battery cell case constructed from a rigid material and defining an internal chamber configured to house each of the cathode element, the anode element, and the electrolyte. The battery cell case defines at least one aperture configured to provide a gas path between the internal chamber and an external environment. The battery cell additionally includes a reversible, multiple-use valve assembly mounted to the battery cell case and configured to selectively open a fluid flow through the at least one aperture to relieve a gas pressure within the internal chamber exceeding a predetermined pressure threshold.
