    Abstract: A prismatic lithium ion battery cell includes a packaging having a cover sealed to a can, wherein the cover includes a reversal disk. A conductive member is disposed above the reversal disk and a power assembly is disposed within the packaging. A first terminal pad and a second terminal pad are disposed above the conductive member and respectively coupled to the power assembly. The reversal disk is configured to deflect upwards and to displace the conductive member to contact the first and second terminal pads in response to a pressure within the packaging being greater than a first predefined pressure threshold and thereby form an external short-circuit between the first and second terminal pads via the conductive member. Subsequently, a portion of the power assembly fails in response to the external short-circuit and interrupts current flow between the first and second terminal pads.
