A prismatic lithium ion battery cell includes a packaging having a cover. A power assembly disposed within the packaging has a first (e.g., negative) side and a second (e.g., positive) side. A terminal pad is electrically coupled to the first side, while the cover is electrically coupled to the second side, of the power assembly. The cover includes a spiral disk feature disposed below the terminal pad and a reversal disk disposed below the spiral disk feature. The reversal disk is configured to deflect upwards to displace the spiral disk feature to contact the terminal pad in response to a pressure within the packaging being greater than a first predefined pressure threshold, forming an external short-circuit between the first and second sides of the power assembly. Subsequently, a portion of the power assembly fails in response to the external short-circuit and interrupts current flow within the power assembly.
