Abstract
Systems and methods for responding to in a battery. A battery cell for a battery system includes a core of a known battery type, and a cell film having an initial thickness, the cell film configured as a pouch enclosing the core. The battery cell has at least one engraved groove in the cell film, the at least one engraved groove characterized by a groove thickness that is less than the initial thickness. The groove thickness configured to break open responsive to a predetermined gas pressure or target temperature in the pouch.
