Title: Low profile pressure disconnect device for lithium ion batteries

Abstract

Casings for lithium ion batteries are provided that include a container or assembly that defines a base, side walls and a top or lid, and a vent structure associated with the container or assembly. A flame arrestor may be positioned in proximity to the vent structure. The lithium ion battery may also include a pressure disconnect device associated with the casing. The pressure disconnect device may include a deflectable dome-based activation mechanism, and the deflectable dome-based activation mechanism may be configured and dimensioned to prevent burn through, e.g., by increasing the mass of the dome-based activation mechanism, adding material (e.g., foil) to the dome-based activation mechanism, and combinations thereof. Burn through may also be avoided, at least in part, based on the speed at which the dome-based activation mechanism responds at a target trigger pressure.
