THERMAL SUPPRESSION CONTAINER DESIGNS FOR MANAGING THERMAL ENERGY WITHIN TRACTION BATTERY PACKS

Thermal suppression containers are provided for use within traction battery packs. An exemplary thermal suppression container may include an outer pouch and a thermal suppression agent releasably contained within the outer pouch. The thermal suppression container may be configured to release the thermal suppression agent when a temperature near the outer pouch exceeds a predefined temperature threshold. The thermal suppression agent may capture or trap particles associated with battery vent byproducts, thereby managing or even preventing the transfer of thermal energy to nearby structures. The outer pouch of the thermal suppression container may include one or more flag seals that are configured to position the thermal suppression container relative to surrounding structures.
