Retention barrier assemblies are provided for traction battery packs. The retention barrier assemblies may be multi-layered and multi-functional sandwich structures that include foam, insulation, a backer plate, and adhesive. The retention barrier assemblies serve numerous functions including but not limited to retaining/holding down battery cells within a cell stack, shielding portions of an enclosure assembly from thermal energy created when one or more battery cells release battery vent gases and/or other effluents during a battery thermal event, and controlling the flow of battery vent byproducts in the event of such a battery thermal event as part of a vent management strategy.
