Traction battery pack cell stack designs for establishing sealed interfaces

Abstract

Battery cell stack designs are provided for traction battery packs. An exemplary traction battery pack may include one or more cell stacks housed within an enclosure assembly. Each cell stack may include a top cover and a thermal barrier assembly. The top cover is arranged to protect and interface with an enclosure cover of the enclosure assembly, and the thermal barrier assembly is arranged to inhibit the transfer of thermal energy across the cell stack. A first adhesive may secure a portion of the thermal barrier assembly to the top cover, and a second adhesive may secure the top cover to the enclosure assembly, thereby structurally integrating the traction battery pack.
