The present disclosure is directed to a barrier wall between battery modules that comprises two or more of a structural element to resist impacts from vented objects during a thermal runaway of a cell, a thermally anisotropic material to transfer heat away from the thermal runaway away from the affected cell, and a fire-resistant material that is not only fire-resistant but also electronically non-conducting or insulating to inhibit electrical shorting between the affected cell and the structural element or thermally anisotropic material.
