Abstract
An automotive battery module with one or more battery cells and a heat exchange member placed in thermal communication with the battery cell. Heat generated within the battery cell by, among other things, electric current that can be used to provide motive power for the automobile may be removed by the heat exchange member that is made up of a flexible substrate and one or more graphene layers disposed on the substrate. The construction of the substrate and graphene layer is such that multiple heat transfer paths are established, each defining different levels of thermal conductivity and related transfer of heat away from the battery cells.
