Abstract
A battery module includes one or more battery cells and one or more laminated elements configured to provide passive management of heat generated by the one or more battery cells. Each laminated element includes one or more heat conducting layers and one or more intumescent layers. The one or more intumescent layers are configured to expand in response to an intumescent layer temperature exceedance to reconfigure the laminated element from a first configuration in which the laminated element transfers heat emitted by the one or more battery cells to a second configuration in which the laminated element does not substantially transfer heat emitted by the one or more battery cells.
