Abstract
The present disclosure relates a temperature regulating system including an anisotropic material for use as a heating material or element (e.g., an active heater) and a cooling material or element (e.g., passive cooling) in a battery pack including one or more electrochemical cells. The temperature regulating system includes one or more temperature control elements. Each temperature control element is configured to be in a heat transfer relationship with one or more electrochemical cells so as to heat and/or cool the one or more electrochemical cells of the battery pack. Each temperature control element includes two or more structural elements and one or more anisotropic elements disposed between the two or more structural elements. The temperature control elements may be disposed between the electrochemical cells of the stack, disposed around the electrochemical cells of the stack, or both.
