Abstract: Devices that convert heat into electricity, and methods for a fabrication of the same are provided. The asymmetric thermo-electrochemical capacitor uses a GO-based positive electrode and a battery-type negative electrode to open up the operating voltage window and enhance the electrical discharge capacity for converting low-grade heat into electricity with excellent efficiency, fast thermo-charging time, and stable cycles. The thermo-electrochemical device includes a carbon-based positive electrode, a conductive polymer or a metal-organic framework as negative electrode, a current collector, and a porous separator.
