Abstract
The present disclosure provides a solid-state battery including at least one current collector that is in communication with one or more switches configured to move between open and closed positions, where the open position corresponds to a first operational state of the solid-state battery and the closed position corresponds to a second operational state of the solid-state battery; one or more electrodes disposed adjacent to the one or more current collectors; and one or more electrothermal material foils including a resistor material that is in electrical communication with that at least one current collector, where in the first operational state electrons may flow through the one or more electrothermal material foils during cycling of the solid-state battery so as to initiate a heating mode, and in the second operational state electrons may flow through the current collector during cycling of the solid-state battery so as to initiate a non-heating mode.
