The ability to control heat transport with electrical signals has been an outstanding challenge due to the lack of efficient electrothermal materials. Previous attempts have mainly concentrated on low-thermal conductivity materials and encountered various problems such as narrow dynamic range and modest on/off ratios. Here, using high-thermal conductivity graphite films, we demonstrate an electrothermal switch enabling electrically tunable heat flow at the device level. The device uses reversible electro-intercalation of ions to modulate the in-plane thermal conductivity of graphite film by more than 13-fold via tunable phonon scattering, enabling observable modulation of the thermal conductivity at the device level. We anticipate that our results could provide a realistic pathway for adaptive thermal transport, enabling electrically driven thermal devices that would find a broad spectrum of applications in aerospace and microelectronics.
