Thermochromic Gires‐Tournois Resonators with Tellurium for Battery Thermal Runaway Warning

open access: yesAdvanced Materials, Volume 37, Issue 40, October 9, 2025.
A thermochromic Gires‐Tournois (GT) resonator with a thin tellurium layer enables rapid, reversible, and untethered detection of battery surface temperature <80 °C. Exploiting tellurium's refractive index change driven by a thermally induced phase transition between solid and quasi‐liquid states, the GT resonator visualizes heat propagation, providing ...
