<ul><li>A new sensor has been developed to detect and prevent overheating of lithium-ion batteries.</li><li>The sensor detects trace amounts of ethylene carbonate (EC), a key component of battery electrolyte.</li><li>Using covalent organic frameworks (COFs), the sensor is highly sensitive and can detect EC vapour at low concentrations.</li><li>By detecting potential failures early, the sensor can contribute to safer battery management systems and prevent catastrophic incidents.</li></ul>
