University of Surrey Develops Smart Sensors for Lithium-Ion Battery Safety

According to foreign media reports, researchers at the University of Surrey have invented a new type of smart sensor that can help detect dangerous faults inside lithium-ion batteries, preventing them from escalating into fires or explosions. Lithium-ion batteries are central to the global transition to electric vehicles and renewable energy, but when they fail, the consequences can be catastrophic. Unlike current sensors that are located outside the battery and react slowly, the advanced sensors from the University of Surrey are embedded directly inside the battery, allowing for real-time monitoring of temperature, pressure, stress, and chemical changes, providing early warnings and even triggering built-in fire extinguishing functions.
