What is Thermal Runaway?
Thermal runaway is a dangerous, self-accelerating reaction within battery systems (commonly lithium-ion batteries) where excessive heat triggers chemical reactions, releasing more heat, leading to:

Rapid temperature rise

Gas release (flammable or toxic gases)

Smoke, fire, or explosion

Why It's Critical for Fire Safety
✅ Early Warning to Prevent Catastrophic Fires
Thermal runaway progresses rapidly, often within seconds to minutes. Early detection allows:

Timely system shutdown

Activation of fire suppression

Evacuation alerts

Prevention of battery explosions

✅ Essential in High-Risk Environments
Thermal runaway is a major fire risk in:

Electric Vehicles (EVs)

Energy Storage Systems (BESS)

Consumer Electronics (laptops, smartphones)

Industrial Backup Systems

Aerospace & Robotics

These applications involve dense battery packs, making them vulnerable to overheating and fires.

✅ Multi-Sensor Detection Improves Safety
Thermal runaway detection combines:

Gas Sensors: Detect early off-gassing (e.g., hydrogen, VOCs)

Temperature Sensors: Monitor abnormal heat buildup

Smoke Sensors: Identify combustion byproducts

Pressure Sensors: Detect swelling or venting

MEMS-based gas sensors for hydrogen or VOCs often serve as the first alert, before visible smoke or fire occurs.

Conclusion
Thermal runaway detection is a frontline defense in fire safety, enabling early intervention and preventing loss of life, equipment damage, and large-scale fires, especially as battery-powered technologies become more widespread.
