Li-ion Batteries – 4 Phases of Failure
Lithium-ion energy storage systems have become increasingly popular due to their impressive energy density and long life. However, one of the major risks is the potential for thermal runaway, a condition where internal temperature rises rapidly, gases are emitted, and pressure increases—potentially leading to explosions or fires.
Stage 1:
Continuous monitoring of environmental conditions, mechanical stress, power fluctuations, and thermal parameters. The REL-iON platform detects anomalies to prevent issues and extend battery life.
Stage 2:
Before thermal runaway, venting gases due to pressure buildup signals early failure. Immediate reaction is crucial. REL-iON can detect CO₂ and electrolyte gases as early indicators.
Stages 3 & 4:
If a fire starts, Kidde Fire Systems' smoke detection and fire suppression products protect assets and minimize business disruption.
Multi-Point Monitoring Architecture
Reducing thermal runaway risk involves detecting off-gases. Ideal sensors detect both CO₂ and VOCs (Volatile Organic Compounds).
For liquid-cooled batteries, a Hydrogen (H₂) sensor is vital, as H₂ gas can leak during normal operation before any other gas is released.
