Fire Prevention, Detection and Suppression for Lithium Energy Storage
Introduction
While modern lithium chemistries (e.g., LiFePO₄) are safer, fire risk still exists under fault or abuse conditions. Effective fire safety combines prevention, early detection, and an appropriate suppression strategy.
Prevention Through Design
- Segregate battery banks and provide fire-rated containment zones.
- Avoid storing flammable materials in battery rooms and enforce hot-work permits.
Detection Systems
- Use multi-sensor detection: smoke/particulate detectors, aspiration (VESDA) systems for early particulate detection, and temperature rate-of-rise sensors.
- Place detectors both inside battery cabinets (if allowed) and in room ceilings/perimeter.
Suppression Options & Considerations
- Sprinkler systems can be effective but require coordination with electrical shutdown to avoid shorting risks.
- Clean-agent suppression (e.g., Novec 1230, FM-200) may protect surrounding equipment but will not prevent propagation within a failing cell pack; evaluate manufacturer guidance.
- Water mist systems offer cooling and flame knockdown with reduced water volume.
Integration & Automatic Isolation
- Tie suppression activation to automatic disconnects and BMS forced shutdown to cut off energy sources during fire events.
- Ensure safe venting paths for hot gases and smoke.
Training & Drills
- Regularly train facilities staff and first responders on battery fires — suppression differs from ordinary electrical fires.
- Maintain PPE, clear evacuation routes, and an incident action plan.
Conclusion
A layered approach — design, early detection, appropriate suppression, and trained response — is vital to mitigate fire risks in lithium energy storage facilities.
