FAQS

Are lithium-ion batteries a fire hazard?

Battery Energy Storage Systems must be carefully managed to prevent significant risk from fire—lithium-ion batteries at energy storage systems have distinct safety concerns that may present a serious fire hazard unless proactively addressed with holistic fire detection, prevention and suppression solutions.

How can a battery management system reduce the risk of a fire?

To mitigate these risks, measures such as the use of a battery management system (BMS), installation of gas and fire detection and suppression systems, safe storage and disposal practices, adequate ventilation, regular inspection and maintenance, and proper emergency procedures are vital.

Can a Li-ion battery cause a fire?

Thermal runaway, a process involving a series of exothermic reactions within a Li-ion battery, can trigger a fire. Thermal runaway can occur when a Li-ion battery overheats due to various factors such as internal short circuits, mechanical damage, external heating, overvoltage during charging, or failure of the battery management system.

How does battery cell technology affect fire risk?

At the most fundamental level, the battery cell technology plays the key role in determining the fire risks involved : Some cell chemistries may go into thermal runaway at lower temperatures than others, and some chemistries will inherently produce less heat.

How can lithium-ion battery fires be prevented?

It is vital to adopt appropriate measures to prevent and mitigate lithium-ion battery fires. Some of these measures include: Implementing safe storage and disposal practices that avoid stacking or crushing the batteries and separate them from other flammable materials. This is particularly relevant for batteries in handheld devices

Why are lithium-ion battery fires difficult to quell?

Due to the self-sustaining process of thermal runaway, Lithium-ion battery fires are also difficult to quell. Bigger batteries such as those used in electric vehicles may reignite hours or even days after the event, even after being cooled. Source: Firechief® Global
