Are lithium-ion battery energy storage systems fire safe?

With the advantages of high energy density, short response time and low economic cost, utility-scale lithium-ion battery energy storage systems are built and installed around the world. However, due to the thermal runaway characteristics of lithium-ion batteries, much more attention is attracted to the fire safety of battery energy storage systems.

Can a lithium-ion battery energy storage system detect a fire?

Since December 2019, Siemens has been offering a VdS-certified fire detection concept for stationary lithium-ion battery energy storage systems.* Through Siemens research with multiple lithium-ion battery manufacturers, the FDA unit has proven to detect a pending battery fire event up to 5 times faster than competitive detection technologies.

Are lithium-ion batteries a fire suppression solution?

Lithium-ion battery technology has become a standard solution in this application due to its technical performance. However, its unique fire hazard is a concern in the industry, increasing the need for dedicated lithium-ion battery fire suppression solutions.

What are Lib fire extinguishing agents?

LIB fire-extinguishing agents are generally solid, liquid, or gaseous. The Federal Aviation Administration employs an external flame jet to heat the battery, replicating the TR and fire behaviour of the battery under extreme conditions.

Which fire extinguishing agents are used for battery fires?

Based on the understanding of fire extinguishing mechanism, new fire extinguishing agents have been developed for battery fires, such as hydrogel fire extinguishing agents and liquid nitrogen fire extinguishing agents.

How can automatic fire-extinguishing systems improve fire suppression efficiency?

Simultaneously, the deployment of automatic fire-extinguishing systems, such as aerogel-based intelligent portable fire-extinguishing equipment, can swiftly activate fire suppression measures upon fire detection, thereby enhancing fire-extinguishing efficiency.
