Lithium-ion energy storage fire extinguishing system

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.

Does Stat-X extinguish a lithium ion battery?

The Stat-X aerosol extinguishing product was tested for efficacy in suppressing Li-ion battery fires. It was found that the Stat-X agent successfully extinguished single and double cell battery fires. This testing was conducted in parallel with a large battery fire testing program.

Can a lithium battery fire be extinguished?

Thermal runaway in one cell can trigger a chain reaction, causing other cells to fail and intensify the fire. The combination of high energy density, reactive chemicals, thermal propagation, and potential hydrogen production makes lithium battery fires extremely challenging to extinguish.

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 does a battery fire extinguisher work?

When the high-temperature gas is emitted or burned, the tube melts and releases the fire extinguishing agent, thereby cooling the battery or extinguishing the fire in advance. In this way, a large amount of high-pressure fire extinguishing agent can be injected into the battery fire, which has a good fire extinguishing effect.

Does a battery fire extinguishing agent have a good effect?

In this way, a large amount of high-pressure fire extinguishing agent can be injected into the battery fire, which has a good fire extinguishing effect. However, the area of fire extinguishing agent attached to the battery surface is small, and the cooling effect is insufficient.
