Electrochemical energy storage fire extinguishing in San Salvador

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.

Are large-scale fire extinguishing experiments necessary?

Therefore, before the fire extinguishing agent is used in energy storage stations, large-scale fire extinguishing experiments are necessary to truly evaluate the effectiveness and authenticity of the fire extinguishing agents and methods.

What is fire extinguishing agent immersion suppression?

However, the area of fire extinguishing agent attached to the battery surface is small, and the cooling effect is insufficient. Fire extinguishing agent immersion suppression is also a new method of battery thermal runaway suppression. The battery module is immersed in some media (silicone oil, HFE_7100 and water) .

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.
