Energy storage battery fire extinguishing method

Should foam extinguishing agent be used in energy storage stations?

DNV GL did not recommend the use of foam extinguishing agent in the fire of energy storage stations because the battery module fire required rapid cooling to dissipate heat. Compared with water, foam had more difficulty penetrating the gap of battery packs and cooling the insides of batteries.

What is the mechanism of fire-extinguishing agent?

The mechanism of fire-extinguishing agent is mainly divided into isolation, smothering, cooling and chemical suppression. However, the fire triangle of battery is difficult to destroy, as the three elements of fire triangle can be provided by the battery itself. In addition, LIB fire is a complex fire with the characteristics discussed above.

Can water be used to extinguish a battery fire?

Reif et al. suggested that water should not be used to extinguish the battery fire since the reaction between water and lithium metal would generate flammable and explosive H 2, instead they recommended using a dry powder extinguishing agent to extinguish the fire. In addition, the cooling methods for water and dry powder are different.

How to extinguish Lib fire?

With excellent cooling effect, water injection is the most effective way to extinguish LIB fire [25, 105, 110]. However, due to the conductivity and corrosivity of water, there may still be a risk for cells (re)igniting after some time, especially the high voltage battery module.

Should lithium-ion battery fire extinguishing agent be developed?

Therefore, based on this article, it is worth developing a new type of lithium-ion battery fire extinguishing agent that improves this fire extinguishing agent to have both good fire extinguishing effect and cooling performance. Gang Zhou: Supervision, Project administration, Funding acquisition, Conceptualization.

What makes a good fire extinguishing system?

An ideal fire extinguishing system should have excellent fire extinguishing and cooling effects, which can quickly extinguish open flames and reduce battery system temperature. Specifically, extinguishing systems whose aim it to prevent module-to-module, and beyond, propagation.
