Fire extinguishing system diagram of lithium battery energy storage station

How to extinguish a lithium ion cell fire?

In fire extinguishing tests the single cell was heated up to a temperature of about 650°C and then the extinguishing agent was applied. Carbon dioxide, foam, dry powder, pure water, and water mist were used to extinguish the Li-ion cell fires. For the battery pack fire, water was used as extinguisher.

How do li-ion batteries behave in fire conditions?

From a fire protection point of view, these two properties combined have created a whole new challenge: in fire conditions, Li-ion batteries behave in a fundamentally diferent way than batteries with water-based electrolyte. (cathode) and a negative electrode (anode).

What is the best fire extinguishing agent for lithium batteries?

With reference to the fire extinguishing agents of lithium cells/batteries, currently they include mainly water, foam, dry powder, carbon dioxide and water mist. The results of tests have shown that the most effective are water and foam.

What happens if a lithium ion storage system fires?

Loss of assets: a fire in a lithium-ion storage system that is not detected and dealt with in its incipient phase can easily lead to an uncontrollable event and may even lead to the complete loss of assets. Loss of revenue: any fire-related incident can lead to operational interruptions and consequential loss of revenue.

Do li-ion batteries need fire protection?

Marine class rules: Key design aspects for the fire protection of Li-ion battery spaces. In general, fire detection (smoke/heat) is required, and battery manufacturer requirements are referred to in some of the rules. Of-gas detection is specifically required in most rules.

Do lithium batteries cause thermal runaway?

In the case of the battery pack, it was observed that cell thermal runaway causes thermal runaway in the adjacent cells.The study on fire extinguishing agents and fire prevention technologies for lithium batteries has become an important part in the field of fire science.
