According to the characteristics of LIBs fire discussed above, an ideal fire-extinguishing agent for LIBs fire should exhibit the following properties: high heat capacity to cool the batteries and rapidly extinguish flame, electrically insulating to prevent the short circuit of the battery during fire extinguishment, a highly wettability and a ...
Generally, the battery pack arrangement is tight to increase the system volumetric energy density, which makes the fire-extinguishing agents hard to access to the inner of the battery pack. Therefore, the deep-seated and inaccessible fire is difficult to be extinguished.
Many fire extinguishers are unsuitable for extinguishing lithium-ion batteries due to the high risk of dangerous chemical reactions and re-ignition. Thanks to their unique properties, our aerosol generators do not have these problems. Our systems can be used for the protection of production, storage and transport.
Screening tests for battery fire extinguishing agents were also performed. The effectiveness of an agent was evaluated through experiments on the cooling effect of fire extinguishing agents. Among the various agents, water and foam were found to be the most effective. 1. Introduction
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.
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.
Finally, their effectiveness in suppressing the fire were summarized. Water-based fire-extinguishing agents possess high cooling capacity and excellent anti-reflash performance for the fire. We believe this review could shed light on developing an efficient fire-extinguishing agent particularly designed for LIBs.
