Lithium-ion batteries (LIBs) catch fire easily due to thermal runaway (TR). Fires following TR in LIBs pose a serious threat to public safety. Effective extinguishing methods for LIB fires have not been developed. In this work, the effect of a synergistic fire extinguishing method based on liquid nitrogen (LN) is evaluated for the suppression effect of LIB fires.

German motor vehicle inspection association (DEKRA) reported several kinds of water-based fire-extinguishing agents such as water, F-500 and a gelling agent used in extinguishing lithium-ion traction batteries fires. The flame of power LIBs was rapidly extinguished by 1% F-500 within merely 7 s.
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.
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.
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
For example, an extract of Annex C Fire-Fighting Considerations (Operations) in NFPA 855 states the following in C.5.1 Lithium-Ion (Li-ion) Batteries: Water is considered the preferred agent for suppressing lithium-ion battery fires.
