According to the current situation of traditional foam fire extinguishing equipment, the design concentration of type AB FireIce extinguishing agent is 6%. Therefore, the concentrations of F-500 and FireIce were used at 3% and 6% for LFP battery fires, respectively, as shown in Fig. 1 (f), (g) and (h).
By analyzing the extinguishment, reignition, as well as temperature changes on the battery surface and in the vicinity of the safety valve, the efficacy of the extinguishing agent under real circumstances of a lithium iron phosphate battery fire was investigated, using different loading of FK-5-1-12.
Conclusions This work systematically investigated the extinguishing effects and mechanisms of gaseous extinguishing agents such as HFC-227ea and C 6 F 12 O and water-based extinguishing agents including the water mist with various additives on 243 Ah LFP battery 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.
Nowadays, an effective and clean extinguishing agent or technology is highly desirable for lithium-ion battery (LIB) fires. Herein, the physicochemical properties and extinguishing effects of various extinguishing agents on 243 Ah lithium iron phosphate (LFP) battery fires are investigated systematically.
It is a challenge to explore an efficient fire-extinguishing agent for LIBs fire. Meng et al. (2020) experimentally studied the suppression efficiency of ABC dry powder on LFP battery fires. They found that the open flame could be rapidly put out by dry powder, but the battery is likely to reignite.
