Our previous study found liquid nitrogen (LN) exhibits excellent cooling performance for the TR batteries without damage to normal batteries, and can successfully suppress the TR of 100 % SOC batteries at 172.2 ℃, which is about 20 ℃ lower than the TR trigger temperature (Huang et al., 2021 ).
This study explores, experimentally, the effectiveness of liquid nitrogen (LN) in suppressing TR in 65 Ah prismatic lithium iron phosphate batteries. We analyze the impact of LN injection mode (continuous and intermittent), LN dosage, and TR development stage of LIB (based on battery temperature) at the onset of LN injection.
However, the application of LN on suppressing TR and cooling of LIBs has never been reported. In this work, a series of experimental studies were conducted to investigate the suppression and delay effect on the TR of the LIBs with various SOCs and figure out the cooling effect of LN on 100%SOC batteries.
