| Abstract | Water mist (WM) with superior cooling capabilities is utilized to suppress thermal runaway (TR) and its propagation (TRP) of lithium-ion batteries (LIBs). However, its suppression effectiveness is influenced by various parameter settings, including activation time, release duration, release height, etc. Based on this, this work investigates the influence of the above parameter settings on the suppression of TR by WM. Specifically, releasing WM before irreversible TR occurs can effectively prevent the onset of TR. Additionally, the optimal duration of releasing WM is determined via fitting WM’s suppression and utilization efficiency. The results show that the optimal duration is approximately 3/4 of the TR duration, characterized with high suppression efficiency, high WM utilization, and low short-circuiting risk of the battery. Moreover, an equivalent experiment is designed to quantitatively evaluate the effectiveness of WM in suppressing TRP. Through calculating the internal energy change of the aluminum block, it is verified that releasing WM with the optimal duration can prevent TRP between battery packs. Concurrently, the suppression mechanism of WM on TRP is revealed. Moreover, the impact of WM on the smoke hazards from battery TR is assessed using the Fractional Effective Dose (FED) and Fractional Effective Concentration (FEC) models. This work can inspire the construction of a superior firefighting system, ensuring the process safety of LIBs in practical engineering. |
