Thermal runaway propagation characteristics of lithium-ion battery modules in a restricted channel with different longitudinal wind velocities J. Power Sources (IF 9.2) Pub Date : 2024-02-25 Zhi Wang, Bo Yin, Qingjie Zhao, Weiguang An, Bobo Shi, Liyuan Jiang
Thermal runaway (TR) and its propagation (TRP) in lithium-ion batteries (LIBs) present safety challenges, especially in confined spaces where wind speed's impact on TRP remains poorly understood. This study investigates the influence of longitudinal wind speed on TRP in LIBs within restricted channels. Results reveal a decreased incidence of TR with higher wind speeds. At 0 m/s, all cells in the two
