Thermal Runaway Temperature Prediction of Lithium-Ion Battery Under Extreme High-Temperature Shock Using Experimental and Virtual Data.

ABSTRACT: The trend toward increasing energy density in lithium-ion batteries (LIBs) makes thermal safety more critical. However, traditional adiabatic calorimetry fails to simulate flame exposure in real fire incidents. Herein, a framework of the thermal runaway (TR) temperature prediction of LIBs is proposed using experimental and virtual data for extreme high-temperature shock conditions. Specifically, high-temperature shock wave-induced TR tests are conducted on LiNi_0.5Co_0.2Mn_0.3O₂ (NCM523) and LiFePO₄ (LFP) batteries to compare combustion behavior and TR characteristics, while obtaining realistic temperature data. A 3D conjugate heat transfer and TR coupling model is established, and characteristic temperature parameters of TR under this co
