Summary: Most current models for battery thermal runaway only consider the heat generated inside the battery cell and neglect the effects of jet fire, which hinders the evaluation of thermal runaway propagation in a battery pack. This study proposes a coupled model that takes into account both the heat generation inside the battery and the jet fire outside during thermal runaway, providing a more accurate assessment of the thermal hazard. Experimental and simulation activities are conducted to validate the model's performance.

Summary: This study demonstrates that two endogenous oxygen pathways involved in strong exothermic reactions lead to uncontrollable states in the NMC811|graphite pouch cell, with significant safety concerns. Approximately 41% of thermal-induced oxygen reacts aggressively with ethylene carbonate at the cathode/electrolyte interface, accelerating the self-heating rate and triggering thermal runaway. The residual oxygen that survives the reaction with carbonate spreads to the lithiated anode, generating major heat and bringing the battery to the maximum destructive temperature during thermal runaway.

Summary: Thermal runaway is a critical issue for the large-scale application of lithium-ion batteries. This study investigates the exothermic reactions between lithiated graphite and electrolyte in lithium-ion batteries, revealing the roles of different components in the reactions. The reactions between lithiated graphite and different components result in three exothermic peaks, with the reactions with LiPF6 and ethylene carbonate contributing to the first two peaks, and the reaction with the binder contributing to the third peak. The quantitative relationship between lithiated graphite and electrolyte during the exothermic reactions is also explored. The findings of this study provide useful guidance for improving the safety of lithium-ion batteries.
