“…TR exhibits multiple propagation modes in large-scale systems, including horizontal TRP, vertical TRP, and fire propagation. Current numerical investigations into TRP have primarily focused on horizontal propagation within a single battery module, 79 , 101 , 103 , 106 , 107 , 110 , 113 , 115 , 122 with modeling of vertical TRP and subsequent fire propagation being relatively rare. A key challenge in these models is accurately coupling the TRP and combustion processes to capture their complex interactions.…”

“…Abuse (overcharge, internal short circuit and external short circuit, hot stove) will accelerate the generation of internal heat of LIBs, and lagging of heat transmission will cause rapid accumulation of internal heat of the battery, which will eventually lead to thermal runaway of the battery [18][19][20][21][22][23]. By studying the decomposition and mutual reactions of various components in the battery, it can be seen that the thermal stability of LIB materials is the basis of safety [24][25][26][27].…”

“…1,2-dimethyl-hydrazine could be found in 100% SOC LFP batteries. Under the intense thermal runaway process, cyanide compounds in the electrolyte additive decomposed into ammonia, which reacted with the ketones produced by the electrolyte decomposition to undergo a ketazine reaction and which hydrolyzed to obtain hydrazine (as shown in Formulas (20) and ( 21)) [58]. Trichlorotoluene in flame-retardant additives underwent hydrolysis at high temperatures to form benzoyl chloride (as shown in Formula ( 23)) [59].…”

Toxicity, emissions and structural damage results on lithium-ion battery (LIB) thermal runaway triggered by the electrothermal method were performed in this work. The electrothermal triggering method was determined to study the thermal runaway behaviors of three types of commercial LIBs. The structural damage of the cathode material of the batteries after thermal runaway was observed by scanning electron microscope (SEM), transmission electron microscope (TEM) and X-ray diffraction (XRD). It was found that as the state of charge (SOC) of the battery increases, the lower the temperature at which thermal runaway occurs, and the more badly the structural damage of the electrode material after thermal runaway. Qualitative analysis of products from LIBs thermal runaway emissions was conducted by GC-MS, and the toxicity and formation mechanism of the emissions were analyzed in detail. Dozens of toxic substances were detected from the emissions after thermal runaway of batteries using LixNi1/3Co1/3Mn1/3O2 and LiCoO2 as the cathode material, the types of toxic substances increase gradually with the increase in the SOC, while as for batteries using LiFePO4 as the cathode material, most types of toxic substances were detected from 30% SOC.

As an important component of new energy vehicles, the safety of lithium-ion batteries has attracted extensive attention. To reveal the mechanism and characteristics of ternary lithium-ion batteries under different trigger modes, an experimental system was established. The effects of different trigger modes on battery surface temperature, battery internal temperature, injection time, and battery voltage were analyzed. Among them, acupuncture, overheating, and overcharging are used as trigger conditions for mechanical, thermal, and electrical abuse. The results show that the injection time and surface peak temperature are positively correlated with the energy input before thermal runaway. Before the cell triggers abuse, the more input energy, the higher the cell surface temperature, the more serious the thermal runaway, and the higher the damage to the surrounding battery system. Under the same conditions, the intensity and damage degree of overcharge thermal runaway are greater than those of internal short circuit and overtemperature. The abnormal change of voltage suddenly rising and rapidly falling can be used as a condition to judge whether overcharge thermal runaway occurs. Finally, according to the temperature curves at different positions, the thermal diffusion law under different abuse conditions is summarized, which provides a basis for the safety design of the battery module.
