This results in a sharp increase in the temperature of the battery and in launching of the second and third main reactions of the thermal runaway. Also the batteries' mechanical deformation can be a way to initiate the thermal runaway. The main purpose of the deformation is obtaining of internal short circuits of the electrodes.
Currently, in order to initiate the thermal runaway process in the lithium-ion batteries, three methods are used: a) batteries' overheating, b) mechanical deformation and c) batteries' overcharging.
However, the advancement of LIB technology is hindered by the phenomenon of thermal runaway (TR), which constitutes the primary failure mechanism of LIBs, potentially leading severe fires and explosions. This review provides a comprehensive understanding of the TR mechanisms in LIBs, which vary significantly depending on the battery’s materials.
Thermal runaway is a major challenge in the Li-ion battery field due to its uncontrollable and irreversible nature, which can lead to fires and explosions, threatening the safety of the public. Therefore, thermal runaway prognosis and diagnosis are significant topics of research.
Residual energy in the battery, the state of charge (SOC), energy released in a battery, and DOD: These parameters are related to the diffusion rate of lithium ions, which suggests that prevention of overcharge and overdischarge of the battery is a feasible approach to avoid thermal runaway.
The evaporating electrolyte and gases (released during the thermal runaway) form a gas plug at the spot of the thermal runaway, which (as it increases) interrupts the electrochemical reaction of the thermal runaway. The gas plug between the electrodes increases the internal resistance of the battery.
