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.
Thermal runaway threshold considerations for various battery application and abuse types are summarized. Thermal runaway of lithium-ion batteries (LIBs) remains a major concern in their large-scale applications. It has been a hot topic to understand the thermal runaway (TR) behavior of LIBs, with the goal of achieving early warning of TR.
Therefore, for the MO 2 metal oxides decomposition and the beginning of the third main reaction of the thermal runaway (51 + Rele), also need an internal battery temperature of at least 225 °C i.e. much higher than for the initiation of the first main reaction of the thermal runaway (21).
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.
The uncontrollable and irreversible nature of thermal runaway is the main challenge for the mitigation of Li-ion battery safety hazards. It has focused researchers’ attention on the prediction of thermal runaway behaviors to enable early warning or delays, to potentially prevent thermal runaway in Li-ion battery applications.
Therefore, for the LiC 6 decomposition and initiate the first main reaction of thermal runaway (19), the temperature of approximately 107 °C (for LCO batteries) is required. In the paper , it was shown that for the batteries with NMC cathodes, the first exothermic reaction of the thermal runaway starts at approximately 95 °C.
