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.
Figure 6 shows that at this time point, the battery is in the second stage of thermal runaway. The voltage of 5.0 V falls within the first-level warning threshold (5.1 V to 5.5 V), the temperature of 50 °C is within the second-level threshold (48 °C to 55 °C), and the CO concentration of 2 ppm is outside the third-level threshold (2 ppm to 10 ppm).
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.
Thus, based on the established mechanism of the thermal runaway in the lithium-ion batteries and taking into account the three types of the random factors noted above, it is possible to explain the results of all currently known experimental studies on the heat release in the batteries during the thermal runaway.
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).
