Thermal runaway of Li-ion batteries is the phenomenon of exothermic chain reactions within the battery. These reactions usually cause a sharp increase in the internal battery temperature causing the inner structures of the battery to destabilize and degrade, which can lead to the total failure of the battery.
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.
5.1. Thermal runaway mitigation mechanism Thermal runaway in a battery pack can lead to fire hazards. The fire occurs when the mixture of battery fuel and oxidizer is exposed to high heat sources. The combustion can be halted through the following mechanisms: There are five types of basic extinguishants used to extinguish battery fires.
As thermal runaway is a major safety concern, therefore, the mathematical and numerical models are summarized, which are required to predict and develop the safety behaviors of batteries and optimize the battery thermal management system designs to prevent thermal runaway.
The thermal runaway of lithium-ion batteries is the phenomenon of chain exothermic reactions within the battery. These reactions cause a sharp rise in the internal battery temperature causing the inner structures of the battery to destabilize and degrade, which eventually leads to the failure of the battery.
Once the thermal runaway is triggered at the battery level by one of the mechanisms stated in the previous section, it is then propagated throughout the EV battery pack.
