In this way, the mechanism of pressure effect on thermal runaway is revealed, which is a significant addition to the literature and helps to improve the fire safety of battery piles during storage and transport. Yanhui Liu: Data curation, Investigation, Writing − original draft, Formal analysis.
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.
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. Conclusions In this work, the thermal-runaway behaviors of 30% SOC LIB piles at the ambient pressure ranging from 20 kPa to 100 kPa were investigated in a novel low-pressure chamber. The battery failure process was separated by two important moments of safety venting and thermal runaway.
Mitigating internal short circuits is the most obvious method to prevent thermal runaway. Modification of the electrolyte, the separator, and the lithium anode will be discussed in more detail in the next chapter. The mechanism of internal short-circuiting is extremely complicated.
Thermal runaway mitigation by the proposed mechanism To identify the oxygen pathway in the presence of both the electrolyte and anode, which is the real scenario in a full cell, the mixture of Ca+An+Ely sample was prepared.
