Summary The nickel‐rich lithium‐ion batteries (LIBs) are widely used as the energy source of new energy vehicles. But the relatively poor safety performance results in serious accidents, which attracts more and more attention of researchers. In this study, the thermal runaway (TR) features of a pouch cell consisted of LiNi0.5Mn0.3Co0.2O2/graphite are investigated by an extended volume‐accelerating rate calorimeter combined with resistance monitoring, voltage monitoring, and video imaging technologies. Based on these techniques, the TR process is divided into five representative stages, that is, the start of self‐heating, the venting of flammable gas, the volatilization of electrolyte, the melt of separator, and the internal short circuit of LIBs. Besides, a lumped‐parameter thermal model with high precision is developed to predict and explain the TR process. The heat generated by the decomposition of solid electrolyte interface (SEI), the reaction of anode‐electrolyte, the multiple phase transition of the cathode is considered as the main heating source of TR. The resistance shows a higher sensitivity to the SEI decomposition than temperature does. The venting process along with the evaporation of electrolytes provides significant opportunities to obstruct the TR. The interval time between voltage drop and temperature rise is 6.9 seconds, which is beneficial for the early warning of TR.

Summary Lithium-ion batteries (LIBs) are widely used as the energy carrier in our daily life. However, the higher energy density of LIBs results in poor safety performance. Thermal runaway (TR) is the critical problem which hinders the further application of LIBs. Clarifying the mechanism of TR evolution is beneficial to safer cell design and safety management. In this paper, liquid nitrogen spray is proved to be an effective way to stop the violent reaction of LIBs during the TR process. Based on extended-volume accelerating rate calorimetry, the liquid nitrogen ceasing combined with non-atmospheric exposure analysis is used to investigate the TR evolution about LiFePO 4 /graphite batteries at critical temperature. Specifically, the geometrical shape, voltage, and impedance change are monitored during the TR process on the cell level. The morphologies/constitution of electrodes and separators are presented on the component level. Utilizing the gas analysis, the failure mechanism of the prismatic LiFePO 4 /graphite battery is studied comprehensively.

“…Different root causes can trigger this effect, such as cell mechanical abuse, thermal abuse or electrical abuse [ 2 ]. It evolves with a first phase of self-heat generation, that is considered consistent with the decomposition of the solid electrolyte interface [ 3 ], then a second phase is characterized by fast temperature rise to the maximum temperature [ 4 ]. Thermal runaway can be detected through a typical voltage drop 15–40 s before the overheating onset [ 5 ].…”

During the last decade, electric vehicles had a remarkable diffusion caused by Li-ion batteries lowered prices and improved performances. Meanwhile, incidents involving fire were reported for electric vehicles during charge operation or simple parking. The potential drawbacks of this technology could play a role on safety in the next years, especially for household or underground charge. This paper presents the development of a novel system concept based on a Vanadium-air flow battery, applied to provide charge and fire safety of electric vehicles through oxygen reduction in a sealed box. When the vehicle is parked inside the box and the passengers are outside of it, a nitrogen injection is operated to reduce the fire risk quickly, during the subsequent vehicle charge operation the oxygen is consumed from the box atmosphere by the cathode of the Vanadium-air battery that supplies energy, then the nitrogen reserve is restored consuming oxygen from the external ambient and the energy output can be supplied to smart grids. The system is mainly composed by the Vanadium-air flow battery, the protection box and the nitrogen reserve, it is sized relatively to the most diffused road and commercial electric vehicles for different values of on-board battery capacity and charge power Moreover, it can be integrated into vehicle-to-grid energy systems improving intersectoral flexibility.
