“…To investigate the sidewall rupture behaviour of the high specific energy cells at different SOCs, this work adopted nail penetration test because it is one of the mechanical abuse tests and is widely adopted to evaluate the risk of TR of LIBs and to act as a trigger of TR initiation. [23][24][25][26][27][28][29] In addition, compared to external heating abuse and overcharge abuse conditions, nail penetration tests do not introduce additional energy to the cell. Therefore, in this work, a series of nail penetration tests was performed on 21700-format cells with a high specific energy and different SOCs.…”

To understand the relationship of the sidewall rupture at different state of charge (SOC) of cylindrical cells with high specific energy, this work presents the results of radial nail penetration tests of 21700 cylindrical cells at different SOC. The thermal runaway and sidewall rupture behaviours were characterised by key performance indicators such as temperature, mass, fire behaviour, and voltage change. In addition, released gases from a subset of tests were measured using the Fourier transform infrared spectroscopy. The change in the internal structure of another subset of cells after the test was observed by X-ray computed tomography. The results show that the sidewall rupture still exists for tests at low SOC (< 30% SOC), but the outcome of thermal runaway and sidewall rupture is milder than those at high SOC (≥ 50% SOC). The average mass loss of cells increases with the increment of SOC. The cell casing thickness is reduced by 12.7% ± 0.3% of the fresh cell, which in combination with the reduction in the strength of the casing material at high temperatures could contribute to sidewall rupture

“…Lithium-ion batteries (LIBs) have been commercialized for 30 years since 1991 ( Fleming, 2015 ; Wang et al., 2021a , 2021b ). Nowadays, LIBs are widely used as the energy storage devices for electronic products, vehicles, spacecraft, etc., owing to their relatively high power/energy density, long cycle life, no memory effect, and eco-friendly properties ( Dai et al., 2021 ; Zhang et al., 2021 ; Zheng et al., 2020 ).…”

“…The undesirable heat with a certain chance to result in TR could be triggered by mechanical abuse (crush, penetration, vibration, etc.) ( Duan et al., 2019 ; Wang et al., 2021a ), electrical abuse (overcharge, over-discharge, short-circuit, etc.) ( Ren et al., 2019a ), and thermal abuse (external heating, internal heating, etc.)…”

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.
