“…The separator collapse temperature mainly determines T2; T3 represents the total thermal energy released from the battery failure, calculated by Equation ( 5). However, due to the significant temperature difference between the surface and the center, the temperature value acquired in the experiments is not precisely the accurate inner temperature [46]. Besides, self-heat generation temperature T1 cannot be detected in the experiments.…”

To analyze the impact of two commonly neglected electrical abuse operations (overcharge and overdischarge) on battery degradation and safety, this study thoroughly investigates the high current overcharge/overdischarge effect and degradation on 18650-type Li-ion batteries (LIBs) thermal safety. Based on the temperature-voltage behavior and induced thermal runaway (TR) mechanisms, the overcharge and overdischarge-triggered TR processes are divided into four and three stages. Furthermore, the degradation effect is analyzed by analyzing the incremental capacity-differential voltage curves. During the high current cycling process, lithium inventory decreases significantly. Besides, the active material decreases when the battery degrades to a certain level. Lithium plating is the primary reason for lithium inventory loss; the plated lithium grows with the increment of degraded/overcharged level. Besides, the dissolution and deposition affect the internal short circuit degree, which can be observed from the electrode potential and cell voltage value. Moreover, battery cells undergo different degradation degrees, and different current rates of charging/discharging exhibit similar temperature-rising trends during the adiabatic TR tests. However, with the degradation degree increase, battery capacity fades, TR becomes easier to be triggered by the high current rate, and TR reactions are severe. This study guides early quantitative detection, safer battery cell design, and enhanced thermal safety management.

“…However, the data-driven approaches [21,22] suffer the drawbacks of large data requirement and limited ability to capture unforeseen anomalies. The work in [27] shows that the surface temperature of pouch cells is a proper indicator for thermal runaway detection and is an appropriate replacement of internal temperature as well. However, sensor placement on cell concerning fault detection and isolation has not been investigated.…”

Safety against thermal failures is crucial in battery systems. Real-time thermal diagnostics can be a key enabler of such safer batteries. Thermal fault diagnostics in large format pouch or prismatic cells pose additional challenges compared to cylindrical cells. These challenges arise from the fact that the temperature distribution in large format cells is at least two-dimensional in nature (along length and breadth) while such distribution can be reasonably approximated in one dimension (along radial direction) in cylindrical cells. This difference makes the placement of temperature sensor(s) non-trivial and the design of detection algorithm challenging. In this work, we address these issues by proposing a framework that (i) optimizes the sensor locations to improve detectability and isolability of thermal faults, and (ii) designs a filtering scheme for fault detection and localization based on a two dimensional thermal model. The proposed framework is illustrated by experimental and simulation studies on a commercial battery cell.

“…During thermal runaway experiments, Xu et al found a significantly greater temperature rise was experienced internally when compared to that measured on the cell surface. At the peak of thermal runaway, the internal temperature of the cylindrical cell exceeded 1220 • C (compared to a surface temperature of only 600 • C), demonstrating the importance of measuring internal temperature, when investigating the onset of thermal runaway [16]. Previous works on cell instrumentation that include the experimental in-cell measurement of temperature are included in Table 1.…”

“…There have been previous reports of drilling into the aluminium can of cylindrical cells. For example in Xu et al [16] have reported drilling into the can of cylindrical cell. However, limited information is detailed regarding the methodology, and in particular, the steps taken to ensure that metal fragments or swarf do not enter the cell.…”
