“…Figure 7 provides a compilation of the overtemperature test results conducted on different types of cells at different SOC, published in the literature [51][52][53][54]. Figure 7a shows the relationship between temperature at the onset of TR (T 2 ) and the SOC, observing a decreasing trend as the SOC increases.…”

Lithium-ion batteries (LIBs) are becoming well established as a key component in the integration of renewable energies and in the development of electric vehicles. Nevertheless, they have a narrow safe operating area with regard to the voltage and temperature conditions at which these batteries can work. Outside this area, a series of chemical reactions take place that can lead to component degradation, reduced performance and even self-destruction. The phenomenon consisting of the sudden failure of an LIB, causing an abrupt temperature increase, is known as thermal runaway (TR) and is considered to be the most dangerous event that can occur in LIBs. Therefore, the safety of LIBs is one of the obstacles that this technology must overcome in order to continue to develop and become well established for uses in all types of applications. This chapter presents a detailed study of the general issues surrounding this phenomenon. The origin of the problem is identified, the causes are detailed as well as the phases prior to TR. An analysis is made of the most relevant factors influencing this phenomenon, and details are provided of detection, prevention and mitigation measures that could either prevent the TR or reduce the consequences.

“…Thermal runaway propagation in the battery pack is another crucial factor affecting the overall safety performance. In general, the means of propagation are also diverse 29 . The heat transfer between batteries mainly consists of three pathways: heat transfer through the battery shell, tab collector, and spreading of fire 30,31 .…”

Electrochemical energy storage is one of the critical technologies for energy storage, which is important for high-efficiency utilization of renewable energy and reducing carbon emissions. In addition to the higher energy density requirements, safety is also an essential factor for developing electrochemical energy storage technologies. Lithium-ion batteries (Li-ion batteries) are commercialized as power batteries in electric vehicles (EVs) because of their advantages (such as high energy density, long life span, etc.), while for future electrochemical energy storage markets, lithium-sulfur (Li-S) and lithium-air (Li-air) batteries can be promising candidates for high energy density requirements. Therefore, this paper summarizes the present or potential thermal hazard issues of lithium batteries (Li-ion, Li-S, and Li-air batteries).Moreover, the corresponding solutions are proposed to further improve the thermal safety performance of electrochemical energy storage technologies.

“…Recently, several researchers have studied the effect of SOC on battery safety behaviors [19][20][21] . Li et al [22] studied the thermal stability of lithium-ion batteries with 57 A•h silicon-carbon negative electrodes at different SOCs and found that a strong reaction occurs between the positive and negative electrodes when the SOC of the tested battery exceeds 50%.…”

To investigate the effect of different states of charge(SOC) on the thermal runaway(TR) propagation behaviors within lithium-ion-batteries based energy storage modules, an experimental setup was developed to conduct failure propagation tests on battery modules at an SOC of 97%, 85%, and 50%. The result indicates that an increase in the SOC of batteries can decrease the TR trigger temperature, making batteries trigger TR earlier and reducing the average failure propagation time between two adjacent cells.In addition, the failure propagation tests reveal that at higher SOCs, the TR reaction becomes more violent, the maximal reaction temperature is also much higher, and the damage to the battery module is severe. Compared to the battery module with 97% SOC, the TR trigger time of the battery module with 50% SOC was postponed by approximately 57.8%. Meanwhile, the average failure propagation time got prolonged by approximately 36.0%. Thus, this study can provide references for the thermal safety design of energy-storage battery modules.
