“…Many studies have evaluated the effect of grouping batteries in series or parallel on TR and other failure propagation behaviors. The results show that in a parallel arrangement, current from a normal cell could flow through an adjacent damaged or low voltage cell, causing a TR and thus resulting in a less safe parallel module [8][9] than the ones in series [10] and unconnected modules [11] during the process of failure propagation.…”

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.

“…Ouyang et al discovered a significant domino effect in the TR spreading process of battery packs. Zhou et al investigated the design of battery modules with various connection modes to reveal the mechanism of TR propagation. Conventional BTMS cannot inhibit the spread of thermal runaway, but adding insulation materials to the battery module can effectively delay or even block its spread.…”

The performance loss in extreme environmental temperatures and thermal runaway (TR) is a major drawback of lithium-ion batteries (LIBs), raising significant concern. This study employed electrospinning to prepare flexible Al 2 SiO 5 nanofiber membranes for thermal insulation in batteries. These membranes exhibited low thermal conductivities of 0.03487, 0.03512, and 0.07384 W/(m•K) at −25, 25, and 800 °C, respectively, indicating that these membranes are excellent for thermal insulation. With the fiber membrane in place, the cell surface temperature changed slower toward ambient temperature than the control group. During charging and discharging at −25 °C, batteries wrapped with the fiber membrane exhibited a significantly higher capacity than the control group. In the case of thermal abuse, the battery module with fibers exhibited a 1608 s delay from the heating start to the TR onset compared to the battery module without membranes, and the time gap between safety valve rupture to TR onset was also 503 s more than the battery module without membranes. The fiber membranes have less effect on the surrounding cells than the control group, thus significantly improving battery safety.

The objective of this research was to develop a high-performance flexible silica aerogel composite for thermal insulation under high-temperature and thermal−force coupling conditions. Based on synthesis of flexible silica aerogels with methyltrimethoxysilane as the precursor, flexible silica aerogel composites were developed by wet-impregnating ceramic fiber felt. Morphology, microstructure, chemical structure, hydrophobicity, and compression performance evolutions of the flexible silica aerogels and their composite counterparts with temperature revealed that the resulting flexible silica aerogel samples have excellent stability at 900 °C. Flexible silica aerogel composites show 100 and 70% recovery with 50% strain after treatment at 500 and 900 °C, respectively. Thermal insulation performance of the flexible silica aerogel composites was comprehensively studied from different aspects, including thermal conductivity, thermal shield behavior under high-temperature and thermal−force coupling conditions, and thermal shock resistance. Thermal conductivities of the flexible silica aerogel composite at 25−1100 °C are lower than those of most reported aerogel composites. Coupling of force under high temperature leads to degradation of thermal insulation performance, owing to deformation with compression. The synthesis method of the flexible silica aerogel is facile and inspiring, and the flexible silica aerogel composites have promising prospects in thermal insulation under high-temperature and thermal-stress coupling conditions, such as suppressing thermal runaway propagation of lithium-ion batteries.
