“…Adding FSPCM to the battery module can not only improve the performance of the battery, but also ensure the safety and reliability of the battery during using process. Huang et al 118 obtained flexible FSPCM with flame retardant properties by adding flame retardants to paraffin/styrene‐butadiene‐styrene/EG. A heating rod at 200°C is used to simulate the thermal runaway of the battery in the experiment.…”

Phase change materials possess the merits of high latent heat and a small range of phase change temperature variation. Therefore, there are great prospects for applying in heat energy storage and thermal management. However, the commonly used solid‐liquid phase change materials are prone to leakage as the phase change process occurs. To address this drawback of solid‐liquid phase change materials, researchers have developed form‐stable phase change materials. There are three main strategies for preparation of form‐stable phase change materials. The objectives of this article are: (1) The form‐stable phase change materials are classified according to the preparation strategy, and the properties of each class of form‐stable phase change materials are presented. (2) The advantages and disadvantages of form‐stable phase change materials are also discussed. (3) It is also summarized that the methods to improve the drawbacks and enhance the characteristics of form‐stable phase change materials. (4) Moreover, the multifunctional form‐stable phase change materials are also described. (5) Finally, applications of form‐stable phase change materials are analyzed and discussed.

This study addresses the thermal safety issues of ternary lithium-ion batteries, focusing on NCM523 monomer lithium-ion batteries as the research subject. A thermal abuse model for lithium-ion batteries is established, and thermal Oven experiments are simulated to investigate the thermal runaway (TR) process of lithium-ion batteries under high-temperature conditions (135°C ~ 195°C). The study analyzes the impact of various factors such as environmental temperature, state of charge (SOC) of the battery, initial battery temperature, and heat transfer coefficient on the thermal runaway of lithium-ion batteries. Additionally, it examines the changes in the internal material content of the battery and heat generation in various parts of the battery during the thermal runaway process. The research reveals that at an oven temperature of 195°C, the maximum temperature during the thermal runaway of lithium-ion batteries can reach approximately 625°C. The reactions between the negative electrode and electrolyte, as well as the positive electrode and electrolyte, are the primary sources of heat generation during thermal runaway. An increase in the state of charge of the battery leads to an earlier onset of thermal runaway. Furthermore, an increase in the heat transfer coefficient results in an earlier onset of thermal runaway. Implementing appropriate cooling methods (liquid cooling or direct cooling) can to some extent prevent the occurrence of thermal runaway phenomena.

“…During 3C discharge, the maximum temperature of the battery was 14.6 • C lower than that of natural cooling. Furthermore, a flexible PCM composed of styrene-butadiene-styrene (SBS), paraffin, and aluminum nitride (AlN) was utilized for BTMS [48]. At 2C discharge, the surface temperature of the battery decreased by 5.8 • C compared to natural air cooling, while at 3C discharge, the temperature dropped by 6.5 • C. By conducting experimental analysis, RPCM1 and RPCM2 have the best cooling effect.…”

Composite phase change materials commonly exhibit drawbacks, such as low thermal conductivity, flammability, and potential leakage. This study focuses on the development of a novel flame-retardant phase change material (RPCM). The material’s characteristics and its application in the thermal management of lithium-ion batteries are investigated. Polyethylene glycol (PEG) serves as the medium for phase change; expanded graphite (EG) and multi-walled carbon nanotubes (MWCNT) are incorporated. Moreover, an intumescent flame retardant (IFR) system based on ammonium polyphosphate (APP) is constructed, aided by the inclusion of bio-based flame-retardant chitosan (CS) and barium phytate (PA-Ba), which can improve the flame retardancy of the material. Experimental results demonstrate that the RPCM, containing 15% IFR content, exhibits outstanding flame retardancy, achieving a V-0 flame retardant rating in vertical combustion tests. Moreover, the material exhibits excellent thermomechanical properties and thermal stability. Notably, the material’s thermal conductivity is 558% higher than that of pure PEG. After 2C and 3C high-rate discharge cycles, the highest temperature reached by the battery module cooled with RPCM is 18.71 °C lower than that of natural air-cooling; the material significantly reduces the temperature difference within the module by 62.7%, which achieves efficient and safe thermal management.
