“…The cloud diagram indicates that the incorporation of glass fiber results in more concentrated PA liquefaction, which is beneficial for minimizing PA leakage. Compressive strength, which measures the capacity of materials to resist external forces within a specific range, is a crucial parameter for evaluating the mechanical properties of materials 26 . As depicted in Figure 10b, the compression simulation was performed to determine the structural deformation and bearing strength of the module with varying mass fractions.…”

Phase change materials (PCMs) have garnered significant interest in the field of passive cooling for lithium‐ion batteries in recent years due to their simple structure, low cost, and stable performance. This paper introduces a passive thermal management strategy based on nonuniform paraffin (PA) and glass fiber for battery modules. It explores the impact of glass fiber on the thermal conductivity and structural strength of PA, as well as the thermal management performance of the composite phase change battery module that combines the two materials. The findings reveal that the composite phase change module with a glass fiber mass fraction of 60%, operating at a discharge rate of 3C, maintains a temperature 0.76°C lower than that of the air‐cooling module. This reduction results in a decreased maximum temperature difference between the modules from 7.3 to 5.0°C and a decrease in the maximum temperature ratio from 16.9% to 11.6%. Moreover, compared to the PA phase change module, heat transfer to adjacent cells decreases by approximately 10% during thermal runaway, effectively suppressing thermal propagation. Additionally, the incorporation of glass fiber in this scheme enhances the compressive strength of the module by a factor of 9.81. This study presents a novel method to address the thermal management needs of batteries for heat dissipation and thermal insulation.

“…By comparison, it can be found that the infrared spectra of E7C3 composite phase change material is also the sum of PA, EG and CPEG, and there are no other functional group absorption peaks and obvious peak shifts, which further confirms that PA/EG/CPEG composite material is formed by physical adsorption, in which all components are chemically inert [28] and have good chemical compatibility. [29] In order to explore the thermal stability, TG analysis [30] was performed on PA, E10C0 and E7C3 phase change materials, respectively, and the results are shown in Figure 8a. It shows that PA exhibits a typical one-step decomposition reaction, [31] which starts at 150 °C and completes at 225 °C.…”

Paraffin (PA)/expanded graphite (EG) is an important composite phase change material with low cost, high heat storage, good thermal conductivity and cycling stability. Its thermal conductivity needs to be further improved for application in the thermal management system of power lithium‐ion batteries. In this paper, copper plated expanded graphite (CPEG) with 3D porous structure was prepared by electroless copper plating method, which was used as thermal conductivity enhancing material to replace part of EG in PA/EG composite materials. For the optimized phase change material composed of 80%PA‐14%EG‐6%CPEG, the copper content is very low (0.768 wt%), but its thermal conductivity can be significantly improved without loss of latent heat and thermal cycling stability. Its thermal conductivity is increased from 11 times to 16.5 times that of paraffin while compared with the copper‐free composite material (80%PA‐20%EG). The PA/EG/CPEG composite material exhibits good temperature control effect on power lithium‐ion batteries.

“…[21,22] EG is porous and their interlayer spaces can store PCMs. [17,[23][24][25][26][27] For example, M. Kenisarin et al introduced PW into two different EGs and revealed the optimal weight ratio of EG in PW/EG composites was 6 wt.%. [17] The maximum thermal conductivity of optimized PW/EG composites reached 1.26 W K À 1 m À 1 .…”

Structural Analysis of Phase Change Materials (PCMs)/Expanded Graphite (EG) Composites and Their Thermal Behavior under Hot and Humid Conditions

Expanded graphite (EG) has been used to store phase change materials (PCM) to enhance thermal conductivity and avoid leakage. However, systematic investigation on physical structure of various embedded PCMs in EG is not reported. Besides, the effect of environment on thermal behavior of PCM/EG composites has not been investigated yet. In this work, three common PCMs (including myristic acid (MA), polyethylene glycol (PEG) and paraffin wax (PW)) were embedded in EG and three PCM/EG composites were obtained. As a result, capillary force between EG and PCMs supported encapsulation of PCMs in EG. PCM/EG composites had narrower phase change range while supercooling degree values were different when various PCMs were used. Besides, the hot and humid environment had a side effect on thermal energy storage of PCMs and PCM/EG composites. The inherent hydrophilicity of PCMs was essential for resistance against side effect of moisture on thermal energy storage.
