“…Besides, the nature of porous materials will be assigned to the associated composites, such as high thermal conductivity, highly flame retardancy, etc. In addition to the building [12] and solar-thermal [13] fields which composite PCMs is commonly used, the guest-host interaction between the porous skeleton and PCM makes composites applicable to more other fields, including magnetic-thermal conversion [14] , thermal management of electronics [15] , medical [16] and etc. .…”

“…Another REV model for PCM/carbon foam considered the thermodynamic equilibrium was proposed by Alshaer et al where the PCM's thermal conductivity was enhanced by inserting nano carbon tube. The three‐dimensional numerical model for cylindrical battery using PCM/porous‐graphite‐matrix was developed by Greco et al, Nada, and Alshaer . In another numerical model, the composite PCM was treated as the single material, and the thermal properties such as thermal conductivity, latent heat, and density were directly applied in other studies to simulate the phase change process.…”

Summary With the latent heat, the phase change material (PCM) is widely used in battery thermal management (BTM) to control the temperature. In this paper, the porous medium is employed to enhance the heat transfer of PCM. The lattice Boltzmann model for PCM/porous medium in pore scale is considered, where the mesh system with porous medium (fixed point) is generated by quartet structure generation set (QSGS) method. The effects of the Rayleigh number and porosity on the heat transfer process in BTM are investigated. The results show that decreasing the porosity will accelerate the melting rate. When the porosities are 0.9, 0.8, 0.7, and 0.6, the total melting times are decreased by 23.7%, 43.3%, 58.0%, and 75.4%, compared with pure PCM. The heat is transferred through the high‐conductivity framework. The natural convection in the porous medium is weak, and the conduction is the dominated heat transfer. As a result, the area of solid–liquid interface will be increased, and the heat‐transferred rate is accelerated. However, when the Rayleigh number is raised to 105, applying the porous medium with porosity of 0.9 will increase the total melting time, resulted from the stronger natural convection of PCM. The present study is helpful for design of PCM/porous medium‐based BTM.

“…Thus, CFms are actively investigated as heat sink materials because of their good properties, such as high thermal stability, high thermal/electrical conductivity, low density, high porosity and high specific surface area [4,5]. CFms are suitable materials for applications in phase-change materials, such as in latent heat thermal energy storage and lithium-ion batteries [6][7][8][9].CFms are prepared from thermoplastic graphitizable precursors, such as petroleum-derived, coal-derived and mesophase pitch (MP). In particular, MP has been widely used as an appropriate precursor for high-performance carbon materials due to its attractive properties, i.e., high coke yield, low softening point, and high fluidity [10].…”

Carbon foams (CFms) are of crucial importance in electrical and mechanical devices due to their high thermal conductivity used for eliminating high heat flow and maintaining low temperatures [1]. The most common CFms are types of aluminum alloys, copper and diamond. However, the mechanical properties of metal-based heat sink materials are difficult to control at temperatures over 550°C [2,3]. Thus, CFms are actively investigated as heat sink materials because of their good properties, such as high thermal stability, high thermal/electrical conductivity, low density, high porosity and high specific surface area [4,5]. CFms are suitable materials for applications in phase-change materials, such as in latent heat thermal energy storage and lithium-ion batteries [6][7][8][9].CFms are prepared from thermoplastic graphitizable precursors, such as petroleum-derived, coal-derived and mesophase pitch (MP). In particular, MP has been widely used as an appropriate precursor for high-performance carbon materials due to its attractive properties, i.e., high coke yield, low softening point, and high fluidity [10]. Previous processes used a blowing technique, or pressure release, to produce foam from MP. These manufacturing techniques have many disadvantages: the volume fraction of generated cells cannot be precisely controlled, and controlling the shape and distribution of cells is difficult, if not impossible [11]. To better control and tailor the structure of such foams, polymer template methods are actively being researched. Hydrogel template methods are suitable for preparing high-strength CFms due to their large quantities of carbon precursors and the pressure generated through hydrogel shrinkage via heat treatment [10,12]. However, their mechanical strengths are low because of their high porosities.One method for improving the mechanical strength of CFms is adding fillers with a high mechanical strength. Several additives have been used as fillers, including carbon nanofibers, short carbon fibers, graphite and graphene nanosheets [13][14][15][16][17][18][19][20][21][22]. In particular, graphite has beneficial properties that include high lubricating ability, heat resistance, corrosion resistance and thermal/electrical conductivity. It has been widely applied in various fields as a highly functional component with efficient properties. Additionally, the theoretical thermal conductivity of graphite is high, with values ranging from 3000 to 5000 W/mK, and its mechanical strength is 1100 GPa [23,24]. The thermal/mechanical properties of CFms could be improved by the addition of carbon nanofillers with good thermal/mechanical properties through the formation of network structures comprising CFms and carbon nanofillers. Furthermore, carbon nanofillers can be carbon-coated (C-coated) to improve the interfacial bonding with metal. For example, Katzman [25] showed that carbon fibers could be C-coated using amorphous pitch to improve the interfacial bonding with metal oxide and prepare a carbon-fiber-reinforced metal-matrix compo...
