“…Phase change energy storage is an effective way to solve energy and environmental problems. [81][82][83][84][85][86][87][88][89][90][91][92][93][94] However, there are still many problems that need to be resolved during the development of PCMs. For example, PCMs that use melamine resin and urea-formaldehyde resin as wall materials will release more or less free formaldehyde during the usage, which endangers human health.…”

Phase change materials (PCMs) store and release energy in the phase change processes. In recent years, PCMs have gained increasing attention due to their excellent properties such as high latent heat storage capacity, appropriate solid-liquid phase change temperature, thermal reliability, and low cost. Herein, classification, characteristics, and evaluation criteria of organic/composite PCMs are systematically illustrated, and some typical preparation methods are introduced, such as in-situ polymerization, interfacial polymerization, spray drying method, porous materials adsorption method, sol-gel method, meltimpregnated and mixing method, electrospinning method, vacuum infiltration and ultrasonic method are introduced. In addition, this review presents some applications of PCMs in the utilization of solar energy, building materials, air conditioning, industrial waste heat recovery, and military camouflage and stealth. Finally, the development tendency of PCMs is discussed.

“…Compared with traditional CPCM, the flexible CPCM effectively reduced the temperature rise of the battery pack. A thermally induced flexible CPCM composing of paraffin, olefin block copolymer, and EG was prepared by Wu et al [ 53,54 ] When the flexible CPCM was heated up 60 °C for a period, it was transformed into flexible material and the battery could be inserted into the hole. When the temperature returned to 25 °C, the flexible CPCM transferred into rigid material again to finish assemble, and the battery was fixed by interference fit.…”

With the rapid development of electric vehicles (EVs), thermal safety issues have become increasingly prominent. In the charging and discharging process, a proper battery thermal management system (BTMS) can control the temperature of the power battery pack, which is essential to ensure the performance and safety of EVs. Among various cooling technologies, phase change material (PCM) cooling is widely used in BTMS due to its excellent characteristics, such as simple structure, good cooling effect, and no extra energy consumption. Herein, the research progress of PCM on BTMS is reviewed, including the overview of PCMs, the studies of single PCM‐based BTMS, and the development of hybrid PCM‐based BTMS. The results have found that the cooling performance of PCM‐based BTMS is determined by excellent PCM properties and suitable BTMS structure. In addition, the fin‐enhanced structure and active phase change slurry (PCS) can effectively improve the reliability and flexibility of BTMS applications. The hybrid BTMS consisting of PCM and other cooling technology can promote the heat dissipation of PCM, which helps to solve PCM heat saturation and further reduce the battery temperature. Finally, insufficient studies in current research are pointed out, and a future development direction is also reported.

“…Hence, they can be used to manage natural energy resources more efficiently and can be exploited to temporarily store excess heat in solar-thermal power plants or solar-thermal systems for indoor temperature regulation and water heating [ 4 , 5 , 6 ]. PCMs have also been used for thermal management in buildings, smart textiles, electronic components, and electric vehicle batteries [ 7 , 8 , 9 , 10 ], as they can maintain the temperature in a controlled range during phase change. The most diffused PCMs working at low-medium temperature (0–120 °C) are organic solid–liquid oligomers such as paraffins, poly(ethylene glycol)s (PEGs), and fatty acids and alcohols.…”

Epoxy/hollow glass microsphere (HGM) syntactic foams (SFs) are peculiar materials developed to combine low density, low thermal conductivity, and elevated mechanical properties. In this work, multifunctional SFs endowed with both structural and thermal management properties were produced for the first time, by combining an epoxy matrix with HGM and a microencapsulated phase change material (PCM) having a melting temperature of 43 °C. Systems with a total filler content (HGM + PCM) up to 40 vol% were prepared and characterized from the mechanical point of view with a broad experimental campaign comprising quasi-static, impact, and fracture toughness tests. The experimental results were statistically treated and fitted with a linear model, to produce ternary phase diagrams to provide a comprehensive interpretation of the mechanical behaviour of the prepared foams. In quasi-static tests, HGM introduction helps to retain the specific tensile elastic modulus and to increase the specific compressive modulus. The brittle nature of HGMs decreases the Charpy impact properties of the SFs, while the PCM insertion improve their toughness. This result is confirmed in KIC and GIC tests, where the composition with 20 vol% of PCM shows an increase of 80% and 370% in KIC and GIC in to neat epoxy, respectively. The most promising compositions are those combining PCM and HGMs with a total particle volume fraction up to 40 vol%, thanks to their optimal combination of thermal management capability, lightness, thermal insulation, and mechanical properties. The ability to fine-tune the properties of the SFs, together with the acquired thermal energy storage (TES) capability, confirm the great potential of these multifunctional materials in automotive, electronics, and aerospace industries.
