“…Liu et al 21 reviewed PCMs with high-melting temperature over 300 C for concentrated solar thermal power plants, as well as approaches for improving their thermal performance. Costa and Kenisarin 22 provided a review article about the thermophysical properties of metallic PCM for low-, medium-, and high-melting temperatures, including their mathematical theoretical predictions. Liu et al 23 conducted a review for high-melting temperature of inorganic salt mixtures and metal alloys in the range of 500 C until 700 C. Mili an et al 24 summarized the encapsulation PCM methods for a wide range melting temperature.…”

Summary Microencapsulated phase change materials (MEPCMs) have made tremendous advancements in recent years, owing to their increased demand for a variety of energy storage applications. In this paper, current microencapsulation techniques, enhancement, and use of medium‐ and high‐melting phase change materials (PCMs) are reviewed, as well as their potential benefits and limitations. The most frequently employed PCMs for medium‐ and high‐temperature applications were recognized as salt‐based, metallic, inorganic compound, and eutectic. Meanwhile, polymethyl methacrylate (PMMA), polystyrene‐butylacrylate (PSBA), polyethyl‐2‐cyanoacrylate (PECA), and polyurethane were widely used as polymer shell materials for encapsulating medium‐ and high‐melting point PCMs via chemical method, whereas inorganic silica shell was synthesized via various techniques. Hydrolysis followed by heat‐oxidation treatment has been extensively studied since 2015 to encapsulate either metal or alloy within Al2O3 shells. Different techniques were developed to generate void between core and shell material to accommodate volume expansion during phase transition. Numerous approaches, including the incorporation of metal particles, carbon, and ceramic, have been found as ways to enhance the thermal performance of PCMs. Multiple storage arrangements were also established to be an effective way of enhancing the overall efficiency of medium‐high melting PCM storage systems. Finally, the paper highlights the potential of medium‐ and high‐melting temperature PCMs for solar power generation, solar cooking, and industrial waste heat recovering applications.

“…1,2 Metal PCMs have attracted much attention in recent years, due to their outstanding advantages in high thermal conductivity, high latent heat per unit volume and small volume change before and aer phase change. 2,3 In particular, the value of low melting point metal or so called "liquid metal" represented by gallium in passive thermal management has long been reported, 4,5 and some recent studies also demonstrated its potential in thermoregulation and aerospace. 6,7 The advantages and disadvantages of the above PCMs are very clear.…”

“…9 These PCMs are best for storing thermal energy in the low-temperature range (below 120 C). Inorganic PCMs, on the other hand, include salt hydrates 10 (generally used for low temperature applications), nitrates, 11 carbonates 12 (for medium temperature applications, that is, below 300 C); chlorides 13 and metals 14 (suitable for high temperature applications). Of all inorganic PCM materials, nitrate salts show desirable properties such as higher storage density per unit volume, adequate thermal conductivity and more stability, causing them to be chosen as potential candidates.…”

Summary Using a thermogravimetric analyzer, the thermal stability of pure eutectic phase change material (PEPCM) (LiNO3 + NaCl) and composite eutectic PCM (CEPCM) mixture (ie, PCM containing 9% expanded graphite [EG]) was examined. PEPCM and CEPCM degradation kinetics were studied using model free kinetics methods. The activation energy of both PCM samples was evaluated using the Kissinger‐Akahira‐Sunose (KAS), Flynn‐Wall‐Ozawa (FWO), Starink, Friedman and Vyazovkin kinetic models. The calculated activation energies for Vyazovkin, Frideman, Ozawa, KAS and Starink techniques for PEPCM were 80.62‐149.2, 108.1‐180.18, 83.74‐136.17, 73.55‐127.02 and 74.64‐149.9 kJ/mol, respectively. Likewise, the activation energy of CEPCM vary between 59.4‐161.41, 83.97‐188.69, 57.1‐147.32, 54.19‐137.43 and 55‐160.65 kJ/mol. Hybrid neural networks such as ANN‐PSO and ANFIS were used to model the degradation of PCM samples. The type of PCM, the heating rate, and the temperature were applied as input parameters, while the sample's mass loss was utilized as an output parameter. The created hybrid models are capable of effectively predicting experimental TGA data.
