“…During DSC analysis, the amount of energy absorbed or released upon heating or cooling is measured providing qualitative and quantitative data during endothermic (heat absorption) and exothermic (heat rejection) phase transitions. In DSC analysis, the change of heat flux is recorded with respect to time; however, the heating rate and sample mass is most important because the changing heat rate and sample mass will give temperature‐heat flow responses …”

“…Therefore, EPCMs have been gaining the promising attention in recent years to absorb solar thermal energy in the form of latent heat and release it later on to meet the energy demands. The utilisation of micro‐ and nano‐PCMs has been under investigation for photo‐thermal conversion, solar cells, direct absorb solar collector, photo catalyst, storage tank or container, heat exchanger, and minichannel to harvest and convert solar energy directly and indirectly . Zeng et al synthesised the core‐shell nanoparticles using Sn/SiO 2 /Ag, where Sn was used as the core material to store the thermal energy, SiO 2 was used as a shell material to provide containment, and Ag shell was used to enhance the light absorption intensity.…”

Summary With advancement in technology—nanotechnology, various thermal energy storage (TES) materials have been invented and modified with promising thermal transport properties. Solid‐liquid phase change materials (PCMs) have been extensively used as TES materials for various energy applications due to their highly favourable thermal properties. The class of PCMs, organic phase change materials (OPCMs), has more potential and advantages over inorganic phase change materials (IPCMs), having high phase change enthalpy. However, OPCMs possess low thermal conductivity as well as density and suffer leakage during the melting phase. The encapsulation technologies (ie, micro and nano) of PCMs, with organic and inorganic materials, have a tendency to enhance the thermal conductivity, effective heat transfer, and leakage issues as TES materials. The encapsulation of PCMs involves several technologies to develop at both micro and nano levels, called micro‐encapsulated PCMs (micro‐PCM) and nano‐encapsulated PCMs (nano‐PCM), respectively. This study covers a wide range of preparation methods, thermal and morphological characteristics, stability, applications, and future perspective of micro‐/nano‐PCMs as TES materials. The potential applications, such as solar‐to‐thermal and electrical‐to‐thermal conversions, thermal management, building, textile, foam, medical industry of micro‐ and nano‐PCMs, are reviewed critically. Finally, this review paper highlights the emerging future research paths of micro‐/nano‐PCMs for thermal energy storage.

“…Moreover, the wettability with molten salts is good, and they can support temperatures above 1000 • C. However, they have low values of thermal conductivity (<0.15 W/m/K), and the melting infiltration route is needed for ss-composite preparation, which is more expensive than the cold compression method.

Li4(OH)3Br-Based Shape Stabilized Composites for High-Temperature TES Applications: Selection of the Most Convenient Supporting Material

et al. 2021

Peritectic compound Li4(OH)3Br has been recently proposed as phase change material (PCM) for thermal energy storage (TES) applications at approx. 300 °C Compared to competitor PCM materials (e.g., sodium nitrate), the main assets of this compound are high volumetric latent heat storage capacity (>140 kWh/m3) and very low volume changes (<3%) during peritectic reaction and melting. The objective of the present work was to find proper supporting materials able to shape stabilize Li4(OH)3Br during the formation of the melt and after its complete melting, avoiding any leakage and thus obtaining a composite apparently always in the solid state during the charge and discharge of the TES material. Micro-nanoparticles of MgO, Fe2O3, CuO, SiO2 and Al2O3 have been considered as candidate supporting materials combined with the cold-compression route for shape-stabilized composites preparation. The work carried out allowed for the identification of the most promising composite based on MgO nanoparticles through a deep experimental analysis and characterization, including chemical compatibility tests, anti-leakage performance evaluation, structural and thermodynamic properties analysis and preliminary cycling stability study.

Porous ceramics with high open porosity and good mechanical properties were successfully prepared from fly ash rich in CaO. An addition of 30–50wt.% dolomite decreased the average pore diameter from ∼11.79 μm to ∼2.82μm due to the decrease of viscosity with high dolomite addition, while there is an increase in open porosity from 48.63% to 53.23%. SEM results suggested that pores were firstly surrounded by glassy phase. With the addition of more than 30 wt.% of dolomite, pores were covered by loose structure. XRD results showed the changes in crystal phases of sintered ceramics, from anorthite sodian to alkaline basalt and then to calcium magnesium silicate. CaO and MgO from decomposed dolomite were proposed to be the main reason on modification closed pores to open ones. Except this, CO2 emission and crystalline water emission during sintering were also contributed to the formation of open pores in porous ceramics.
