Miscibility gap alloys with a ceramic matrix for thermal energy storage

A review of metallic materials for latent heat thermal energy storage: Thermophysical properties, applications, and challenges

“…In the last years, much of the research efforts in phase change materials have mainly focused on the characterization of thermophysical properties of organic and salt hydrate; for metallic materials, the data found in the literature is incomplete and discrepant [46,47]. Recently, new promising utilizations of metals and alloys for thermal energy storage has appeared in different research areas: miscibility gap alloys [48][49][50][51][52][53][54][55][56], metal-organic framework and shape-stabilized PCMs [57][58][59][60][61], encapulation [62][63][64][65][66][67][68][69].The present work aims to provide an extensive and detailed compilation and analysis of the thermophysical properties of metals and alloys as phase change materials. The information presented includes the fundamental thermophysical properties, the temperature dependence of critical properties from the engineering design point of view, a summary of potential applications, and the main challenges of metallic PCMs.…”
