Preparation and characterization of a shape-stable xylitol/expanded graphite composite phase change material for thermal energy storage

Experimental study of metal‐oxide nanoparticles on the thermal properties of erythritol for thermal energy storage

“…For latent heat of NePCMs, the phase transition temperature of nanoparticles was much higher than erythritol, which indicated that no phase transition occurred for nanoparticles during the DSC test. Therefore, in contrast with pure erythritol, the heat of fusion and solidification of NePCMs added with nanoparticles were reduced proportionally 14,52 . The experimental results from DSC curves were similar to the theoretical results.…”

“…LHS has many advantages in energy density and technological maturity that are not available in sensible heat storage and thermochemical storage. 14 LHS can realize heat storage and release almost without temperature variation, whose gravimetric energy density is 2-4 times 12 higher than sensible heat storage. 15 Besides, LHS has a smaller volume of the TES system and less heat loss during the process of heat storage.…”

Fabrication of Biobased Advanced Phase Change Material and Multifunctional Composites for Efficient Thermal Management

“…With the rapidly developing next-generation technologies, such as 5G communication, wide-band-gap (WBG) semiconductors, electric vehicles, energy storage systems, and solar cells, building efficient thermal management systems in electric devices has become critical. − Specifically, the severe thermal accumulation in electric vehicles is a significant challenge. , Moreover, owing to the increasing focus on eco-friendly policies, biobased materials have attracted significant attention. , Phase change materials (PCMs) such as paraffin, stearic acid, and palmitic acid can store and release large amounts of heat energy during the phase change from the solid state to the liquid state, which makes PCMs efficient thermal management materials. , However, flammability, which could lead to potential fire risks during the application of PCM composites, is the critical drawback hindering the organics from wide applications. , Sugar alcohols such as erythritol, xylitol, and mannitol are representative biobased PCMs, and their multiple hydroxyl groups induce a high level of latent heat through hydrogen interaction, which is the most important property of PCMs. Especially, erythritol has been widely used in food, medicine, chemical industry, and other fields due to its low hygroscopicity, high latent heat (390 J/g), and thermal stability.…”
