The encapsulation of phase change materials (PCMs) into additive manufactured porous supports is attracting great interest for developing thermal energy storage (TES) with improved performance. Here, highly (86 %) self-supported 3D activated carbon/alumina are fabricated by direct ink writing (DIW) and, then, infiltrated solar salt, a corrosive PCM melting temperature around 220 °C commonly employed in concentrated power plants. This novel, robust, chemically compatible, and lightweight 3DTES exhibits good efficiency (70 stability, high density (381 J g−1), avoids the liquid leakage molten salt. Besides, support promotes better ability to absorb (79 enhances conductivity salt (up 64 %). These results validate use DIW manufacturing innovative TES an enhanced behaviour.

Flexible and recyclable thermally conductive phase change composites with shape stability

Journal of Applied Polymer Science, Journal Year: 2024, Volume and Issue: 141(38)

Published: July 3, 2024

Abstract Form‐stable and flexible highly thermally conductive phase change composites are crucial for thermal management. In this work, based on the associative exchangeable crosslinkers derived from reaction of epoxidized soybean oil (ESO) sebacic acid (SA), a kind recyclable composite with shape stability is prepared. The stabilization achieved through co‐cooperation expanded graphite (EG) dynamic covalent crosslinking network. conductivity enhanced by embedding boron nitride (BN). When mass fraction BN 25%, can reach 4.03 W/(m·K). results indicate that prepared PCMs have excellent flexibility form stability, suggesting potential application in management electronic devices. presence bonds makes matrix degradable under mild conditions, enabling recycling valuable fillers, which proves to be sustainable. This work introduces novel method preparing vitrimer.

Heliyon, Journal Year: 2024, Volume and Issue: 10(13), P. e33992 - e33992

Published: July 1, 2024

This study explores the potential of untapped lithium hydroxide (LiOH) as a phase change material for thermal energy storage. By overcoming challenges associated with liquid LiOH leakage, we successfully thermal-cycled in laboratory scale experimentation, and observed its stability (>500 cycles), without chemical decomposition. step has never been performed to date. Its solid-to-liquid reversible transitions temperatures related solidification/melting enthalpies values have verified. Then, first experimental characterization LiOH's properties shows unexpected heat capacity, conductivity diffusivity, contradiction few ones available literature. opens avenues applications storage sensible latent heat, shown through increased cycle efficiency system if based on capacity; up six times more volumetric density compared traditional Solar Salt-based systems used solar tower plant (4.5 GJ/m3 vs. 0.76 over 1000 cycles). Additionally, softening phenomenon that occurs inconsistently during heating, but which may account excellent melting interplay other raw chemicals. new insight contributes certainly underlying mechanisms synthesis another promising development: peritectic compound Li4Br(OH)3. pioneering work suggests ultra-compact filling intermediary gap from current next-generation power plants, although large-scale application requires further investigation achieve economic viability.
