Manufacturing of Continuous Core–Shell Hydrated Salt Fibers for Room Temperature Thermal Energy Storage

Abstract

Room Temperature Thermal Energy Storage

In article number 2400012, Michael D. Toomey, Jaswinder Sharma, and co-workers demonstrate the first example of wet-spun PCM fibers comprised of a polymer sheath and a salt hydrate core for thermal energy storage applications. Fibers produced using this scalable production method achieve enthalpies of melting of ca. 130 J/g, melting onset at 29°C, and supercooling of 4.8°C while retaining 96.5% of its phase change capacity after 1000 cycles.
