Tailored phase change behavior of Na2SO4·10H2O/expanded graphite composite for thermal energy storage

Sodium sulfate decahydrate (SSD, Na2SO4·10H2O) is a suitable candidate for thermal storage applications as its high thermal latent heat and desirable phase change temperature, but it suffers from the supercooling, phase separation, and recalescence. In this paper, the SSD-CBO synthesized by SSD, carboxymethyl cellulose (CMC), borax decahydrate, and OP-10 successfully suppressed supercooling, and phase separation. Expanded graphite (EG) was used...
