“…Thermal storage capacity ( R ) and the effectiveness of latent heat storage ( E ) are the two decisive thermal performance indicators for thermal storage by ss-PCMs [ 27 ], which are related to the enthalpy of melting and crystallization of ss-PCMs. The enthalpies of melting (Δ H m ) and crystallization (Δ H c ) can be determined by calculating the integral area of the peaks in DSC curves.…”

Aiming to promote the application of D-mannitol in the field of phase change thermal storage, obstacles, including low thermal storage efficiency and high supercooling, should be properly disposed of. The adoption of adaptable and low-cost supporting materials to make shape-stable phase change materials (ss-PCMs) affordable is a primary solution to solve the above shortcomings. In this study, high-performance ss-PCM for effective medium-temperature heat storage was prepared using expanded vermiculite as the support for D-mannitol preservation. Among the three candidates that treated the raw vermiculite by dilute acid, calcination, and microwave heating, the calcinated expanded vermiculite (CV) was characterized as the most suitable one. After impregnating D-mannitol into the CV carrier by vacuum, a melting enthalpy of 205.1 J/g and a crystallization enthalpy of 174.1 J/g were achieved by the as-received CV/D-mannitol ss-PCM. Additionally, the supercooling of the ss-PCM was reduced to 45.6 °C. The novel CV/D-mannitol ss-PCM also exhibited excellent reusability and stability. All the findings indicate that the abundant and inexpensive CV exhibited great potential as the supporting material for D-mannitol-based ss-PCMs, which allow effective waste heat recovery and temperature regulation.

With the sharp increase in modern energy consumption, phase change composites with the characteristics of rapid preparation are employed for thermal energy storage to meet the challenge of energy crisis. In this study, a NaCl-assisted carbonization process was used to construct porous Pleurotus eryngii carbon with ultra-low volume shrinkage rate of 2%, which providing enormous space for encapsulation of phase change materials. Such composite possesses exceptional thermal stability, with an absorption rate of 88.24%, a melting enthalpy of 174.87 J/g, and a relative enthalpy efficiency of 97.78%. Consequently, the resultant composites exhibit outstanding performances in storing and releasing thermal energy for photo-thermal, electric-thermal and magnetic-thermal conversion. This study presents a highly valuable strategy into the quick fabrication of phase change composites, facilitating their practical applications in thermal energy storage.
