Phase change materials (PCMs) having a large latent heat during solid-liquid phase transition are promising for thermal energy storage applications. However, the relatively low thermal conductivity of the majority of promising PCMs (<10 W/ (m ⋅ K)) limits the power density and overall storage efficiency.
Conductive filler with reduced volume in phase change composites is a viable solution for improving the thermal performance and energy density of PCMs. A form-stable PCM (FSPCM) is a composite material that contains solid–liquid PCM for thermal energy storage and a supporting material to maintain the solid shape of the FSPCM.
The strategies for tuning the thermal conductivity of PCMs and their potential energy applications, such as thermal energy harvesting and storage, thermal management of batteries, thermal diodes, and other forms of energy utilization, are summarized systematically.
To bring the phase change heat storage solution into a broader market, more intensive studies in fields of phonon thermal conductivity mechanism, development of high performance composite PCMs and efficient and compact phase change heat storage system are still required. The authors declare no competing financial interest.
This review provides the useful insights about recent advances in the field of PCMs. The phase change slurries can effectively improve the thermal performance of photovoltaic/thermal systems. The thermal conductivity of PCMs can be enhanced significantly by PCM slurries, MOFs, exfoliated graphite nanoplatelets and composite PCMs.
