Comparison of composite phase change energy storage materials

Are phase change materials suitable for thermal energy storage?

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.

Are composite phase change materials suitable for energy management?

Therefore, designing and developing composite phase change materials (CPCMs) with both high thermal conductivity and good shape stability remain a major challenge in the field of energy management.

What is phase change material (PCM) based thermal energy storage?

Bayon, A. ∙ Bader, R. ∙ Jafarian, M. 86. Phase change material (PCM)-based thermal energy storage significantly affects emerging applications, with recent advancements in enhancing heat capacity and cooling power.

What are the advantages of composite phase change material (CPCM)?

High enthalpy and high thermal conductivity are suitable for solar systems. Composite phase change material (CPCM) with the advantages of high enthalpy and constant temperature phase change, has been widely used in many fields, such as photovoltaic thermal system, building envelope structure and so on.

Do open-cellular metal foams improve thermal conductivity of phase change materials?

Due to their high thermal conductivity, open-cellular metal foams are frequently used to improve the thermal conductivity of phase change materials. In this paper, the effective thermal conductivity of open-cellular foam filled with PCM with cubic units containing 12 solid tubular ribs was determined using an effective medium theory for composites.

Are MOF-based composite PCMS suitable for thermal energy storage?

MOFs are attractive supporting materials for the encapsulation of PCMs due to their unique merits (ultrahigh active surface area, ultrahigh porosity, tunable pore size, and controllable functional group species). Here, we summarize the recent advances in MOF-based composite PCMs for thermal energy storage.
