What are solid-solid phase change materials (SS-PCMs) for thermal energy storage?

Solid-solid phase change materials (SS-PCMs) for thermal energy storage have received increasing interest because of their high energy-storage density and inherent advantages over solid-liquid counterparts (e.g., leakage free, no need for encapsulation, less phase segregation and smaller volume variation).

Are solid-to-solid phase transformations good for thermal energy storage?

A numerical analysis (using an experimentally validated numerical model) has revealed that some materials with solid-to-solid phase transformations offer an excellent capacity-power trade-off for thermal energy storage applications compared to the corresponding conventional phase change materials.

What is solid-state phase transformation in caloric materials?

Solid-state phase transformation in caloric materials is accompanied by significant changes in the degrees of freedom within a material, typically through a first-order transition between ordered (i.e., high-entropy) and less ordered (i.e., low-entropy) material phases.

What is a bottleneck in solid-solid phase change technology?

In the current development of solid-solid phase change technology, the main bottleneck that currently restricts is reflected in the relatively low latent heat and thermal conductivity of solid-solid PCMs.

Why do latent heat storage systems undergo solid-liquid phase transitions?

The most commonly used latent heat storage systems undergo solid-liquid phase transitions due to large heat storage density and small volume change between phases.

Are solid-liquid PCMs used in solar energy storage?

Solid-liquid PCMs are currently commonly used in applications, but their leakage and corrosiveness will affect the application of phase change materials in solar energy storage. Therefore, solid-solid PCMs have been widely used in practice .
