Are phase change materials suitable for thermal energy storage?

Phase change materials are promising for thermal energy storage yet their practical potential is challenging to assess. Here, using an analogy with batteries, Woods et al. use the thermal rate capability and Ragone plots to evaluate trade-offs in energy storage density and power density in thermal storage devices.

Why is phase change energy storage a non-stationary process?

During the phase change process, the temperature of PCM remains stable, while the liquid phase rate will change continuously, which implies that phase change energy storage is a non-stationary process. Additionally, the heat storage/release of the phase change energy storage process proceeds in a very short time.

Which phase change material is best for battery thermal management?

Phase change materials for thermal management and energy storage: a review Polymer/expanded graphite-based flexible phase change material with high thermal conductivity for battery thermal management Z.-F. Zhou, X.-W. Lin, R.-J. Ji, D.-Q. Zhu, B. Chen, H. Wang, et al.

What determines the value of a phase change material?

The value of a phase change material is defined by its energy and power density—the total available storage capacity and the speed at which it can be accessed. These are influenced by material properties but cannot be defined with these properties alone.

Are phase change materials suitable for heating & cooling applications?

The research, design, and development (RD&D) for phase change materials have attracted great interest for both heating and cooling applications due to their considerable environmental-friendly nature and capability of storing a large amount of thermal energy in small volumes as widely studied through experiments [7, 8].

Is Cascade phase change energy storage a viable solution?

From the perspective of the system, cascade phase change energy storage (CPCES) technology provides a promising solution. Numerous studies have thoroughly investigated the critical parameters of the energy storage process in the CPCES system, but there is still a lack of relevant discussion on the current status and bottlenecks of this technology.
