Metallic 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.

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 metallic phase change materials?

Metallic phase change materials offer an approach to rapidly transport heat away from a critical device or component, thereby buffering the temperature of that device during periods of transient high power operation. These compounds are of increasing interest to both electronics packaging thermal management and solar thermal communities.

Are metallic alloys a phase change material for heat storage?

In Novel Metallic Alloys as Phase Change Materials for Heat Storage in Direct Steam Generation Applications, AIP Conference Proceedings, AIP Publishing: 2016; p 050032. [Pr 90] Preston-Thomas, H., The International Temperature Scale of 1990 (Its-90). Metrologia 1990, 27, 3.

What is a phase transition in thermal energy storage?

In the context of thermal energy storage materials, the phase transition is generally a transition between two condensed phases (e.g., liquid-solid, or solid-solid), allowing heat to be absorbed and released over many cycles, with minimal change in volume each cycle.
