Metal phase change energy storage

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 latent heat storage using alloys as phase change materials (PCMs)?

Scientific Reports 5, Article number: 9117 (2015) Cite this article Latent heat storage using alloys as phase change materials (PCMs) is an attractive option for high-temperature thermal energy storage. Encapsulation of these PCMs is essential for their successful use.

Can porous materials encapsulate liquid metal phase change materials?

Encapsulation of liquid metal phase change materials In the above research on the use of porous materials to enhance the thermal conductivity of LM, they can not only enhance the overall thermal conductivity of materials, but also play a certain role in packaging liquid PCMs. however, the leakage of LM cannot be completely avoided in this way.

What are liquid metal phase change materials (lmpcm)?

In addition to direct application in thermal management, liquid metal phase change materials (LMPCM) can be further enhanced with built-in fins [23, 24], carbon-based or metallic porous materials .

Do thermal storage materials have a trade-off between energy and power?

Researchers have developed figures of merit 12, 25, 26 to try to quantify the trade-off between the energy and power capabilities for thermal storage materials, and these figures of merit have been used to construct approximations of thermal Ragone plots 27.

Why is PCM used in energy storage & temperature regulation?

The PCM are efficient heat storage materials, which are accompanied by the storage and release of a large amount of thermal energy with little temperature change in the process of phase change. Therefore, it is widely used in the fields of energy storage and temperature regulation , , .
