Pcm energy storage materials

What is PCM thermal storage?

PCMs have extensive application potential, including the passive thermal management of electronics, battery protection, short- and long-term energy storage, and energy conversion. In this work, we presented a comprehensive overview of PCM thermal storage at the multi-physics fundamental level, materials level, device level, and systems level.

Can PCMS be used for thermal energy storage?

The FT-IR analysis revealed that there was no change in the chemical structure after thermal cycles and they proposed that these PCMs can be the potential candidates for storage of thermal energy with long term reliability and stability.

How to determine thermal properties of a PCM?

There are several technical methods, which have been developed to determine the thermal properties such as latent heat storage, the temperature during change of phase, and specific heat of an energy storage material. The most commonly used techniques for thermal analysis of PCMs are the T-history method and DSC (differential scanning calorimetry).

Can composite PCM be used for thermal energy storage?

Meanwhile, X-ray diffraction showed that the crystal structure of CaCl 2 ·6H 2 O is sustained in the porous structure of sepiolite which prevented the reduction of supercooling of composite PCM. The authors suggested that the synthesized composite PCM could be a good candidate for thermal energy storage applications.

Why is PCM important for solar energy storage?

Apart from the advantageous thermophysical properties of PCM, the effective utilization of PCM depends on its life span. Moreover, PCMs which are utilized for different solar thermal energy storage applications are required longer thermal and chemical stability for the extended performance of a system.

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.
