Thermal conductive materials for energy storage industry

What is thermally conductive phase change material?

Thermally conductive phase change material (PCMs), as candidates for thermal management and thermal energy storage, have stimulated great interest for researchers , , . Based on the chemical constituents, PCMs can be divided into two categories: organic and inorganic compounds .

What is the thermal conductivity pathway in composite phase change material?

The internally formed thermal conductivity pathway within the composite phase change material enabled rapid heat diffusion within the material upon exposure to concentrated sunlight, resulting in the acquisition of higher temperature potential energy.

What is a high thermally conductive form-stable phase change material (PCM)?

In this work, take PEG as phase change material, cured and cross-linked mesogenic epoxy as form stable material, high thermally conductive form-stable phase change materials (PCMs) possessing shape memory is designed based on covalent-noncovalent interpenetrating network, which rely on the composition of the two functional species.

What is a high thermally conductive PCM?

High thermally conductive PCMs are usually obtained through blending with thermally conductive fillers, such as carbon-based materials, metallic and ceramic materials , , , , , , , . Yu’ group has developed a high thermally conductive PCMs based on high-quality graphene aerogels impregnated with paraffin wax .

Why is polyethylene glycol good for thermal energy storage?

Among the organic PCMs, polyethylene glycol (PEG) shows strong competitive ability in thermal energy storage because it has desirable thermal stability, adjustable phase change temperature, high latent enthalpy and it is friendly to the environment , , , , .

Why do phase change materials have low thermal conductivity?

Phase change materials (PCM) have low thermal conductivity, which causes the melting and freezing processes to proceed at very low rates ( Khan et al., 2016 ). This limits the availability of the stored energy.
