Thermal conductive energy storage materials

Why is thermal conductivity important for phase change energy storage systems?

Thermal conductivity is a key parameter for phase change energy storage systems to measure how fast or slow the energy is transferred. Many researchers in China and abroad have done a lot of work on improving the thermal conductivity of phase change materials.

Is high temperature thermal energy storage a good option?

High temperature thermal energy storage is one promising option with low cost and high scalability, but it is hindered by the inherent complexity of simultaneously satisfying all of the material requirements. Here we design a class of ceramic–carbon composites based on co-optimizing mechanical, electrical, and thermal properties.

Are PCMS thermally conductive?

However, PCMs suffer from very low thermal conductivity and the risk of leakage when in the liquid phase. To address these issues, highly thermally conductive fillers such as carbon-based materials [8, 9, 10], metal micro/nanoparticles [11, 12] and ceramic materials [13, 14] have been incorporated into PCMs to enhance their thermal conductivity.

How to improve the thermal conductivity of a latent heat storage system?

Besides, a great deal of theoretical and experimental studies were carried out to investigate the heat transfer mechanism of various latent heat storage systems . At present, the main methods to improve the thermal conductivity of PCM is to add high thermal conductivity matrix and chemically treat the surface of additive.

How to improve thermal conductivity and heat transfer properties?

Several researchers have investigated these FAs and tried to improve their thermal properties, mainly by adding different high conducting fillers, such as graphite, metal foams, CNTs, graphene etc. In most cases, these fillers improved the thermal conductivity and heat transfer property but reduce the heat storage capacity considerably.

Are fatty alcohols a good thermal energy storage material?

Provided by the Springer Nature SharedIt content-sharing initiative Fatty alcohols have been identified as promising organic phase change materials (PCMs) for thermal energy storage, because of their suitable temperature range, nontoxicity and can be obtained from both natural and synthetic sources.
