Phase difference energy storage layer

Is phase change storage a good energy storage solution?

Therefore, compared to sensible heat storage, phase change storage offers advantages such as higher energy density, greater flexibility, and temperature stability, making it a widely promising energy storage solution.

Are phase change materials suitable for thermal management?

With the increasing demand for thermal management, phase change materials (PCMs) have garnered widespread attention due to their unique advantages in energy storage and temperature regulation. However, traditional PCMs present challenges in modification, with commonly used physical methods facing stability and compatibility issues.

What is thermal energy storage?

Among them, thermal energy accounts for more than 70% of global energy consumption and is the primary form of energy for industrial applications and daily life. Thermal energy storage can be broadly classified into sensible heat storage and latent heat storage (i.e., phase change energy storage).

What are phase change temperature and latent heat?

The phase change temperature and latent heat are two critical parameters for assessing the efficacy of PCMs. These values represent the temperature and energy required to affect a substance's phase change. Table 2 presents the phase change temperature and latent heat for both raw materials and samples.

What is the difference between EA and SP2 thermal storage?

Moreover, within the temperature range of −80 to 80 °C, EA does not exhibit a phase change peak, indicating that it cannot be effectively utilized in everyday phase change thermal storage applications. In contrast, SP2 demonstrates favorable phase change behavior, exhibiting significant latent heat of phase change and minimal supercooling.
