A review of the performance and application of molten salt-based phase change materials in sustainable thermal energy storage at medium and high temperatures

Growing energy demand and environmental pollution issues are placing greater demands on sustainable thermal energy storage. Research indicates that molten salt phase change materials (MSPCMs) represent a promising alternative for thermal energy storage (TES), effectively addressing the energy supply-demand imbalance. These salts typically have a range of excellent properties, such as high energy storage density, easy availability, and minimal environmental impact. Nevertheless, the widespread application of molten salts is considerably constrained in both industrial and commercial contexts due to their low thermal conductivity (TC) and leakage problems during phase transitions. Based on this, this paper…
