Usually, one of the first two fundamental states of matter—solid or liquid—will change into the other. Phase change materials for thermal energy storage (TES) have excellent capability for providing thermal comfort in building’s occupant by decreasing heating and cooling energy demands.
1. Introduction Phase change energy storage materials (PCESM) refer to compounds capable of efficiently storing and releasing a substantial quantity of thermal energy during the phase transition process.
Materials with phase changes effectively store energy. Solar energy is used for air-conditioning and cooking, among other things. Latent energy storage is dependent on the storage medium’s phase transition. Acetate of metal or nonmetal, melting point 150–500°C, is used as a storage medium.
Thermal energy storage (TES) development at high temperatures at a reasonable cost for concentrated solar power (CSP) systems. High latent heat is exhibited by phase change energy storage materials (PCESMs), which store heat isothermally during phase transitions.
While existing proposals represent significant advancements in integrating energy storage within construction materials, it is essential to consider the fundamental electrochemical requirements necessary for optimal performance. Electrical conductivity, while crucial, is not sufficient on its own.
CSSCs offer promising potential for integrating energy storage into structural materials, yet key challenges remain. Balancing ionic conductivity and mechanical strength is critical, as increased porosity enhances ion transport but weakens structural integrity.
