Energy storage is a promising large-scale technology that effectively addresses the mismatch between energy supply and demand

while also optimizing the energy structure. A comprehensive review of recent advancements in material systems

preparation technologies

and performance characteristics of thermal storage technologies is provided

specifically focusing on chemical thermal storage

sensible thermal storage

and latent thermal storage. The composition

structure

preparation processes

performance characteristics

challenges

application prospects

and future development trends of varions thermal storage meterials are analyzed and discussed. Among these materials

in the process of phase change

the absorption or release of latent heat of phase change for energy storage and release of phase change heat storage stands out due to its significant advantages

including high energy density

ease of reaction control

and exceptional safety and reliability. Moreover

the paper explores further research progress in the realm of phase change energy storage

enhanced heat transfer technology for heat storage systems

and potential applications in different fields.
