Abstract: The study of thermal storage materials is popular all over the world. This article reviews the latest research progress of the material system, preparation technology and performance characteristics of sensible thermal storage materials, latent thermal storage materials and thermochemical thermal storage materials. The composition, structure, preparation process, performance characteristics, existing problems, application prospects and future developing trends of the thermal storage materials were discussed. Each material has its advantages and disadvantages. In order to overcome the disadvantages of the materials and keep their advantages, development of composite material is the new trend in the research and development of thermal energy material. Current preparation technology of novel composite materials are: ① Preparation of microcapsule/Nano capsule using physical and chemical methods; ② Macro-encapsulation method; ③ Preparation of shape-stabilized composite phase change material using mixed-sintering method; ④ Preparation of composite phase change material using impregnation method. The research and application trends of composite thermal storage materials are discussed in this paper.
