Abstract: The research of expanded graphite matrix composite phase change material is the highlight in energy storage science field, for its properties of high thermal conductivity, high energy storage density and no liquid leakage during the phase change process. This paper discusses the properties and classification of phase change materials used in thermal storage system, and the preparation methods of expanded graphite and its composite phase change material are briefly analyzed, finally reviewed the domestic and overseas research progress of expanded graphite matrix composite phase change materials with the working media of waxes, fatty acids, eutectic mixture, polyethylene glycol and acetamide.

Key words: expanded graphite, phase change material, thermal energy storage technology
