The storage of heat energy has great practical significance in solving the intermittence and fluctuation problems of energy acquisition, as well as the mismatch between energy production and social energy consumption in time and space. Phase change thermal energy storage technology is an effective means to improve energy utilization, it is based on phase change materials to realize energy storage and release. The research of thermal energy storage materials is the key to achieve high efficiency storage of thermal energy. In the field of medium and high temperatures thermal energy storage, metals have obvious advantages as thermal energy storage materials. Among them, aluminum based phase change thermal energy storage materials have the advantages of suitable phase change temperature, high energy storage density, high thermal conductivity and small phase change volume. It is widely used in the field of thermal energy storage. This review starts with the research status of aluminum based metal phase change thermal energy storage materials, the process factors affecting the composition and uniformity of aluminum based phase change thermal storage materials are summarized.The phase change thermal storage performance and thermal cycling stability of typical aluminum based phase change thermal storage materials are introduced.Then the corrosion mechanism of aluminum based alloy on vessel is analyzed. Finally the compatibility of aluminum based phase change thermal storage materials with corresponding containers at high temperature is summarized.At last,the existing problems in the research of aluminum based phase change materials are summarized and the corresponding improving scheme is proposed.
