The invention relates to a high-altitude low-air-pressure heat storage and release performance test device for a solid heat storage material. A low-pressure high-temperature test cavity is separately connected with a low-pressure low-temperature power cavity and a cooling unit through pipelines; and the data acquisition and control unit is used for acquiring measurement signals of a heat storage material test area and a pipeline, determining low-pressure environments corresponding to different altitudes, and simultaneously obtaining convective heat transfer characteristics of rarefied air and the surface of the heat storage material. Heat storage materials with different formulas, manufacturing processes, monomer structures and assembly structures are placed in a solid heat storage material testing area, the heat exchange characteristics of the heat storage materials in different air pressure environments are tested, and the heat storage and release characteristics of the same material at different altitudes
