[0002] Thermal storage technology is an important technology for improving energy efficiency and protecting the environment. It can be used to solve the contradiction between thermal energy supply and demand. It has broad application prospects in the fields of solar energy utilization, "peak shifting and valley filling" of electricity, recycling of waste heat and residual heat, and energy saving in industrial and civil buildings and air conditioning. It has become a research hotspot worldwide. Talc, as a layered silicate mineral material, has stable performance, strong adsorption, and large specific surface area. It can be used as a supporting material for phase change thermal storage materials and used to prepare composite phase change thermal storage materials. However, its poor thermal conductivity makes it have obvious disadvantages compared with kaolin. Therefore, talc is rarely used in phase change energy storage materials. However, the stable crystal form and layered structure of talc make it possible to be used in thermal storage materials. The application of talc in the preparation of thermal storage materials can greatly improve the value of talc and expand the range of raw materials for thermal storage materials, which is of great significance to the development and application of thermal storage materials.
