Research Progress on the Development and Application of Chemical Heat Storage Materials

Chemical heat storage, as the core technology of chemical energy and heat energy interconversion, is one of the most significant energy storage technologies in the 21st century. Compared with traditional latent heat storage, chemical heat storage has enhanced by orders of magnitude in energy storage density, and its superiority in operating temperature range as well as stability of materials is outstanding. This paper is oriented toward several primary chemical heat storage materials, such as metal hydroxide, metal hydride, metal carbonate, crystalline hydrate and metal salts ammonate. We put emphasis on elaborating the application mechanism and operating condition of each material. We also analyzed the research status as well as scientific and application problems of those materials that need to be solved urgently. We strongly believed that the main development direction of chemical heat storage technology in the future lies on the optimization and synthesis of composite materials and doped materials.
