Shell high temperature heat storage material comprising a top shell material core, a porous first shell surrounding the core, and a second shell surrounding the first shell. The core-shell high-temperature heat storage material according to the present invention can store and discharge latent heat through the phase change of the core material inside the particles, and thus, more energy can be exchanged than the heat storage material having no phase-change core material. In addition, the core-shell high-temperature heat storage material according to the present invention is excellent in particle durability in a high-temperature environment because a carbon layer and a metal layer are formed outside the phase-change foreign material. Therefore, the core-shell high-temperature thermal storage material according to the present invention can be used as a heat storage material at high temperature due to its high heat storage ability and particle durability, and can be applied to various application fields as a heat storage material. |
