| Abstract: | The thermal performance of a shape-stabilized energy storage material Na-2SO-4/SiO-2 is investigated. The thermal analysis by DSC indicates that the material is efficient in energy storage with the thermal energy storage density 180 J/g to 210 J/g, which is 1.5～2.5 times that of sensible ceramics, and is stable to thermal shocking. |
