Abstract: The thermal performance of a shape-stabilized energy storage material Na₂SO₄/SiO₂ is investigated. The thermal analysis by DSC indicates that the material is efficient in energy storage with the thermal energy storage density 180J/g to 210J/g, which is 1.5～2.5 times that of sensible ceramics, and is stable to thermal shocking.
