Abstract

The present invention relates to the fields of heat storage and thermally conductive materials, and discloses a highly thermally conductive heat storage material, a preparation method therefor, and the application thereof, and a composition for preparing a highly thermally conductive heat storage material and the application thereof. The highly thermally conductive heat storage material comprises 11-41 wt % of a carbonaceous part and 59-89 wt % of a graphitic part; for the carbonaceous part, L>18 nm, L>35 nm, d<0.3388 nm, and the degree of graphitization is 60% to 95%; for the graphitic part, L>50 nm; L>80 nm; d<0.3358 nm, and the degree of graphitization is 95% to 100%. The highly thermally conductive heat storage material comprises a carbonaceous part with a specific structure and a graphitic part with a specific structure, and the heat storage material obtained thereby possesses high thermal conductivity and high compressive strength. Meanwhile, the preparation process of the highly thermally conductive heat storage material is simple and cost-effective.
