▎ 摘　　要

NOVELTY - Graphene-type carbon material wrapped with nickel disulfide nanocrystals comprises graphene-type carbon, which is a three-dimensional ordered macroporous structure composed of a carbon matrix composed of nano-onion carbon. The nickel disulfide nanocrystals are uniformly embedded in a carbon matrix. USE - The graphene-type carbon material wrapped with nickel disulfide nanocrystals is used to anode materials of sodium-ion batteries and sodium-ion hybrid capacitors. ADVANTAGE - The graphene-type carbon material has good reversible capacity, excellent rate performance and cycle performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene-type carbon material, comprising complexing the nickel salt and the complexing agent in water to obtain the precursor solution, dipping the colloidal crystal microsphere template into the precursor solution, taking out and drying to obtain the precursor, roasting and cooling the precursor in an inert gas atmosphere to obtain a calcined product, and co-calcining the calcined product and thiourea to obtain graphene-type carbon materials.
