▎ 摘　　要

NOVELTY - Nitrogen, sulfur-doped hierarchical macroporous/mesoporous graphene comprises honeycomb three-dimensional structure formed by stacking graphene sheets, and macropores, and/or mesopores are distributed on the graphene sheets, where the size of the macropores on the honeycomb three-dimensional structure is 0.5-5 microns, the size of macropores distributed on the graphene sheet is 50-100 nm, and the size of mesopores is 2-50 nm. USE - The nitrogen, sulfur-doped hierarchical macroporous/mesoporous graphene is useful in lithium-ion battery and sodium ion battery (claimed). ADVANTAGE - The hierarchical macroporous/mesoporous graphene has good lithium storage and sodium storage circulation and multiplying power performance. The method has low cost, does not need to add acid and alkali, strong oxidant and etching agent, and is easy to synthesize in large scale. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of the hierarchical macroporous/mesoporous graphene doped with nitrogen and sulfur using asphalt comprising at least one of petroleum asphalt, coal tar asphalt and intermediate phase asphalt, nitrogen source comprising at least one of melamine, urea, thiourea, polyaniline, phenylenediamine and dopamine, and the liquid aromatic hydrocarbon is at least one of single ring aromatic hydrocarbon and bicyclic aromatic hydrocarbon.
