NOVELTY - The method for preparing graphene crosslinked boron and nitrogen double-doped carbon aerogel, involves mixing graphene, phenols, aldehydes, boron, amines, catalyst and solvent, crosslinking to obtain organic gel, solvent-exchanging the organic gel, drying at atmospheric pressure to obtain organic aerogel, carbonizing the organic aerogel in inert atmosphere to obtain final product. The amine is selected from melamine, ethylenediamine, triethylenetetramine, hexamethylenetetramine, melamine and/or amide. The boron is selected from boric acid and/or borax. USE - Method for preparing graphene crosslinked boron and nitrogen double-doped carbon aerogel for use in energy storage material, lithium ion battery, super capacitor and electrical absorption material. ADVANTAGE - The environmentally-friendly method enables simple and economical preparation of graphene crosslinked boron and nitrogen double-doped carbon aerogel.
