NOVELTY - A graphene composite aerogel comprises 50-150 pts. wt. resorcinol, 80-200 pts. wt. formaldehyde, 0.1-1 pt. wt. nano-material, 0.05-0.15 pt. wt. catalyst, and 100-300 pts. wt. graphene. USE - Graphene composite aerogel for cathode of lithium battery (claimed). ADVANTAGE - The graphene composite aerogel has high dispersion stability, high specific surface area, large porosity, wide pore size distribution, and excellent conductivity, and is prepared by simple, economical and environmentally-friendly process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of graphene composite aerogel, which involves (S1) adding a certain amount of catalyst and nano-material into water, and uniformly dispersing for 3-7 hours, (S2) adding resorcinol and formaldehyde to the step (S1) according to a certain proportion, and mixing to obtain mixed solution, (S3) ultrasonically processing the graphene oxide in deionized water with 2500-3500 W for 0.5-2 hours to obtain graphene oxide dispersion liquid with concentration of 0.1-5 mg/ml, (S4) dispersing the obtained graphene oxide dispersion liquid in the mixed solution of (S2), and reacting at 80-100 degrees C for 1-5 hours, (S5) soaking the continuous porous foam material in the solution obtained in the step (S4), taking out the continuous porous foam material after filled in the solution, sealing the gel, and freeze-drying to obtain dry gel, and (S6) placing the dry gel in a high temperature atmosphere furnace of inert gas, and carbonizing at high temperature for a period of time.
