MANUFACTURING METHOD OF CARBON AEROGEL, MANUFACTURING METHOD OF SUPERCAPACITOR ELECTRODE, AND MANUFACTURING METHOD OF SUPERCAPACITOR

摘要

PURPOSE: A method for manufacturing carbon aerogel is provided to form gel for a short time, to control a pore size and a pore structure suitable for a supercapacitor electrode, and to enable the drying without the breakage of a pore structure formed inside the aerogel. CONSTITUTION: A method for manufacturing carbon aerogel comprises the steps of: adding magnesium acetate to a mixed solution of formaldehyde and resorcinol; forming chains through a hydrolysis condensation reaction, forming a cluster through a chain bond, and synthesizing a gelled composition through cluster bond; solvent-substituting the composition; aging the solvent-substituted composition; solvent-substituting the solvent included in the composition with carbon dioxide; drying the solvent-substituted composition to form RF aerogel; and performing carbonization of the RF aerogel to synthesize carbon aerogel.
