Abstract
Provided is a preparation method of a metal oxide doped monolith carbon aerogel for a high capacitance capacitor, the including: preparing a monolith carbon aerogel by performing a thermal decomposition of a moist gel dried in condition of a atmospheric pressure and a room temperature in a nitrogen atmosphere; impregnating the monolith carbon aerogel into alcohol where a metal precursor is dissolved; and calcinating the monolith carbon aerogel where the metal precursor is impregnated in an atmospheric atmosphere. By impregnating the metal oxide into the monolith carbon aerogel, a limit of capacitance may be enhanced using a pseudo capacitance effect by an interfacial oxidation reduction reaction.
