NOVELTY - The present invention provides a method for preparing a composite organic electrode, which includes the following steps: step (a): dispersing graphene and carbon nanotubes in a dispersant to form a mixed solution; step (b): combining a conductive base The material is immersed in the mixed solution to obtain a surface-treated conductive substrate; and step (c): the surface-treated conductive substrate is immersed in a manganese-containing electrolyte and electrodeposited to obtain the composite electrode. The composite electrode of the present invention has an excellent specific capacitance value and can be used in a super capacitor to further improve the cycle life of the super capacitor.
