Zusammenfassung:The invention relates to the technical field of preparation of composite new materials and in particular to an activated carbon/carbon nanotube/graphene composite material and a preparation method and application thereof. A three-dimensional composite material is prepared from activated carbon, carbon nanotube and graphene. The large specific surface area and the high conductivity of the grapheme and the carbon nanotube are fully utilized. Further, activated carbon barrier carbon nanotube and graphene reunion and stacking are introduced. Thus, the zero-dimensional granular activated carbon, the one-dimensional carbon nanotube and the two-dimensional graphene are uniformly combined through vacuum filtration so as to form a flexible, self-supporting, and three-dimensional porous composite material. When used as a material of a lithium ion capacitor electrode, the composite material is not required to be filled with a conductive agent or a binder, and has the characteristics of self-supporting and flexibility wi
