▎ 摘　　要

NOVELTY - The method involves patterning one-step reduction by a space-shaped femtosecond laser. The reduced graphene oxide and manganese dioxide composite electrode is processed. The mixed film is prepared of graphene oxide and manganese acetate. The mixed film obtained in graphene and manganese dioxide is placed on the substrate. The light field of a desired electrode shape is formed at the objective lens to obtain a shaped femtosecond laser, after the femtosecond laser is phase-modulated. The patterning of the light field is finally realized, after loading into the spatial light modulator. USE - Method for fabricating space-forming femtosecond laser processing graphene-based supercapacitor. ADVANTAGE - The space-forming femtosecond laser processing graphene-based supercapacitor fabricating method realizes high energy density and high specific surface area, and overcomes the shortcomings of being difficult to be small and integrated, and realizes high-efficiency processing of various shapes of supercapacitors. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the space-forming femtosecond laser processing graphene-based supercapacitor fabricating process.
