Graphene based supercapacitor fabricated by vacuum filtration deposition

Abstract. A novel method involving vacuum filtration deposition (VFD) of graphene suspension is developed in this study to fabricate graphene based nickel foam electrode for supercapacitor. Acid-treated graphene nanosheets in a suspension can be easily deposited in the pores of nickel foam in large quantity using this method, thus producing supercapacitors with large energy capacity.
