Abstract

Abstract : A 2D mesoporous carbon/graphene nanocomposite shows a very high power density of 135 kW kg −1 at an energy density of 60 W h kg −1 . Abstract : A two-dimensional highly ordered mesoporous carbon/graphene nanocomposite (MCG) was synthesized by replicating a KIT-6/graphene nanocomposite. The MCG exhibited a high Brunauer–Emmett–Teller surface area of 1179 m 2 g −1 and a large total pore volume of 0.94 cm 3 g −1 . On account of its large surface area and high electrical conductivity with 2D morphology, MCG showed a very high specific capacitance of 276 F g −1 at 1 A g −1 and maintained 86% of initial capacitance at 100 A g −1 in 1.0 M TEABF4/AN.
