Monolithic porous carbon film has a great potential for integrated supercapacitors due to no polymer binder{,} reduced macropore volume{,} and good adhesion between current collector and active material. It is demonstrated that continuous carbide-derived carbon (CDC) films can be synthesized on various substrates by dry etching. CDC films show high volumetric capacitance of ∼180 F cm−3 in 1.5 M TEABF4/acetonitrile electrolyte.
