Abstract

Graphene-based compact nanohybrid films made by alternate deposition of electrochemically exfoliated graphene and mesoporous graphene-conducting polymer nanosheets are constructed for high-energy micro-supercapacitors. They are shown to have a landmark areal capacitance of 368 mF cm(-2) and volumetric capacitance of 736 F cm(-3) .
