Highly super capacitive electrodes made of graphene/poly(pyrrole).

We report on the development and characterization of high performance supercapacitor electrodes synthesized using electrophoretic deposition of graphene, upon which the poly(pyrrole)-layer was electropolymerised. The highly capacitive electrode had a specific capacitance of 1510 F g(-1), area capacitance of 151 mF cm(-2) and volume capacitance of 151 F cm(-3) at 10 mV s(-1).
