A facile and cost-effective approach to fabricate all-in-one supercapacitor electrodes is achieved with copper foam integrated three-dimensional reduced graphene oxide networks. The resulting electrodes display high specific capacitance close to the theoretical value of graphene and good charging–discharging stability.
