Graphenated carbon nanotubes (g-CNTs) were investigated as the electrode support in MnO2 composite cathodes for aqueous asymmetric supercapacitors. The electrode performance could be tuned by optimizing the density of graphene foliates on the g-CNTs, which enabled geometric/morphologic control over the MnO2 electrodeposits. The synergy and optimization of the g-CNT hybrid structure led to a high specific capacitance (640 F/g) at high MnO2 specific loading (2.3 mg/cm2), thus creating a unique pathway toward improved practical performance.
