Asymmetric supercapacitor based on nanostructured porous manganese oxide and reduced graphene oxide in aqueous neutral electrolyte
چکیده انگلیسی
A High energy, asymmetric supercapacitor (ASC) has been constructed using porous manganese oxide (MnO2) nanostructures as positive electrode and reduced graphene oxide (RGO) as negative electrode in 1 M Na2SO4 electrolyte. The ASC device exhibits excellent electrochemical performance, when the device is assembled with optimal mass ratio. The energy density is 22.2 W h kg−1 at a power density of 101 W kg−1, when the device is cycled reversibly in the high potential range of 0-2 V. The asymmetric supercapacitor device also exhibits a superior cycling stability with 90% retention of the initial specific capacitance after 3000 cycles.
