Performance analysis of supercapacitor with graphene oxide-doped carbon electrodes

Even though supercapacitor possesses superior power density, its main limitation is the relatively poor energy density as compared to other energy storage devices such as battery and fuel cell. One way to enhance the energy density is by increasing its capacitance, which is inevitably depend on its...
