dc.description.abstract | Iron oxide (Fe2O3) nanoparticles and reduced graphene oxide (rGO) sheets were supersonically sprayed onto a nickel substrate to fabricate flexible supercapacitors. The supersonic impact velocity was adjusted by varying the air chamber pressure from 2 to 6 bar, which facilitated the self-healing of Stone-Wall defects in rGO sheets. Supersonic spraying caused exfoliation of the rGO sheets, which in turn increased the surface area and adherence of the Fe(2)O(3 & nbsp;)nanoparticles. The optimal case exhibited a specific capacitance of 1.44 F.cm(-2) at a current rate of 1.5 mA.cm(-2) and the energy density was 14.23 mW.cm(-3) at 250 mW.cm(-3). The width of the potential window increased to 1.4 V, implying a significant increase in the energy storage capability. The energy density of the supersonically sprayed Fe2O3/rGO electrode also showed no signs of deterioration even when the increased current density interfered with the electrode performance. | - |
