High performance Mn doped ZnO loaded rGO electrode and its practical application as an electrode for self-charging supercapacitor device
In this work, the supercapacitor performance of rGO is enhanced via loading Mn (0.05, 0.075, and 0.1 M) doped ZnO. The morphology, structure, and constituent elements of the material are investigated via material characterization tools. The electrodes are fabricated over a conductive fabric (CF) and their performance is investigated via electrochemical techniques. Mn (0.075 M) doped ZnO loaded rGO displayed the lowest bulk resistance, highest specific capacitance, excellent cyclic stability, and good rate performance. The electrode showed a specific capacitance of 487.3 F g−1 at 2 A g−1 with 81.2 % cyclic stability for 10,000 cycles. A self-charging supercapacitor device is also developed in this study using an Mn (0.075 M) doped ZnO loaded rGO electrode. The device displayed output potential under the influence of external force, bending, and twisting at certain angles. The performance of rGO is successfully enhanced and a potential electrode material for self-charging supercapacitor is developed.
