Abstract:
In this work, we have synthesized a flexible ZnO-based electrode for its potential applications in energy production and storage devices based on the simple and versatile method. The fabricated ZnO@C foam exhibited enhanced capacitance compared to commercially available Ni foam. The fabrication process involves the synthesis of ZnO nanostructures, deposition of ZnO@C nanostructure on Ni foam, and finally, removing Ni substrate to have ZnO@C foam. Based on cyclic voltammetry, galvanostatic charge-discharge curves and electrochemical impedance spectroscopy, it was concluded that the ZnO@C foam has a suitable electron transfer rate and conductivity. ZnO@C foam provides a high areal specific capacitance of 1120 mF cm-2 at a current density of 4 mA cm-2. The proposed flexible foam has potential applications in the fabrication of solid-state supercapacitors as well as fuel cells.
