Enhanced electrochemical performance of copper oxide nanobeads a potential electrode material for energy storage devices
2020
Abstract Here we report, a simple co-precipitation method for the synthesis of copper oxide (CuO) nanobeads. Many characterization techniques such as Powder X-ray diffraction (P-XRD), Field Emission Scanning Electron Microscope (FESEM) and Fourier Transform Infrared Spectroscopy (FTIR) confirms the purity of CuO nanostructure while electrochemical studies exhibit a specific capacity of 69.1 mAhg-1 (771 Fg-1) at 0.83 Ag-1 current density which is higher than other reported bare CuO nanostructure. Furthermore capacity retention of 82.1 % over 1000 charge/discharge cycles and low value of charge transfer resistance (Rct) confirms its potential to be used as an electrode material for energy storage devices.
