Study on the electrochemical performance of Ni-doped ZnO nanorods utilized for the high-performance supercapacitor application

The nickel-doped ZnO nanorods have been synthesized through a simple precipitation method. The final product was further characterized through XRD, SEM, HRTEM, FTIR, and electrochemical analysis. The XRD spectrum illustrates ZnO and Ni:ZnO samples show the hexagonal structure. The surface morphology shows the rod-shaped ZnO, and the rods are elongated while addition of Ni. The functional group composition of prepared samples shows the purity of the prepared nanomaterials. The electrochemical performance of the prepared ZnO, 2
