The research aims to evaluate the influence of Zn2+ doping on the structural and electrochemical properties of NiCo2O4 spinels for energy storage applications.
Synthesis of Zn-doped NiCo2O4 via microwave-assisted hydrothermal method.
Characterization using XRD, Raman, FEG-SEM, EDS, XPS, and BET analyses.
Evaluation of electrochemical performance in asymmetric supercapacitors.
5% Zn-doped sample (NC5) achieved a specific capacitance of 488.88 F g−1 at 1 A g−1.
NC5 exhibited high energy density of 75.30 Wh kg−1 and power density of up to 3616 W kg−1.
The doping improved structural modifications and increased specific surface area, enhancing charge storage.
