Description
The global transition toward sustainable energy is currently hindered by the "energy-power gap" in storage technologies, where traditional batteries lack power density and standard capacitors lack energy storage capacity. In the quest of finding solutions, supercapacitors attract more interests due to their fast charge-discharge capability and high-power density, however, low-energy density limit their applications. This research investigates the synthesis and electrochemical performance of a novel Molybdenum (Mo) doped CeMgO3 perovskite for high-performance supercapacitor applications. Samples of pristine CeMgO3 and 1%, 3%, 5% and 7% of Mo doping of CeMgO3 perovskite were synthesized using hydrothermal method. Structural, morphological and surface area properties of CeMgO3 and Mo doped CeMgO3 will be investigated using X-ray Diffraction (XRD), Scanning Electron Microscope (SEM) coupled with Energy Dispersive X-ray Spectroscopy and Brunauer-Emmett-Teller (BET) Surface Analyzer. Furthermore, electrochemical performance of the pristine CeMgO3, Mo doped CeMgO3 will be explored through Cyclic Voltammetry (CV), Electrochemical Impedance Spectroscopy (EIS) and Galvanostatic charge-discharge (GCD) for possible supercapacitor applications. SEM results indicate that CeMgO3 formed agglomerated spherical nanoparticles, which upon doping it with Mo, particle sizes increased with increasing concentration. EDX confirmed the presence of Ce, Mg and O in pure samples and Mo in doped samples. The findings of this study will have a significant contribution in the development of supercapacitors.
