Facile microwave synthesis of cerium molybdate as an electrode material for high-performance supercapacitor application in redox-additive electrolyte
Developing cost-effective and eco-friendly supercapacitors has attracted increasing attention in high-energy supercapacitors constrained by the limited candidates. In this work, cerium molybdate is prepared by facile microwave combustion method. Powder XRD and FTIR analyses confirm the formation of Ce(MoO4)2. The nanostructure morphology and elemental ratio have been studied by FE-SEM equipped with EDS. The electrochemical behavior is assessed in three and two-electrode systems exhibiting a high specific capacitance (Csp) of 582.34 F/g at 6 A/g (3-electrode system). Asymmetric device displays maximum Csp of 242.64 F/g and energy density of 75.83 Wh/kg at 1 A/g. The results suggest that the prepared Ce(MoO4)2 nanoparticles can be used as a potential candidate for high-performance energy storage applications.
