Cubic like CoMn2O4 nanostructures as advanced high-performance pseudocapacitive electrode

In this work, a synthesis of cubic-like CoMn2O4 uniform nanostructures with KOH-NaOH involved in the hydrothermal method has been reported. The crystal structure phase purity, functional groups, and morphology have investigated by X?ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), high-reso­lution transmission (HR-TEM) analyses. electrochemical behaviour electroactive material examined for supercapacitors. electrode displays excellent capacitive superior properties. enough free space is beneficial improving performance. exhibits faradaic capacitance highest specific value 762.4 F g-1 at scan rate 5 mV s-1. coulombic efficiency was found to be 91.2 % after 2000 charging-discharging cycles. make prominent contribution performance prepared electrode.
