Design and synthesis of nanostructured cerium oxide anchored on polyaniline electrode for supercapacitors

The current focus of scientific study is to overcome energy storage problems. For this purpose, supercapacitor (SC) was choosen due to its high performance and long stability. The main part of SC is its electrodes. Transition metal oxides (TMOs) are attractive SC electrodes due to their high specific capacitance (C_s) and low cost. While single metal oxide shows smaller surface area, to overcome this issue we fabricate CeO₂/PANI nanocomposite by employing a quick and effective single-step sonification technique. Physical characterization like X-ray diffraction (XRD) was used to analyze structural nature and scanning electron microscopy (SEM) to examine morphology of manufactured materials, specifically CeO₂/PANI nanocomposite. Electrochemical properties of the nanocomposite CeO₂/PANI showed outstanding C_s 1076.05 F/g and E_d (36.47 Wh/kg) at 1 A/g. Furthermore, CeO₂/PANI displays excellent electrochemical capacities with great potential for innovation in the future. The present research shows that composition of polyaniline (PANI) and CeO₂ increases energy storage efficiency and indicates that it can be utilized in SCs in future.
