Enhanced efficiency of the electrode by doping of neodymium on SmFeO3 for the application of supercapacitor

Abstract

In response to growing demand for the renewable energy generating and storage systems, scientists are trying to synthesized electrode material with exceptional performance. Their primary objective was to develop portable intelligent technology gadgets that could guarantee global energy security. In the reported article, the SmFeO₃ with Nd-doped material was manufactured by cost-effective hydrothermal method for the application of a supercapacitor. The results demonstrate that the existence of larger surface area improves electrical conduction and improves the electrons and ions pathway, resulting in a rapid charge storage device and greatly enhancing the electrical performance. The pristine SmFeO₃ electrode achieved capacitance of 746.3 F g⁻¹, and the Nd-doped SmFeO₃ electrode achieved a heightened capacitance of 1455.9 F g⁻¹ at 1 A g⁻¹. Further, the pristine SmFeO₃ electrode demonstrated low cyclic retention after the 5000th charging/discharging cycles, while the Nd-doped SmFeO₃ electrode demonstrated significant cyclic retention. In addition, the material fabricated attained a significant capacitance of 923.9 F g⁻¹ at 10 mV s⁻¹ during cyclic voltammetry measurements. The exceptional performance of dopant materials suggests their promising conductivity and quick electron/ion transport factors in its exceptional performance made it an excellent electrode for energy storage devices as well as suitability for future-generation energy conversion by surpassing the reliance on perovskite-type structural materials.
