Development of Nd doped AlFeO3 electrode material for supercapacitor applications

Abstract

The development of metal oxides nanoscale structures with enhanced chemically active surfaces, faster ion/charge transport kinetics with shorter ion-diffusion paths is demand in the field of supercapacitor. The issue of transition metal oxides has been successfully resolved through the utilization of metal doping, which concurrently enhances surface area, accelerates ion migration and enhances thermal and structural stability. The Nd doped AlFeO3 electrode substance fabricated hydrothermal process for electrochemical properties. The different analytical tools determined physical and electrochemical characteristics of prepared electrode material. Nd@AlFeO3 electrode material demonstrates specific capacitance of 1326 F/g at 1 A/g measured from galvanostatic charging/discharging plot which maintains remarkable stability after 5000th cycles. The Nyquist plot determines lower charge transfer resistance of Nd@AlFeO3 electrode material (1.15 Ω). The Nd@AlFeO3 electrode material exhibited improved electrochemical properties which makes it promising candidate for integration into supercapacitor devices.
