Fabrication of high-performance of cost effective AgNbO3/rGO nanohybrid via hydrothermal route for supercapacitor applications

The supercapacitor has garnered attention from researchers in recent years which can be related to the rising need for sustainable energy sources. In this study, hydrothermal method is used to synthesize an AgNbO3/rGO nanohybrid for supercapacitor devices. The electrochemical outcomes revealed that AgNbO3/rGO nanohybrid high specific capacitance was measured as 1485 F g(-1) at 1 A g(-1). Furthermore, the obtained result indicates that the small charge transfer resistance (R-ct= 0.71 Omega ) across AgNbO3 and rGO was associated with high ion diffusion efficiency and even after the 5000th charging-discharging cycle and electrode has shown greater stability. This exceptional stability highlights the produced materials' minimal R-ct and outstanding life cycle stability. According to the study's findings, the AgNbO3/rGO nanohybrid electrode has much promise as an electrode in various energy-storing applications.
