摘要

Supercapacitors and other alternative energy storage technologies must be developed as soon as possible due to the substantial reliance on renewable energy sources throughout the last few decades. On this context, supercapacitors consisted of highly efficient nanocomposite based electrodes, are gaining considerable attention for energy conservation purposes. SmFeO3/rGO nanocomposite was fabricated using an effective sonication approach. The SmFeO3/rGO composite material exhibits a very high capacitance value of 1854 F g−1 at a current density of 1 A·g−1, cyclic stability up to 5000 cycles. The solution resistances are observed to be 1.01 Ω during electrochemical impedance measurement. SmFeO3/rGO nanocomposite has enhanced electrochemical characteristics compared to individual fabricated pristine SmFeO3 owing to its negligible resistance, enhanced surface area and quicker movement of electrolytic ions. In the future, electrodes composed of the SmFeO3/rGO serve as electrodes for supercapacitors energy storage devices.
