N2 - Sustainable, reliable and affordable energy sources are crucial in meeting the world's energy needs amid various climate change and energy availability disparities. Supercapacitors are the most sophisticated energy-storage technology available and becoming better by changing the composition of their electrodes. The current work reports the fabrication of SrCrO3/rGO nanohybrid by Sonication process as a high-performing and efficient electrode material for supercapacitor (SCs). The physical analyses have revealed that the synthesized SrCrO3/rGO nanohybrid showed a pure crystalline phase and enhanced surface area. Furthermore, electrochemical methodologies were employed to examine the electrochemical characteristics of the synthesized nanohybrid. The specific capacitance of the newly created SrCrO3/rGO nanohybrid was 1180.6F/g at 1 A/g, which was greater than the specific capacitance of pure SrCrO3 electrode (523.5F/g). Following 5000th cycle of the stability test at 5 mV/s, the nanocomposite showed a slight drop in the area of its CV curve with a 30 h stability. Furthermore, the SrCrO3 and SrCrO3/rGO nanocomposite showed a specific energy of 20.3, 45.5 W/kg and specific power of 263.4 and 264.5 Wh/kg at 1A/g value, respectively. Several results showed that the presence of rGO in the SrCrO3/rGO nanohybrid improved the ion/electron mobility and electric conductivity, which resulted in a fast charge-storing method and greatly improved the electrochemical activity of the nanohybrid in comparison to SrCrO3. The remarkable performance of the SrCrO3/rGO nanohybrid illustrated its advantageous prospects for the next generation of energy storage technology.
