摘要

The advancement of stable energy storing devices with greater energy density (Ed) is a critical area of study that demands urgent focus. Supercapacitor (SCs) exhibit considerable potential as viable solutions to these issues. Transition metal oxides (TMOs) have attracted substantial interest due to their elevated energy density (Ed). In order to promote rapid electron/ion transit and prevent particle aggregation, a conductive, high-surface-area network was constructed using rGO. Although GdAlO3 has redox-active sites that enable pseudocapacitance and its low intrinsic conductivity restricts its usefulness. This study introduces sonication technique for the synthesis of GdAlO3/rGO nanosheets. The specific capacitance (Cs) of GdAlO3/rGO was 1659.68 F/g at 1 A/g and GdAlO3 (667 F/g) measured by three electrode configuration. Additionally, symmetrical behavior of GdAlO3/rGO is demonstrated by two-electrode systems with Cs of 464.37 F/g with power density (1080 W/kg) at 1 A/g. GdAlO3/rGO two-electrode configuration exhibits exceptional supercapacitive performance. GdAlO3/rGO demonstrated remarkable symmetric two-electrode performance, achieving Ed of 18.80 Wh/kg at 1 A/g. This study suggests that the GdAlO3/rGO possesses potential use in future energy storage systems.
