摘要

The present study demonstrates a simple hydrothermal technique for the fabrication of Cu-doped BaCoO3 nanostructure electrode material. The developed materials, after evaluation of physical characterizations, showed excellent surface area, purity, and morphology. However, electrochemical characterizations of materials took place within 3.0 M KOH. According to experimental results, Cu-doped BaCoO3 material demonstrates an impressive specific capacitance of 1944 F/g over a current density of 1 A/g, and it also shows better cycling efficiency and rate capability. According to chronoamperometry analyses, the Cu-doped BaCoO3 exhibits mechanical stability of 50 h along with excellent mechanical stability (50 h). The greater surface area, small crystallite size, and the synergistic impact within Cu-doped BaCoO3 nanostructure are all linked to excellent electrochemical response. Our findings imply that the synthesized electrode has shown superior electrochemical energy storage capability and has the potential to address other energy storage-related problems.
