Description
In this study, we aimed to develop a novel electrode material for hybrid supercapacitors by synthesizing NiO@Sb2Se3 nanocomposites and evaluating their electrochemical performance. Antimony triselenide (Sb2Se3) nanoparticles were synthesized via a facile melt diffusion technique at 700C, while nickel oxide (NiO) nanoparticles were prepared by a hydrothermal method. Both nanomaterials were composited through ball milling and characterized using SEM, PXRD, SAED, HRTEM, and XPS. Electrochemical studies demonstrated that the composite delivered a specific capacity of 140.26 Fg?1 at 10?mVs?1 and 128.97 Fg?1 at 1 Ag?1 in a three-electrode configuration. A hybrid supercapacitor device assembled with PVAKOH gel electrolyte exhibited a wide potential window (02V), achieving 60.58 Cg?1 at 1 Ag?1, with an energy density of 33.65 Whkg?1 at 2000 Wkg?1, power density, and 82.3% capacity retention over 2000 cycles. These results demonstrate the potential of NiO@Sb?Se? nanocomposites as promising electrode materials for next-generation energy storage devices.
