NiO-Mn3O4 ribbons were synthesized through electrospinning and subsequently compared with NiO nanoparticles Mn3O4 octahedral particles to evaluate their optical electrochemical properties. XRD analysis confirmed the presence of cubic tetragonal phases Mn3O4, respectively, within nanocomposite. UV-Vis diffuse reflectance spectroscopy (DRS) revealed a bandgap 3.53 eV for nanocomposite, while photoluminescence emission quenching indicated an enhancement in surface defects. The exhibited superior performance, achieving specific capacitance 372 F g-1 at current density 1 A g-1, along 94% retention after 3000 cycles 7 g-1. Furthermore, assembled NiO-Mn3O4//AC asymmetric supercapacitor device maximum energy 40 Wh kg-1 power 2400 W kg-1. These findings suggest that hold significant promise high-performance storage devices.
