Anodic NiO nanoparticles as high-performance asymmetric supercapacitor devices in hybrid electrolytes.

ABSTRACT: The energy storage capabilities of a supercapacitor are critically determined by the choice of electrode materials, electrolytes, and synthesis methods, making their appropriate selection indispensable for improving the electrochemical performance. This study presents the synthesis of nickel oxide (NiO) nanoparticles (NPs) by a low-cost, straightforward, and one-step anodization approach. FESEM, HRTEM, XRD, XPS, BET analysis, FTIR, and Raman spectroscopy were performed to determine the morphology, crystal structure, oxidation states, specific surface area, functional groups, and vibrational and rotational states of NiO NPs. The fabricated electrode was investigated for capacitive application in 1 M KOH, Na₂SO₄ and hybrid electrolytes. The electrode showed an enhanced
