Nanostructurally fabrication of nickel oxide-interfaced carbon nanotubes for supercapacitors and exploration of electrochemical correlation via computer vision techniques and artificial intelligence

초록

Carbon-based nanoparticles continue to draw greater attention due to their unique physicochemical properties that make them suitable for use in sensors, supercapacitors, and batteries. Nickel oxide/carbon nanotube composites (NiO/NMWCNT) were prepared via hydrothermal reaction for supercapacitor materials. Nickel oxide formed a monoclinic phase, according to an XRD analysis. The elemental makeup and morphological characteristics of these manufactured electrode materials were then investigated using HR-TEM analysis. The constructed composite electrode was then examined using CV analysis for use in supercapacitors with 1 M KOH electrolyte. The outcomes demonstrate enhanced electrochemical capacitance (633 F/g at 10 A/g) and electrode stability, with 86 % maintenance up to 5000 cycles. Furthermore, the HR-TEM image specimen of the composite was analyzed using pixel-based computer vision and AI algorithms to quantify the porosity of the composite and investigate the possible enhancement in electrochemical correlation. © 2024
