Morphology-driven ionic pathway engineering in CuCo₂O₄/carbon nanotubes for high diffusion hybrid supercapacitors across diverse electrolyte conditions.

ABSTRACT: In tandem with conductive carbon nanomaterials, redox-active spinel oxides offer a promising strategy to improve the efficacy of electrochemical energy storage devices. Among them, CuCo₂O₄ (CCO) has attracted considerable attention; however, systematic evaluations of its controlled morphology and diffusion dynamics in varied electrolytes remain scarce. In this study, we engineered CCO nanorods, spherical particles, and their nanocomposites with carbon nanotubes (5, 10, and 15 wt%), named CCO-I, CCO-II, and CCO-III, to investigate diffusion behaviour using the galvanostatic intermittent titration technique across different electrolytic conditions, along with key performance parameters. Electron microscopy verified the successful formation of the desired morphologies, w
