Electrochemical analysis of carbon@nickel core shell nanostructures for energy applications

This research delves into the optical and electrochemical properties of synthesized samples, analyzing their behavior in electrolytes and thin films. Structural analyses confirm the formation of C@Ni(OH)₂ and C@NiO core-shell nanostructures. The optical response of these structures hints at their suitability for solar technologies. The contrast in resistance between the electrolyte and thin film suggests enhanced capacitive charge and resistance. Randle’s circuit analysis reveals promising configurations, with the thin film showing potential for improved performance in solar applications despite high charging. The unique charging characteristics of these nanostructures, including multilayer charging processes, position the thin film for use in capacitors. Despite high charging, the electrolyte resistance remains lower, promising efficient capacitor development. These findings not only deepen understanding of electrochemical characteristics but also pave the way for optimizing solar cells and capacitor. The research suggests advancements in energy storage technology and exploration of charging mechanisms for practical applications in capacitors.
