Résumé en anglais

Carbon derivatives are the leading materials used as electrodes in double-layer supercapacitors. the present work reports the preparation of nanocarbon from two natural sources, cupuaçu (or cupuassu) shell, and bacterial nanocellulose. The nanocarbons’ microstructure and physical-chemical properties were characterized by BET-specific surface area, transmission electron microscopy, pore size, and Raman spectroscopy. From the obtained materials, electrodes were manufactured to analyze their electrical and electrochemical properties. The results of the electrochemical properties were related to the physicochemical and textural properties of the materials. In particular, the carbon derived from bacterial nanocellulose demonstrated excellent performance, with a high-power density of 9387 W/kg, an energy density of 1.85 Wh/kg, and a specific capacitance of 59 F/g. These electrochemical properties indicate that the prepared nanocarbons are highly suitable for application in electrochemical capacitors, offering promising potential due to their favorable power and energy densities, which are closely related to their optimized surface area and pore structure.< Réduire
