In this work, carbon spheres having an average particle diameter of 0.6 µm were prepared by a simple hydrothermal synthesis method using glucose as precursor. These carbonized and graphitized at different temperatures, namely 1200 °C, 2100 2400 °C 2800 in order to study the impact structural properties, i.e. morphology degree graphitization, on TFSI - anion intercalation behavior into these carbons used cathode material dual-ion cells. The properties spheres, such size, surface morphology, specific area crystallinity after heat-treatment are characterized scanning electron microscopy, X-ray diffraction nitrogen adsorption measurements. Consequently, characteristics correlated electrochemical results for application context, high graphitization is mandatory achieve reversible capacity.
