dc.description.abstractCarbon hollow spheres with similar sizes and surface functionalities but different specific surface areas and shell thickness are prepared to investigate the insight mechanism of energy storage in carbon hollow spheres as electrochemical capacitors utilizing Step Potential Electrochemical Spectroscopy. In 0.5?M Na2SO4 electrolyte carbon hollow spheres provide much better overall capacitance values as compared to high surface area activated carbon due to the better surface area utilization particularly at large scan rates. Carbon hollow spheres exhibited 74% more specific surface area utilization for energy storage as an electrode material in comparison to activated carbon in 0.5?M Na2SO4 solution. When, overall capacitance is divided in to the fragment capacitances in terms of geometric, porous and diffusional contents-
