Microporous carbon nano sphere (MCNS) was successfully prepared through the precipitation method of an aromatic isotropic pitch in water without any activation. MCNS was composed of nano spheres with diameter ranging from 100 to 300 nm, which were interlinked together to form a three-dimensional network in a MCNS particle. There were a number of mesopores among the nano carbon spheres, while micropores were developed within a nanosphere. These structural features enabled MCNS to have high specific capacitance as high as 154 F g-1 by cyclic voltammetry (CV) and capacitance per surface area of 0.62 F m -2 as an electrode for the inorganic capacitor, respectively.
