Active polycyclic aromatic hydrocarbon material and a method of manufacturing the same

The present invention is inexpensive coal obtained by heat-treating a raw material as a main component, ion adsorption capacity and / or high ion adsorption capacity per unit electrode volume active polycyclic aromatic per unit weight of the electrode carbide hydrogen material, as well as their preparation. Active polycyclic aromatic hydrocarbon material of the present invention, the oxygen concentration is obtained by heat treating the 25-50% of coal-based raw material in an inert gas atmosphere, and has the following characteristics. (A) H / C ratio (content ratio of hydrogen and carbon atoms) is 0.05 to 0.5, (b) the specific surface area by the BET method 1000~3000m
