METHOD FOR PRODUCING ACTIVATED CARBON

A method is for producing activated carbon. The method includes: a) mixing a carbonaceous precursor with chemically activating agents to obtain a feedstock mixture; b) producing activated carbon by heating the feedstock mixture under the atmosphere of a physically activating gas; and c) performing suitable post-activation treatment of the produced activated carbon. Step a) includes in sequence the sub-steps of: i. addition of a first chemically activating agent to obtain an impregnated precursor; and ii. addition of a second chemically activating agent to obtain the feedstock mixture. An activated carbon species is obtainable by the method. The activated carbon species may thus be tuned to have a pore size distribution optimized for use in a carbon electrode.
