Method for treating activated carbon and activated carbon treated by said method

Abstract

The present invention relates to a method for treating activated carbon, comprising the steps of: (a) reducing a particle size of a starting activated carbon to obtain activated carbon powder; (b) subjecting the activated carbon powder obtained from step (a) to a mechanofusion process to obtain activated carbon having spherical particles; and (c) subjecting the activated carbon having spherical particles obtained from step (b) to a heat treatment. Preferably, step (c) is carried out at a temperature in a range of 600-1,000° C. for 1-5 hours. The invention further relates to activated carbon produced by the above-described method, as well as to an energy storage device comprising such activated carbon.
