The invention relates to an activated carbon comprising a hierarchical hole channel structure and a production method thereof and belongs to the novel carbon material production field. The production method is based on the activation of the mechanical force auxiliary potassium carbonate on heavy carbon sources such as petroleum coke, coal, or phenolic resin. The production method comprises the specific steps of mixing the screened heavy carbon source powder with the potassium carbonate and obtaining the activated carbon for a super capacitor through the ball-milling, activation, washing and drying process. According to the activated carbon comprising the hierarchical hole channel structure and the production method thereof, the activated carbon is large in specific surface area, is of a hierarchical hole channel structure, and the like; the technical route that the potassium carbonate serves as a pore forming agent to produce the activated carbon is implemented and the problem that raw materials such as the petroleum coke and the coal cannot be activated by the potassium carbonate is solved; compared with potassium hydroxide and other activation methods, the corrosion is low, the adaptability to the raw materials is high, the specific surface area is large, the mesoporous pore capacity is large, the enlargement is easy, and the like; the novel activated carbon can be widely applied to the adsorption, catalysis, electrochemical energy storage and other fields and accordingly the application prospect is wide.
