Abstract

The present invention relates to a porous carbon material, a preparation method therefor and a use thereof. The specific surface area of the porous carbon material is 1500-3000 m²/g, and the pore size distribution is concentrated in the range 0.6-2.0 nm. The preparation method for the porous carbon material comprises the following steps: (1) acid treatment of montmorillonite; (2) uniformly mixing the acid-treated montmorillonite obtained in step (1) with asphalt and performing carbonization treatment to obtain a carbonized material; and (3) under an inert atmosphere condition, mixing the carbonized material with an activating agent for activation, and then washing and drying. The porous carbon material obtained in the present invention has the advantages of large specific surface area, reasonable pore diameter distribution, high ion transmission speed and the like, and is a supercapacitor carbon material with excellent rate performance.
