Abstract
Disclosed herein is a method of preparing porous graphene from porous graphite, including 1) thermochemically reacting a highly crystalline carbide compound with a halogen element-containing gas to give a porous carbide-derived carbon; 2) treating the carbide-derived carbon with an acid, thus preparing a carbide-derived carbon oxide; and 3) reducing the carbide-derived carbon oxide. An anode mixture for a secondary battery including the graphene and an anode for a secondary battery including the anode mixture are also provided.
