Method of preparing graphene and anode mixture for lithium secondary battery including graphene prepared thereby

摘要

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.

1. A method of preparing graphene, comprising:
1) thermochemically reacting a 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; wherein 3) is performed by irradiating a blend of the carbide-derived carbon oxide and a thermal conductor with microwaves so as to be reduced.
