Abstract

Disclosed is a method including (a) mixing a precursor of a material for preparing at least one material selected from the group consisting of low crystalline carbon and amorphous carbon with a hydrophilic material, followed by purification to prepare a mixture for coating, (b) mixing the mixture for coating with a crystalline carbon-based material to prepare a core-shell precursor in which the mixture for coating is coated on a core including a crystalline carbon-based material, and (c) calcining the core-shell precursor to carbonize the material for preparing the at least one material selected from the group consisting of low crystalline carbon and amorphous carbon into the at least one material selected from the group consisting of low crystalline carbon and amorphous carbon.
