Abstract
Disclosed is a method of preparing a carbide-derived carbon having high ion mobility for use in a lithium battery anode material, a lithium air battery electrode, a supercapacitor electrode, and a flow capacitor electrode, including thermally treating a carbide compound in a vacuum, thus obtaining a vacuum-treated carbide compound; and thermochemically reacting the vacuum-treated carbide compound with a halogen element-containing gas, thus extracting the element other than carbon from the vacuum-treated carbide compound, wherein annealing can be further performed after thermochemical reaction. This carbide-derived carbon has a small pore distribution, dense graphite fringe, and a large lattice spacing and thus high ion mobility, compared to conventional carbide-derived carbon obtained only by thermochemical reaction with a halogen element-containing gas.
