Abstract
The present invention relates to a lithium-carbon composite having cavities formed therein and a method of manufacturing the same, the method including adding and mixing an organic solvent having an aromatic ring with a lithium precursor, arranging a pair of metal wires in the organic solvent, forming a lithium-carbon composite in which a carbon body is doped with lithium through plasma discharge in a solution, and annealing the lithium-carbon composite in order to remove hydrogen from the lithium-carbon composite and form cavities in the lithium-carbon composite. Accordingly, a lithium-carbon composite can be simply synthesized using plasma discharge in a solution, and the synthesized lithium-carbon composite can be annealed to thus form cavities therein, thereby increasing the lithium charge and discharge performance of a lithium secondary battery using the lithium-carbon composite.
