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.

Abstract: The present invention relates to a Ti-included oxide dispersion strengthened copper alloy and a method for preparing oxide dispersion copper by an internal oxidation Ti-included copper alloy, which thus allows spheronization and refinement of the oxides, and reduction of distance between the oxides. According to the present invention, there is provided oxide dispersion copper having excellent hardness and tensile strength as well as electrical conductivity by performing spheronization and refinement for Ti-included oxide and thus further reducing the distance between oxides.
