NOVELTY - Porous carbon material of a core-shell structure comprises a core comprising a stack structure of carbon sheets, and a carbon-containing shell surrounding the core. USE - The porous carbon material of the core-shell structure is useful in a sulfur-carbon composite used in a lithium secondary battery (claimed). ADVANTAGE - The porous carbon material of the core-shell structure meets the need for a battery system capable of driving electrodes of high loading and low porosity and can significantly improve capacity, charge/discharge, and lifespan characteristics of the lithium ion battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for manufacturing the porous carbon material of the core-shell structure involving (a) mixing a carbon precursor having a melting point of 130-350 degrees C with at least one particle chosen from basic zinc carbonazate (BZC), zinc (II) metal oxide-organic framework, and porous structures zinc oxide as a template, (b) heating the mixture to 120-350 degrees C to infiltrate the carbon precursor into the mold, (c) forming a core-shell shape while removing the mold by heating the structure in which the carbon precursor has penetrated into the mold to 600-900 degrees C and (d) heating the core-shell structure at 800-1500 degrees C to vaporize and remove zinc impurities; and (2) a sulfur-carbon composite comprising the porous carbon material and a sulfur component in the core-shell structure.
