▎ 摘　　要

NOVELTY - The negative electrode has an artificial graphite-based active material, where the electrode density is provided. The artificial graphite-based active material is provided with the artificial graphite with a graphitization degree of 90 percent or greater, where the artificial graphite of the artificial graphite-based active material is provided as an unassembled artificial graphite. The artificial graphite of the artificial graphite-based active material is provided as a graphene interplanar spacing. USE - Negative electrode for a lithium secondary battery (Claimed). ADVANTAGE - The artificial graphite-based active material is provided with the artificial graphite with a graphitization degree of 90 percent or greater, and hence enables forming a stable surface electrolyte interface layer during the initial charging to prevent the reduction of electrolyte solvents and maintains the high efficiency to minimize the consumption of lithium ions contained in a positive electrode. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for manufacturing a negative electrode for a lithium secondary battery; and (2) a lithium secondary battery with an electrolyte. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the electrode density according to a graphitization degree of an unassembled artificial graphite. (Drawing includes non-English language text).
