▎ 摘　　要

NOVELTY - A negative electrode comprises a crystalline carbon layer, an amorphous carbon layer having a network structure formed on the crystalline carbon layer and a lithium ion or a lithium carbide compound inserted into the amorphous carbon layer, and a lithium metal electrodeposited around the lithium ion or the lithium carbide compound. USE - Negative electrode for a lithium secondary battery. ADVANTAGE - The electrode is capable of providing a lithium secondary battery having a higher energy density. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method for surface oxidation of crystalline carbon fabric comprises set of carbon fibers by oxygen plasma treatment which involves reacting the surface-oxidized crystalline carbon fabric, the nitrogen precursor, and the metal precursor to form a carbon fabric coated with a metal organic framework, sintering the carbon fabric coated with the metal organic framework at a temperature of 700 degrees C or higher and electrochemically reacting the carbonized carbon fabric in a lithium salt-containing electrolyte to combine the carbonized carbon fabric with a lithium ion or a lithium carbide compound, and electrodepositing the lithium metal around the lithium ion or the lithium carbide compound; and (2) a lithium secondary battery which comprises a positive electrode comprising a positive electrode current collector and a lithium composite oxide-based positive electrode active material layer formed on the positive electrode current collector, a negative electrode, a separator between the positive electrode and the negative electrode and an electrolyte.
