▎ 摘　　要

NOVELTY - The method involves dispersing the graphene oxide into the solvent in order to form an electrode active material layer. The electrode slurry is manufactured by mixing the graphene oxide solution and the active material. The manufactured electrode slurry is dried. The electrode slurry is sprayed on a substrate. USE - Method for manufacturing electrode for electrochemical device used like lithium secondary battery. ADVANTAGE - The connectivity between the active material and the substrate can be improved. The energy density of the electrochemical device can be improved. The efficiency of the electrochemical device is increased and the life span of the device can be increased. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) an electrode slurry for electrochemical device; and (2) an electrode for electrochemical device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the scanning electron microscope (SEM) picture illustrates the surface observation result of electrode.
