Electrode Coating Apparatus, And Electrode Manufacturing Method Using Same

Abstract: The present invention relates to an electrode drying apparatus and an electrode manufacturing method using same. The electrode drying apparatus induces static electricity on the back surface of an electrode current collector, which is coated with an electrode slurry, so as to have a charge opposite to the charge of an ionic binder included as a binder in the electrode slurry, so that the movement of the binder to the surface of the electrode slurry can be prevented even if a solvent volatilizes during drying of the electrode slurry, and thus the adhesiveness between an electrode mixture layer, which is formed by drying of the electrode slurry, and the electrode current collector is remarkably improved.
