    Abstract: Disclosed is a method for manufacturing an electrode, which comprises drying an electrode sheet including a current collector and an electrode active material slurry coated to the current collector and containing an electrode active material, a binder and a solvent, wherein the electrode sheet is dried by a mid-infrared lamp which irradiates mid-infrared rays with a wavelength of 1 μm to 3 μm to the electrode sheet, and a surface temperature of the electrode sheet has a constant region in the range of 50° C. to 70° C. Since an electrode is dried by using a mid-infrared lamp, the electrode may be uniformly dried, and an adhesion force between the electrode active material layer and the current collector may be greatly improved, which allows great enhancement of characteristics of a battery to which the electrode is applied.
