Abstract
The present disclosure is intended to reduce the resistance of a high-loading electrode, to improve the impregnation ability of an electrolyte and thus to improve the rate characteristics of a battery. The present disclosure provides a method for manufacturing an electrode which includes the steps of: a coating step in which electrode active material slurry containing an electrode active material, a binder and a solvent is applied to at least one surface of an electrode current collector; a drying step in which the electrode current collector coated with the electrode active material slurry is introduced continuously to a drying system to dry the coated electrode active material slurry; and a rolling step in which the dried electrode active material slurry is rolled, wherein the coating step includes applying the electrode active material slurry in a loading amount of 500 mg/cmto 1500 mg/cm, and the method further comprises a pattern forming step carried out simultaneously with the drying step and forming a plurality of longitudinal patterns on the surface of the coated electrode active material slurry.
