Abstract

Disclosed herein is a method of manufacturing an electrode for a secondary battery, including: a process of continuously forming two or more slurry coated parts on one surface or both surfaces of metal foil in a second direction which is a longitudinal direction of the metal foil so that a non-coated part which an electrode slurry is not coated is positioned between the slurry coated parts coated with the electrode slurry including an electrode active material in a first direction which is a transverse direction of the metal foil; a process of forming mixture coated parts by drying the slurry coated parts and rolling by a roller; and a process of forming electrode strips by slitting the non-coated part in the second direction, wherein before continuously forming the slurry coated parts, while continuously forming the slurry coated parts, or between continuously forming the slurry coated parts and forming the mixture coated parts, the method further includes a process of forming non-continuous linear slits in the non-coated part of the metal foil in the second direction.
