Abstract
The present invention provides a method for preparing an electrode for a secondary battery, including the steps of: (i) mixing and kneading an active material, a binder, and a conductive material together with a solvent to prepare a slurry in the form of a paste having a solid content of 70 to 90 wt %; (ii) positioning the slurry in the form of a paste on a current collector; and (iii) passing the current collector through a rolling apparatus together with the slurry in the form of a paste to simultaneously press it while forming an electrode coating layer on the current collector.
