Abstract

A method of preparing an electrode for a secondary battery, including: (i) a process of preparing a current collector in which through-pores or holes are formed and an electrode slurry containing an electrode active material; (ii) a process of bringing a shielding film into close contact with one surface of the current collector to shield pores or holes on the one surface of the current collector; (iii) a process of coating the electrode slurry on the other surface of the current collector to which the shielding film is not attached, and primarily drying to prepare an interim electrode; (iv) a process of removing the shielding film from the interim electrode; and (v) a process of secondarily drying the interim electrode to prepare the electrode.
