METHOD FOR MANUFACTURING ELECTRODE USING CURRENT COLLECTOR HAVING PENETRATION-TYPE PORES OR HOLES FORMED THEREON

Document Type and Number:

WIPO Patent Application WO/2018/044013

Kind Code:

A1

Abstract:

The present invention relates to a method for manufacturing an electrode for a secondary battery, the method for manufacturing an electrode for a secondary battery comprising the steps of: (i) preparing a current collector and an electrode slurry, respectively, the current collector having penetration-type pores or holes formed thereon, and the electrode slurry comprising an electrode active material; (ii) shielding the pores or holes on one surface of the current collector by closely adhering a shielding film to the one surface; (iii) manufacturing a temporary electrode by coating the electrode slurry on the other surface of the current collector on which the shielding film is not attached, and primarily drying same; (iv) removing the shielding film from the temporary electrode; and (v) manufacturing an electrode by secondarily drying the temporary electrode.
