Document Type and Number:

WIPO Patent Application WO/2018/052213

Kind Code:

A1

Abstract:

In order to solve the problem with a polymer binder non-uniformly dispersed in an electrode active material layer and improve the adhesive strength between an electrode current collector and an electrode active material layer, the present invention provides a method for manufacturing an electrode, comprising the steps of: (S1) applying, on one surface of an electrode current collector, an electrode slurry obtained by dispersing an electrode active material, a polymer binder, and a conductive material in a solvent; (S2) laminating a polymer film on the upper surface of the electrode current collector on which the electrode slurry is applied; (S3) drying the electrode current collector having the polymer film laminated thereon to evaporate the solvent; and (S4) rolling the electrode current collector having the polymer film laminated thereon to produce an electrode.
