Abstract
A method for manufacturing an electrode plate for a secondary battery, by performing a pattern-coating to have a coated part, on which an electrode slurry has been coated, and a non-coated part, on which the electrode slurry has not been coated, on an electrode current collector sheet, including: attaching at least one adhesive film on at least one portion of the non-coated part on the electrode current collector sheet; consecutively coating an electrode slurry on the electrode current collector sheet including the adhesive-film-attached portion; heating and drying the electrode slurry; and peeling the adhesive film from the electrode current collector sheet and retrieving the adhesive film.
Claims11
A method for manufacturing an electrode plate by performing a pattern-coating to have a coated part, on which an electrode slurry has been coated, and a non-coated part, on which the electrode slurry has not been coated, on an electrode current collector sheet, the method comprising:
- attaching at least one adhesive films on at least one portion of the non-coated part on the electrode current collector sheet;
- consecutively coating the electrode slurry on the electrode current collector sheet including the adhesive-film-attached parts;
- heating and drying the electrode slurry;
- and
- peeling the adhesive film from the electrode current collector sheet and retrieving the adhesive film, wherein an adhesive force of the adhesive film is reduced by the heating and drying of the electrode slurry, so that the adhesive film can be removed from the electrode current collector sheet during the peeling and retrieving, and as the adhesive film is removed, a surface of the electrode current collector sheet is exposed.
