Abstract
A method for preparing an electrode for a secondary battery, includes preparing an electrode slurry having an electrode active material and a binder and producing a pre-electrode by coating a first surface of both surfaces of a current collector with the electrode slurry while the first surface is disposed in an upward direction. Additionally, the method includes drying the pre-electrode while the electrode slurry coated on the first surface of the current collector is inverted to be disposed in a downward direction.
