Abstract:
The present invention relates to a method of manufacturing an electrode for a rechargeable battery, including (a) coating electrode slurry including an electrode active material, a binder, and a solvent on one surface of a sheet-shaped current collector; and (b) drying the electrode slurry while applying vacuum in a direction of decreasing agglomeration of the binder due to vaporization of the solvent.
