Abstract:
The present invention provides a fabrication method of a multilayer electrode for a secondary battery including: (a) preparing two or more electrode slurries each containing an electrode active material, a binder, and a solvent and heating at least one electrode slurry selected from the prepared two or more electrode slurries to a temperature lower than a boiling point (Tb) of the solvent contained in the selected electrode slurry; (b) coating the two or more electrode slurries on a current collector; and (c) cooling the coated two or more electrode slurries.
