A die coater capable of simultaneously
coating a
current collector with two different liquids in multiple
layers includes a first body with a first manifold for an
electrode slurry, a second body with a second manifold coupled to the first body to form a first slit through which the
electrode slurry in the first manifold is discharged, and a
third body coupled to the second body to form a second slit through which the
electrode slurry in the second manifold is discharged. The first slit is formed by a first and third shim that are interposed between
coupling surfaces of the first and second body, and the second slit is formed by a second and fourth shim that are interposed between
coupling surfaces of the second and
third body, and at least any one of the third shim and the fourth shim forms an insulating liquid slit.
