METHOD OF COATING A CURRENT COLLECTOR WITH A SLOT DIE COATER HAVING IMPROVED COATING SOLUTION FLOW

Provided is a slot die coater with a uniform flow of coating solution without stagnation. The slot die coater includes at least two die blocks; a shim plate provided between the two die blocks to form a slot; and a manifold provided in the die block and communicatively connected with the slot as a chamber in the shape of indention accommodating a coating solution, wherein the coating solution is discharged and applied to a surface of a continuously traveling substrate through a discharge port communicatively connected with the slot, and a ratio B/S of a manifold length B (mm) to a manifold cross-sectional area S (cm2) in a cross section along a traveling direction of the substrate is in a range of 1.9 to 9.8.
