Abstract: A slot die coater includes a lower die block including a first manifold in which an electrode active material slurry is accommodated, an upper die block including a second manifold in which an insulating coating solution is accommodated, and a shim plate located between the lower die block and the upper die block to form a slot communicating with a discharge port. The shim plate includes a first concave portion provided in a first surface located to cover the first manifold of the lower die block, and a second concave portion provided in a second surface located to cover the second manifold of the upper die block, wherein two second concave portions are configured to be located on opposite sides of the first concave portion in a width direction.

Abstract: A slot die coater is configured for making a coating width of a multi lane model uniform and reducing a condition adjustment loss in the subsequent production. The slot die coater includes an upper plate; a lower plate; and shims interposed between the upper plate and the lower plate and defining at least two individual lanes to form a slot. The shims defining the individual lanes include a fixing pin to improve positional precision when fixing to the upper plate or the lower plate and a fixing bolt for fixing to the upper plate or the lower plate.
