Abstract

Disclosed herein relates to a dual layer slot die coater including: a first die block equipped with a first manifold for accommodating an electrode slurry; a middle block coupled to the first die block; a first coater shim that forms a first electrode slurry slot for discharging an electrode slurry filled in the first manifold, which is interposed between the first die block and the middle block in a shape that wraps around both sides and a rear surface of the first manifold; a second die block that is coupled to the middle block and equipped with a second manifold for accommodating an electrode slurry; and a second coater shim that forms a second electrode slurry slot for discharging an electrode slurry filled in the second manifold, which is interposed between the second die block and the middle block in a shape that wraps around both sides and the rear surface of the second manifold, wherein the first coater shim and the second coater shim each include a first insulating solution flow path and a second insulating solution flow path forming a first insulating solution slot and a second insulating solution slot for discharging insulating solution, respectively, wherein an insulating solution supply flow path for supplying insulating solution to the first insulating solution flow path and the second insulating solution flow path is formed by penetrating the middle block.
