Member for slot die coater, movable member for slot die coater, and slot die coater including the members to produce electrode

摘要

Provided is a slot die coater that applies electrode slurry to metal foil to produce an electrode, the slot die coater including a die part, which includes a body having an inner space receiving the electrode slurry, a supply hole disposed in the body to supply the electrode slurry to the inner space, and a discharge hole disposed in the body to discharge the electrode slurry from the inner space to the metal foil, and a member for the slot die coater, which is removably installed in the inner space to form a slope surface in the inner space, or a movable member for the slot die coater, which selectively forms the slope surface.

1. A slot die coater that applies electrode slurry to metal foil to produce an electrode, the slot die coater comprising:
a die part, which includes a body having an inner space receiving the electrode slurry, a supply hole disposed in the body to supply the electrode slurry to the inner space, and a discharge hole disposed in the body to discharge the electrode slurry from the inner space to the metal foil; and a member for the slot die coater, which is removably installed in the inner space to form a slope surface in the inner space, wherein the inner space has a first side surface provided with the discharge hole, a second side surface facing the first side surface, and a third side surface extending from the second side surface to the first side surface, and the slope surface is inclined from the second side surface to the third side surface, wherein the member is a movable member for the slot die coater, which is removably installed in the inner space to selectively form a slope surface in the inner space, wherein the movable member includes: a column member fixed to the body; and a back plate member, an end of which is rotatably coupled to the column member, and another end of which extends to the third side surface, and wherein the back plate member rotates about the column member to form the slope surface.
