Abstract
The present technology relates to an electrode slurry-discharging shim, and a coating die comprising same, the present technology allowing superbly even coating to be assured even when the electrode slurry coating is at a high load level. In one example, the present technology provides a coating shim for electrode slurry discharge according to the present invention having a step portion configured to be formed at an end of an electrode slurry discharge flow path and to increase a width of the discharge flow path, and the step portion is formed at opposite sides in a width direction of the electrode slurry discharge flow path.
Claims5
A coating shim for electrode slurry discharge, comprising:
- an open side in a discharge direction of the electrode slurry based on a cross-sectional structure of the coating shim;
- a guide portion formed at opposite sides of the coating shim and having a structure protruding in a width direction of the open side of the coating shim so as to decrease a width of an electrode slurry discharge flow path,
- wherein the guide portion has a shape in which a height protruding in the width direction of the discharge flow path increases continuously along the discharge direction from an upstream edge of the guide portion to reach a maximum height;
- a step portion formed vertically to an end of the electrode slurry discharge flow path so as to increase the width of the discharge flow path;
- and
- a horizontal portion connecting a downstream edge of the guide portion and the vertically formed step portion,
- wherein the step portion is formed at opposite sides in the width direction of the electrode slurry discharge flow path,
- wherein the width of the discharge flow path formed by the step portion at the end of the discharge flow path is in a range of 0.5 to 10% greater than a beginning width direction length of the discharge flow path.
