Apparatus and method for coating electrode

An electrode coating apparatus comprising:

• a die coater configured to apply an electrode slurry onto a substrate;
• an injection port configured to receive supply of the electrode slurry therethrough to the die coater;
• a flow path having an end coupled to the injection port and configured to receive movement therethrough of the electrode slurry to the die coater;
• and
• a turbulent flow generator provided within the flow path and configured to generate a turbulent flow in the electrode slurry within the flow path,
• wherein the turbulent flow generator has a cross-section pattern having a plurality of polygons disposed adjacent to one another in a direction perpendicular to a longitudinal direction of the flow path, the cross-section pattern comprising ten or less closed polygon figures that maintain a repeated polygon shape, and
• wherein the turbulent flow generator comprises plates that form the plurality of polygons, the plates extending parallel to the longitudinal direction of the flow path.
