Double Slot Die For Simultaneously Performing Electrode Slurry Coating

Double Slot Die For Simultaneously Performing Electrode Slurry Coating And Insulating Liquid Coating, And Coating Method Using Same

Abstract: The present invention relates to a double slot die and a coating method using same. The present invention has the advantages of electrode slurry coating and insulating liquid coating being simultaneously performed by means of a double slot die, thereby preventing the occurrence of sliding of an electrode slurry at an edge of an electrode slurry layer, and of comprising a shim having a structure in which multiple discharge lines are formed that can divide and discharge electrode slurry or insulating liquid into several lines such that an electrode slurry layer and an insulating layer can be formed in multiple lines on a current collector sheet, thereby increasing processing efficiency.
