Abstract
The present invention relates to a dual slot die and a coating method using the same, wherein there is the advantage that electrode slurry coating and insulating solution coating simultaneously proceed through a dual slot die to prevent the occurrence of electrode slurry sliding at the edge of the electrode slurry layer. An electrode slurry layer and an insulating layer can be formed on a current collector sheet in a multi-line manner by including a shim having a structure formed with multiple discharge lines capable of discharging the electrode slurry or insulating solution in multiple lines, thereby increasing process efficiency.
