Title:
SECONDARY BATTERY ELECTRODE SLURRY COATING DEVICE, AND ELECTRODE SLURRY COATING METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/027505
Kind Code:
A1
Abstract:
The present invention pertains to a secondary battery electrode slurry coating device and an electrode slurry coating method. The electrode slurry coating device comprises a slurry transfer pipe having a dual structure including first and second pipes. Thus, when transferring an electrode slurry stored in a slurry tank to a slot die, the temperature of the electrode slurry can be kept constant. Accordingly, the electrode slurry can be uniformly applied to a current collector to reduce the rate of defects in the electrode manufacturing process.
