Title:
MAGNETIC ALIGNMENT DEVICE FOR ANODE, AND ANODE MANUFACTURING METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2024/080618
Kind Code:
A1
Abstract:
The present invention relates to a magnetic alignment device for an anode, and an anode manufacturing method using same. The magnetic alignment device introduces magnetic units to each of the upper part and the lower part of an anode current collector to which an anode slurry is applied, so as to apply a magnetic field to the anode slurry, and a magnetic field stronger than that of a first area of a magnetic unit positioned upstream is applied to a second area of a magnetic unit positioned downstream in the transfer direction of the anode current collector, and a drying unit is arranged to be adjacent to the end of the second area to which the stronger magnetic field is applied, and thus an anode having a remarkably high degree of alignment of a carbon-based anode active material contained in the anode slurry can be manufactured.
