Title:
MAGNETISM ALIGNMENT APPARATUS FOR NEGATIVE ELECTRODES AND METHOD FOR MANUFACTURING NEGATIVE ELECTRODES USING SAME
Document Type and Number:
WIPO Patent Application WO/2024/058536
Kind Code:
A1
Abstract:
The present invention relates to a magnetism alignment apparatus used in manufacturing negative electrodes, and to a method for manufacturing negative electrodes using the magnetism alignment apparatus. The magnetism alignment apparatus can measure, in real time, the level of loading in the negative electrode slurry applied on the negative electrode current collector, and control the distance separating the magnet parts according to the level of loading of the negative electrode slurry to easily control the strength of the magnetic field. Therefore, the degree of alignment is uniformly high on the crystal surface of the carbon-based negative electrode active material contained in the manufactured negative electrode active layer.
