Title:
MAGNETISM ALIGNMENT APPARATUS FOR NEGATIVE ELECTRODES AND METHOD FOR MANUFACTURING NEGATIVE ELECTRODES USING SAME
Document Type and Number:
WIPO Patent Application WO/2024/058539
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 strength of the magnetic field can be easily controlled by measuring, in real time, the degree of alignment of a negative electrode active layer that has been dried with carbon-based negative electrode active material in a state of magnetic alignment, and individually controlling the distance separating unit magnets in the array of magnets of a magnet part according to the measured degree of alignment of the carbon-based negative electrode active material. Therefore, the degree of alignment and uniformity are high in the crystal surface of the carbon-based negative electrode active material.
