Abstract

A magnetic alignment device for negative electrode and method for manufacturing negative electrode using the same. The magnetic alignment device can measure the loading amount of the negative electrode slurry applied on the negative electrode collector in real time and can easily control the intensity of the magnetic field by adjusting the separation distance of the magnet portion according to the measured negative electrode slurry loading amount, and has an advantage of uniformly high alignment degree of the crystal faces of the carbon-based negative electrode active material contained in prepared negative electrode active layer.
