Abstract

The present disclosure relates to a magnetic alignment device and a method of magnetic alignment of electrode active material in electrode using the same. The magnetic alignment device has a structure that controls the directionality of the N poles and S poles of each of a plurality of unit magnets included in a first magnetic portion and a second magnetic portion to magnetize magnetic members positioned between the unit magnets, and applies a magnetic field to electrode slurry through the magnetized magnetic members. Therefore, the magnetic alignment device can perform magnetic alignment of electrode active material in an electrode with high efficiency during manufacturing of electrodes for lithium secondary batteries. In addition, as the magnetic alignment device can easily control the application of a magnetic field depending on the magnetization of the magnetic members, it has the advantages of excellent workability and high economic efficiency in electrode manufacturing.
