    Abstract: A magnetic alignment device applies a magnetic field to a negative electrode slurry by introducing a magnet part to an upper and a lower portion of a negative electrode current collector on which the negative electrode slurry is applied, respectively. By applying a stronger magnetic field in a second region of the magnet part located downstream along the transfer direction of the negative electrode current collector than in a first region of the magnet part located upstream, and by arranging a drying part adjacent to the end of the second region where the stronger magnetic field is applied, a negative electrode having a significantly higher alignment of the carbon-based negative electrode active material contained in the negative electrode slurry can be manufactured. A method for manufacturing a negative electrode using the magnetic alignment device is also provided.

    Abstract: An electrode manufacturing apparatus includes a support roll supporting an electrode sheet, at least one pressure roll, a level sensor, and a control unit. The electrode sheet includes a coated portion and an uncoated portion, and the support roll transports the electrode sheet in a first direction. The pressure roll contacts the support roll with the electrode sheet disposed therebetween and pressurizes the uncoated portion of the electrode sheet. The level sensor detects a level of the uncoated portion, and the control unit controls the pressure roll in response to the level detected by the level sensor. The at least one pressure roll is movable in a second direction crossing the first direction.

    Abstract: A die coater capable of simultaneously coating a current collector with two different liquids in multiple layers, includes a first body with a first manifold for an electrode slurry, a second body with a second manifold coupled to the first body to form a first slit through which the electrode slurry in the first manifold is discharged, and a third body coupled to the second body to form a second slit through which the electrode slurry in the second manifold is discharged. The first slit is formed by a first and third shim that are interposed between coupling surfaces of the first and second body, and the second slit is formed by a second and fourth shim that are interposed between coupling surfaces of the second and third body, and at least any one of the third shim and the fourth shim forms an insulating liquid slit.
