Abstract

The invention discloses a coating device and a coating method using the same. The coating device comprises a coating roller which supports and delivers an electrode collector, a slit module which is disposed at one side of the coating roller for supplying slurry on the surface of the electrode collector, and an air curtain component which is disposed in an adjacent area adjacent to the slit module and the electrode collector so as to prevent slurry from falling down from the adjacent area.

Description

technical field [0001] Embodiments relate to a coating device and a coating method using the coating device. Background technique [0002] In a secondary battery, a slurry including an electrode active material is coated on the surface of an electrode collector formed of a metal foil or a metal mesh to manufacture an electrode plate. Generally, a slurry is formed by mixing a solvent, a plasticizer, an electrode active material, and a binder. [0003] In addition, the active material slurry is thinly coated on the electrode collector to form an electrode coating portion to manufacture electrode plates each having a large area and facing each other in a narrow space, and a separator is provided. A positive electrode plate, a separator, and a negative electrode plate are alternately stacked between two electrode plates having polarities different from each other and the positive electrode plate, separator, and negative electrode plate alternately stacked on each other are woun...
