Abstract: Provided is an ultra large-width coating device applied to a consecutive process. More particularly, the present invention relates to a coating device capable of maximizing productivity by consecutively manufacturing a large-width film without reducing physical properties of the manufactured film by overcoming a problem in that a coating width is limited during a coating process using the existing contact type coating roller, and a method for manufacturing an ultra large-width membrane using the same.

Abstract: A sealing device for a pouch-type battery includes an upper sealing block and a lower sealing block. The upper sealing block has a two-stage upper sealing groove, including a first upper step and a second upper step, and the lower sealing block has a two-stage lower sealing groove, including a first lower step and a second lower step. The upper sealing block contacts a first surface of an electrode lead sealing part of the pouch-type battery, and the lower sealing block contacts a second surface of the electrode lead sealing part of the pouch-type battery in a process of performing sealing through heat fusion. A pouch-type battery having an electrode lead sealing part formed by the sealing device is also provided.
