Title:
MANUFACTURING SYSTEM AND METHOD FOR DRY ELECTRODE FILM
Document Type and Number:
WIPO Patent Application WO/2023/014126
Kind Code:
A1
Abstract:
A dry electrode film manufactured according to a manufacturing method of the present invention has even and uniform edges, and thus the width of the dry electrode film may be consistently controlled so as to be a predetermined width. In addition, if a roll-to-roll continuous process is applied when manufacturing the dry electrode film, the width of the dry electrode film may be uniformly controlled during the manufacturing. In addition, since the width of the dry electrode film is easily controllable, even if the dry electrode film is manufactured through different production batches, variations in the widths of the dry electrode film among batches may be minimized. In addition, since the edge borders of the dry electrode film are uniform and consistent, the damage rate of the dry electrode film caused by cracking, etc. is very low, and the dry electrode film may be easily handled.
