  • Publication number: 20240274780
    Abstract: Provided is a method for manufacturing a dry electrode film for an electrochemical device. The dry electrode film has a uniform and regular edge, and therefore can be controlled regularly to have a predetermined width. In addition, when using a roll-to-roll continuous manufacturing process, it is possible to control the width of the dry electrode film uniformly during the manufacture. Further, since it is easy to control the width of the dry electrode film, it is possible to minimize a difference in dry electrode film width between one manufacture batch and another manufacture batch, even when the dry electrode film is manufactured through different manufacture batches. Additionally, since the dry electrode film has a uniform and regular edge boundary, it is significantly less likely that the dry electrode film is damaged due to cracking or the like, and the dry electrode film can be handled with ease.
