  • Publication number: 20230099713
    Abstract: Disclosed is a method for manufacturing a dry electrode. In the method, a conductive primer layer and an insulating protective layer are formed in a single step, or the insulating protective layer is formed first before an electrode active material layer is formed and after the conductive primer layer is formed. In this manner, there is no gap between the insulating protective layer and the conductive primer layer, thereby providing further improved insulation property. In addition, since the dry electrode is manufactured by laminating the current collector having the conductive primer layer and the insulating protective layer with the dry electrode film, an electrode having excellent adhesion and improved stability can be obtained advantageously.
