  • Publication number: 20230114069
    Abstract: Disclosed is a method for manufacturing a dry electrode. The method includes buffing the surface of a pre-electrode film formed in a sheet-like shape to remove the surface waviness in the manufacture of an electrode film, and then carrying out a calendering process, thereby ensuring the uniformity of the electrode film thickness and electrode active material density in the electrode film. In other words, it is possible to minimize a deviation in loading amount, porosity and thickness of the electrode depending on the location, and thus to provide improved overall electrochemical performance, including improved battery life characteristics.

  • 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.
