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.
