Abstract
The present invention discloses a method of manufacturing an electrode for a secondary battery by using a single process to notch and cut a unit electrode from an electrode sheet. The method for manufacturing electrodes for a secondary battery includes supplying an electrode sheet in a moving direction (MD), wherein the electrode sheet has a plurality of coated portions and uncoated portions alternately arranged along the MD, wherein each coated portion has an electrode active material, and each uncoated portion does not have an electrode active material; and cutting the uncoated portions to form the plurality of unit electrodes.
