Abstract
A notching apparatus for an electrode substrate of a rechargeable battery is provided. The notching apparatus includes: a lower plate assembly including a die; an upper plate assembly including a punch facing toward the die; and a pusher on a first side of the punch and the die in a second direction. The pusher is configured to notch an electrode from an electrode substrate passing between the lower plate assembly and the upper plate assembly in a first direction and to separate scrap generated during the notching by pressing with a blade. The blade connects an exterior and an interior of the die in the second direction, and at least one of a first side of the punch and the die have a recess configured to accommodate the blade.
