WIPO Patent Application WO/2023/085829

Kind Code:

A1

Abstract:

The present invention discloses a cutting device, an electrode assembly, a battery cell, an electrode assembly processing device, a battery pack and a vehicle comprising same, and a method for manufacturing the battery cell. The present invention provides a cutting device comprising: a first cutter portion (210) which forms a first cutting line (113) in an axial direction on the uncoated portion (15) extending in the axial direction, while moving in the axial direction of the electrode assembly (110), and separates a scheduled cutting portion (115a) and a scheduled forming portion (117a) on the basis of the first cutting line (113); and a second cutter portion (220) which forms a second cutting line (16a) in the circumferential direction with respect to the uncoated portion (15) wound in the circumferential direction, while moving in the radial direction of the electrode assembly (110), and forms a cut surface portion (115) in the uncoated portion (15) of the electrode assembly (110) by making the second cutting line (16a) be connected to the first cutting line (113) and thus cutting an outer portion (117b) of the scheduled forming portion (117a) and the scheduled cutting portion (115a) surrounded by the first cutting line (113) and the second cutting line (16a).
