ELECTRODE ASSEMBLY, BATTERY CELL, BATTERY CELL PROCESSING APPARATUS, AND BATTERY PACK AND VEHICLE INCLUDING SAME

The present invention discloses an electrode assembly, a battery cell, and a battery cell cutting device, and a battery pack and vehicle including the battery cell. The present invention provides an electrode assembly (110) including an electrode cell body portion (111) in which a separator (13) is stacked between a first electrode sheet (11) and a second electrode sheet (12) in the form of a sheet, the first electrode sheet (11), the second electrode sheet (12), and the separator (13) are wound in a jelly-roll type, and an uncoated portion (15), on which an active material layer is not coated, is formed in an end portion of each of the first electrode sheet (11) and the second electrode sheet (12) in a width direction, a plurality of cut surface portions (115) formed by cutting out a portion of the uncoated portion (15) along a circumferential direction around a core portion (112) of the electrode cell body portion (111), and a plurality of forming portions (117) that are disposed between the cut surface portions (115) and formed by pressing and laying down uncut portions (117a) of the uncoated portion (15).
