Abstract:
Disclosed is a method for manufacturing a battery pack provided with multiple stacked unit cells. When a unit cell disposed on the outermost layer on one side is referred to as a first unit cell, and among a plurality of unit cells stacked in order from the first unit cell, the unit cell disposed on the outermost layer which is on the other side and faces the outermost layer on the one side is referred to as an Nth unit cell (where, N is an integer of 2 or more), the method comprises a step in which: an anvil is disposed on an external terminal of the Nth unit cell such that the anvil is on the outside of the battery pack; a transversely vibrating horn is disposed either on an external terminal of an N-1th unit cell such that the horn is on the outside of the battery pack, or between the external terminal of the N-1th unit cell and an external terminal of an N-2th unit cell; and the anvil and the horn are used to ultrasonically join the external terminal of the Nth unit cell and the external terminal of the N-1th unit cell.
