Abstract

The present disclosure relates to an apparatus and a method for manufacturing a battery cell, and more particularly, to an apparatus and a method for manufacturing a battery cell, wherein a pressing jig provided with a semi-elliptical pressing part presses the battery cell to remove air bubbles from the battery cell.

Claims (6)

1. An apparatus for manufacturing a battery cell to remove air bubbles from the battery cell, the apparatus comprising:

a pair of pressing jigs each having a semi-elliptical pressing part made of a flexible, elastic material formed on a contact surface contacting the battery cell and configured to apply a pressure to upper and lower portions of the battery cell, the pressure being applied sequentially from a central portion of the battery cell to first and second peripheral portions so as to displace the air bubbles to the first and second peripheral portions, wherein the first and second peripheral portions are located on opposite sides of the battery cell; and

a support part configured to fix the battery cell between the pair of pressing jigs,

wherein the pressure is applied to the pair of pressing jigs to discharge the air bubbles from the first and second peripheral portions to outside of the battery cell.

2. The apparatus of claim 1 , wherein each of the pair of pressing jigs is larger than the battery cell.

3. The apparatus of claim 1 , wherein the pair of pressing jigs discharge the air bubbles by further applying a predetermined amount of heat when pressing the battery cell.
