Abstract
A pressing jig of a battery cell including a pressing pad, in which the modulus of the central region is different from the modulus of the peripheral region, and a method of degassing a battery cell using the same are provided. The pressing pad can easily discharge gas in the battery cell during the formation process of a battery cell by allowing higher pressure to be applied to the central region than the peripheral region.
