Abstract
A method of manufacturing a pouch-shaped battery cell includes injecting an electrolytic solution into a pouch-shaped battery case, in which an electrode assembly is received, placing the pouch-shaped battery cell in a jig configured to fix and press the pouch-shaped battery cell and charging and discharging the pouch-shaped battery cell in the state in which pressure is applied to the jig (an activation step).
