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).
Claims9
A method of manufacturing a pouch-shaped battery cell, the method comprising:
- 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
- an activation step including charging and discharging the pouch-shaped battery cell while pressure is applied to the pouch-shaped battery cell by the jig such that the pouch-shaped battery cell has a state of charge (SOC) of 50% to 100%.
