Abstract
A method of manufacturing a pouch-shaped battery cell including a silicon-based negative electrode active material includes injecting an electrolytic solution into a pouch-shaped battery case, in which an electrode assembly is mounted, charging and discharging the pouch-shaped battery cell having the electrolytic solution injected thereinto (a primary formation step), 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 while pressure is applied to the pouch-shaped battery cell by the jig (a jig grading step).
