Abstract

A method for manufacturing a battery cell for evaluating a lithium precipitation behavior includes: an electrode assembly preparation step of preparing an electrode assembly to which an overhang region, where a positive electrode protrudes from a negative electrode, is introduced; a battery cell preparation step of preparing a battery cell by accommodating the electrode assembly in a first pouch, injecting an electrolyte solution thereto, and sealing the first pouch; a secondary sealing step of accommodating the battery cell in a second pouch and secondary-sealing the second pouch; a second pouch removing step of performing formation for the secondary-sealed battery cell and removing the second pouch; a gas pocket unit removing step of degassing and re-sealing the battery cell, from which the second pouch has been removed, and removing a gas pocket unit of the first pouch; and a completion step of accommodating the battery cell.
