Abstract
A method of detecting a lamination defect of an electrode assembly in the initial stage, including: forming an insulating member having a predetermined width and a predetermined height in an overhang region of one end or two ends of one surface of a negative electrode; manufacturing an electrode assembly by sequentially laminating a separator and a positive electrode on one surface of the negative electrode; and determining whether there is a lamination defect in the electrode assembly by measuring a thickness of the electrode assembly. Also provided are an electrode assembly including an insulating member, and a battery cell including the electrode assembly.
