MANUFACTURING METHOD OF AN ELECTRODE ASSEMBLY, AND MANUFACTURING APPARATUS OF AN ELECTRODE ASSEMBLY

A manufacturing method of an electrode assembly in which a positive electrode and a negative electrode are alternately stacked and a separator is positioned between the positive electrode and the negative electrode according to an embodiment of the present invention includes: a first step of disposing the positive electrode above a first separator; a second step of disposing a second separator above the positive electrode to cover the positive electrode; a third step of disposing a negative electrode above the second separator; and a fourth step of disposing a third separator above the negative electrode to cover the negative electrode. In the first step and the third step, a laser beam is irradiated to indicate positions at which the positive electrode and the negative electrode are disposed.
