METHOD FOR MANUFACTURING ELECTRODE ASSEMBLY

A method of manufacturing a stackable-foldable electrode assembly utilizing a negative electrode structure having a negative electrode comprising a lithium metal layer interposed between two separating films is provided. The method includes the steps of positioning a lithium metal layer to protrude in the width direction between two separating films, manufacturing a negative electrode structure by joining the lithium metal layer and the separating films, laminating one positive electrode on the negative electrode structure, folding the negative electrode structure in the width direction to enclose the positive electrode, repeating the previous steps to manufacture an electrode laminate comprising a plurality of positive electrodes, cutting a portion of the lithium metal layer protruding in the width direction to form negative electrode tabs, and joining the negative electrode tabs. The method of manufacturing an electrode assembly may minimize processing of the lithium metal, thereby improving the productivity of the electrode assembly.
