Abstract: Disclosed are an electrode assembly manufacturing method including sequentially stacking a first electrode, a separator, and a second electrode on a separation film having a continuous length to form mono-cells, each of the first electrode, the separator, and the second electrode being cut to a predetermined size from a winding roll so as to have a discontinuous structure, bonding the stacked mono-cells using a lamination device, locating a bi-cell at a folding start part, from which folding starts, on the separation film so as to be spaced apart from the mono-cells by a distance for folding, and performing folding in one direction with the bi-cell as a beginning, whereby it is possible to immediately perform the folding process without a separate preparation process after the lamination process in order to simplify the electrode assembly production process, and an electrode assembly manufactured by the method.

Abstract: Discussed is an apparatus for notching an electrode sheet for an electrode tab, the apparatus including: a transfer unit including first and second transfer rollers to continuously, transfer the electrode sheet at regular intervals; a jig unit disposed between the first and second transfer rollers, and supporting a non-coating portion of the electrode sheet; and a notching unit to notch the non-coating portion supported on the jig unit, wherein the jig unit includes: a rotation member provided between the first and second transfer rollers and rotated in a direction perpendicular to a transfer direction of the electrode sheet; and two or more jigs to support the non-coating portion disposed between the first and second transfer rollers, and the jig unit is able to improve a supporting force of the electrode sheet, to prevent the electrode sheet from vibrating, and accurately notch an electrode tab to the electrode sheet.
