Abstract:
Provided is a method of manufacturing a laminated secondary battery in which in the battery cell laminate in which the electrode cells are laminated, one full cell manufactured by the heat fusion process is laminated, and each unit electrode cell is laminated between each of the full cells to form one electrode assembly, thereby simplifying a manufacturing process, minimizing reworking due to defective electrode cells and minimizing an initial investment cost. To this end, provided is a method of manufacturing a laminated secondary battery having a structure in which two or more unit cells (a), an electrode cell (b), and an electrode cell (c) are cross stacked, including: 1) preparing a unit full cell, wherein the unit cell (a) is composed of a separation membrane/a cathode cell/a separation membrane/a anode cell/a separation membrane; 2) preparing an anode unit cell by the electrode cell (b) and a cathode unit cell by the electrode cell (c); and 3) sequentially laminating the unit cell (a), the electrode cell (b), the flipped-over unit cell (a′), and the electrode cell (c), wherein the laminated uppermost electrode has a structure in which electrodes having the same polarity as the lowermost polarity of the unit cell (a) are laminated, and wherein the laminate completed with the lamination is wrapped with the outer film, and the film end portion is fixed by the tape or the heat fusion.

Claim (Index 1):
A method of manufacturing a laminated secondary battery having a structure in which a first unit cell (a), a second unit cell (a\u2032), an anode electrode cell (b), and a cathode electrode cell (c) are stacked, the method comprising:\n preparing the first unit cell (a) comprised of a separation membrane, a cathode, a separation membrane, an anode, and a separation membrane stacked from bottom to top; preparing the second unit cell (a\u2032) comprised of a separation membrane, an anode, a separation membrane, a cathode, and a separation membrane stacked from bottom to top in the reverse order of the first unit cell (a); preparing the anode electrode cell (b) formed of an electrochemical device including an anode collector on both sides of which an anode material is coated; preparing the cathode electrode cell (c) formed of an electrochemical device including a cathode collector on both sides of which a cathode material is coated; sequentially stacking the first unit cell (a), the cathode electrode cell (c), the second unit cell (a\u2032), the anode electrode cell (b), in the order from bottom to top; and repeating the sequential stacking, wherein an uppermost electrode of the stacked first unit cell (a) has a the same polarity as a lowermost electrode of the stacked second unit cell (a\u2032), wherein depending on a number of stacked electrodes, the first electrode cell (b) or the second electrode cell (c) is additionally stacked on the stacked structure, and an uppermost electrode of the stacked structure has the same polarity as a lowermost electrode of the stacked structure, and a separation membrane is disposed on the uppermost electrode of the stacked structure, wherein the completed stacked structure is wrapped with an outer film, and end portions of the outer film are fixed to each other by a tape or a heat fusion.
