PURPOSE: A manufacturing method of an electrode assembly is able to improve the capacity and quality of a battery compared to the identical standard battery while improving the manufacturing process of a battery cell by improving the production speed of a battery. CONSTITUTION: A manufacturing method of an electrode assembly (400) with a structure in which more than two unit cells are laminated comprises (i) a process of preparing a unit cell (a) in which an electrode plate is positioned on both external sides, respectively, and a unit cell (b) in which a membrane is adhered to both external sides, respectively; (ii) a process of laminating the unit cells on a unit cell laminating part so that an anode and a cathode face each other; (iii) a process of surrounding the exterior of the unit cell laminate taken from the unit cell laminating part with a film (410); and (iv) a process of thermally contracting the film surrounding the exterior of the unit cell laminate. |
