Electrode Assembly and Method for Manufacturing Same

Abstract

A manufacturing method according to the present invention is a method for manufacturing an electrode assembly in which a negative electrode, a separator, and a positive electrode are repeatedly stacked, the method comprising: a unit cell manufacturing step of manufacturing a unit cell having a predetermined stack structure of the negative electrode, the separator, and the positive electrode, wherein ends of the separators are bonded to each other to form a bonding portion; a film inserting step of inserting a film into a die; a unit cell stacking step of stacking the unit cell into the die; and a thermal fusing step of applying heat and a pressure to thermally fuse the film to the bonding portion of the stacked unit cell within the die. An electrode assembly assembled according to the manufacturing method is also disclosed.
