主权项 1. An electrode assembly configured to have a structure in which one bi-cell and at least one monocell are folded in a state in which the bi-cell and the monocell are arranged on a continuous separation film, the bi-cell is a unit cell configured to have a structure in which at least one cathode and at least one anode are stacked in a state in which a separator is disposed between the cathode and the anode, types of the electrodes located at opposite surfaces of the bi-cell are the same, and the bi-cell is placed on a folding start region of the separation film, the monocell is a unit cell configured to have a structure in which at least one cathode and at least one anode are stacked in a state in which a separator is disposed between the cathode and the anode, types of the electrodes located at opposite surfaces of the monocell are different from each other, the monocell has a length equivalent to n times (where, n being an integer equal to or greater than 2) a width w of the bi-cell, and the monocell is arranged at a position at which the monocell is spaced apart from the bi-cell by a length equivalent to the width w of the bi-cell such that an electrode of the monocell opposite to the electrodes of the bi-cell at the opposite surfaces of the bi-cell faces upward, and the monocell is bent by a unit length equivalent to the width w of the bi-cell in the folded state.
