摘要 |
The present invention relates to an electrode assembly comprising at least two unit cells, which comprise a positive electrode, a negative electrode, a separation membrane inserted between the positive electrode and the negative electrode, and an electrode tap projected out from each electrode. Each of the unit cells has a folded, stacked, folded-and-stacked, or laminated-and-stacked electrode structure, and at least two of the unit cells have different electrode structures. The unit cells are arranged in layers in a height direction with respect to a plane, and a separation membrane or a separation film is inserted between the unit cells. |
