OVERLAPPED ELECTROCHEMICAL CELL AND METHOD FOR PRODUCING THE SAME |
摘要 |
PURPOSE: An overlapped electrochemical cell is provided to increase capacity density of the cell, to improve spacial efficiency and to maximize content of electrode active material by overlapping a plurality of full cells and/or bicells. CONSTITUTION: The cell comprises as a constitutional unit the full cell(17) consisting of positive electrode(7) including positive current collector(12) and positive material(14), separation films(15) and negative electrode(8) including negative current collector(11) and negative material(13) in the overlapped structure by multiple full cells. Between each full cells, separation films are interposed. The separation film has a unit length to enclose the cell and is bent inward to continuously fold each cell in Z shape from the cell in the middle portion to the outermost portion therein so that it can be interposed between the cells. |
