摘要:
Disclosed herein is a method of locating a plurality of full cells constructed in a cathode/separator/anode structure, as basic units, on a separator sheet having a continuous length, further locating a unit electrode or a bi-cell on the separator sheet, and winding the full cells and unit electrode or the bi-cell to continuously manufacture a stacking/folding type electrode assembly constructed in a structure in which anodes are located at the outermost electrodes forming the outside of the electrode assembly, respectively, wherein the method including a step of continuously supplying a cathode sheet, an anode sheet, a first separator sheet, and a second separator sheet, to manufacture the unit cells, successively arranging the unit cells on the second separator sheet from a first stage to an nth stage, and winding the unit cells, a step of arranging cathode tabs and anode tabs at the respective stages, while the cathode tabs and the anode tabs are opposite to each other, and arranging electrode tabs having the same polarity between the neighboring stages, while the electrode tabs are opposite to each other, such that the electrode tabs having the same polarity are located all together at predetermined positions of the wound electrode assembly, and a step of supplying electrodes the number of which is odd from two electrode sheets and electrodes the number of which is even from one electrode sheet.
