Provided are a stack-and-fold type electrode assembly enhanced with cell cycle properties by evenly immersing electrolytes inside the unit cell, and a method for manufacturing the same. The stack-and-fold type electrode assembly according to the present invention has multiple laminated unit cells, which are overlapped, and a continuous folding separation film sheet is interposed at each overlapping portion. Porous tubes are sandwiched between the folding separation sheet which is covered by winding the overlapped unit cells and sides of the unit cells. According to the present invention, since electrolytes are evenly immersed inside the unit cells, the battery cycle properties can be improved, and gasified electrolytes or gases generated inside the electrode assembly can be easily emitted. |
