PURPOSE: Provided is a method for manufacturing a multilayer lithium secondary battery with improved charge/discharge characteristics and reduced electrical short by performing simple attachment process with a small-sized device. CONSTITUTION: The method comprises the steps of: (a) attaching a plurality of first electrode plates(100a) adjacent to each other onto a part of one side of a separator(200); (b) folding the unattached part of the separator(200) to cover the electrode plates(100a); (c) attaching a plurality of second electrode plates(100b) adjacent to each other onto the folded part in the same direction as the attached first electrode plates(100a); (d) folding the separator(200) along a line between plates sequentially in one direction to obtain a laminate; and (e) injecting and packing. In the laminate, connected two films of separator have a pattern folded in one direction from the inside to the outside to be disposed between the first electrode plates and the second electrode plates opposed each other, and taps of the first electrode plates are piled on one another and taps of the second electrode plates are piled on one another. |
