PURPOSE: A method for manufacturing a multilayer lithium secondary battery is provided to perform attachment of electrode plates simply by using a small-sized device, thereby being capable of producing the battery having improved cycle life and charge/discharge performance without the risk of electrical short. CONSTITUTION: The method comprises the steps of: (a) attaching a plurality of first electrode plates(100a) adjacent to each other onto one side of a separator(200) in odd row; (b) attaching a plurality of second electrode plates(100b) adjacent to each other onto the opposite side of separator(200) in even row; (c) folding the separator(200) in a zigzag pattern so that electrode plates in multiple rows are overlapped and then folding the separator along a line between plates sequentially in one direction to obtain a laminate(400); and (d) injecting an electrolytic solution and packing. In the laminate, separator is disposed between the first electrode plates and the second electrode plates opposed to each other alternatively, and taps of the anode plates are piled on one another and taps of the cathode plates are piled on one another. |
