1. A system for manufacturing a secondary battery, the system comprising: a positive electrode cell manufacturing line in which a positive electrode single cell, on which a positive electrode tab is processed on one end of a positive electrode and a first separator is combined on one surface of the positive electrode, is continuously manufactured, the positive electrode cell manufacturing line extending in a first direction along a first line; a negative electrode cell manufacturing line in which a negative electrode single cell, on which a negative electrode tab is processed on one end of a negative electrode and a second separator is combined on one surface of the negative electrode, is continuously manufactured, the negative electrode cell manufacturing line extending in the first direction along a second line spaced from and parallel to the first line; and a stacking part comprising a turn table rotatable towards both the first and second lines and configured to alternately receive a plurality of the positive electrode single cells and a plurality of the negative electrode single cells respectively from the positive electrode cell manufacturing line and the negative electrode cell manufacturing line to stack the plurality of the positive electrode single cells and the plurality of the negative electrode single cells up to a predetermined layer, thereby forming a stack cell, wherein the turn table of the stacking part is disposed between the first line of the positive electrode cell manufacturing line and the second line of the negative electrode cell manufacturing line to alternately rotate in both directions toward the terminal portion of the positive electrode cell manufacturing line and the terminal portion of the negative electrode cell manufacturing line, thereby alternately receiving the positive electrode single cell and the negative electrode single cell.
