System and method for manufacturing cell stack of secondary battery

Disclosed are a system and method for manufacturing a cell stack of a secondary battery. Thus,a separation membrane can be supplied to a stacking table that reciprocates left and right, and electrodeplates (positive and negative plates) are alternately transferred on both sides of the stacking table, and the separation membrane is folded into a zigzag while a positive plate and a negative plate are stacked in the established order to make the battery cell stack. The system comprises a stacking table, which is installed to move horizontally back and forth with the help of a linear motion device, a separation membrane supply part, which supplies a separation membrane to the stacking table; a positive electrode supply part, which is arranged on one side of the stacking table; a negative electrode supply part, which is arranged on the other side of the stacking table, supplies and stacks negative plates to the separation membrane on the stacking table; and a separation membrane guide unitwhich is arranged on the
