An packing apparatus for an automated manufacturing system of a secondary lithium battery is disclosed. The packing apparatus comprises: a frame; a base member which is installed at the frame, and is provided with a receiving rack for receiving a batch of separator both surfaces of which are laminated with positive electrode plates and negative electrode plates in a predetermined pattern; a stopper member installed at the frame to be linearly movable so as to selectively approach one end of the base member for preventing the separator being supplied to the base member from being separated from the receiving rack; a folder member installed at the frame to be linearly movable with respect to the receiving rack so that the folder can press the separator supplied to a receiving space formed by the receiving rack and the stopper member for predetermined duration, and fold the separator so that both side sections of the folded separator can have the shape of "Z", and the positive electrode plates and the negative electrode plates can alternate with each other; and a cutting/taping member for moving the separator folded in the shape of "Z" to a predetermined area, cutting the separator at a non-electrode plate area to which no electrode plate is attached, and taping the folded and cut piece of separator.
