Abstract:
1. A method of manufacturing a rectangular battery, comprising the steps of: arranging a plurality of guide members in zigzag form in a perpendicular direction; inserting a continuous member of a separator having a first surface and an opposite facing second surface between rows of the guide members; folding, into a zigzag form, the continuous member by intersecting the rows of the guide members in a horizontal direction; inserting, alternately, positive electrodes and negative electrodes in respective valley grooves of the zigzag-folded continuous member such that the positive electrodes are inserted into first valley grooves formed in a first surface side of the separator in a state in which the guide members are preliminarily placed in the grooves on the first surface side, and such that the negative electrodes are inserted into second valley grooves formed in a second surface side of the separator in a state in which the guide members are preliminarily placed in the grooves on the second surface side; withdrawing the guide members from the respective valley grooves of the continuous member; and pressing, thereafter, the continuous member in the zigzag direction so as to make flat the continuous member.
