METHOD AND APPARATUS FOR MANUFACTURING ELECTRODE ASSEMBLY FOR RECTANGULAR BATTERY

摘要

In a method of manufacturing an electrode assembly for a rectangular battery, in which positive electrodes and negative electrodes are alternately laminated so that a separator exists between the respective positive and negative electrodes, the manufacturing method includes the steps of: arranging a plurality of guide members in zigzag form in a perpendicular direction; inserting a continuous member of the separator between one and another one rows of the guide members; folding, into zigzag form, the continuous member by intersecting the rows of the guide members in a horizontal direction; inserting alternately the positive electrodes and the negative electrodes in respective valley grooves of the zigzag-folded continuous member; 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.

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 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, and each of plurality of the positive electrodes inserted corresponding one of the first valley grooves concurrently with inserted another ones of the positive electrodes into corresponding another ones of the first valley grooves, and each of plurality of the negative electrodes inserted corresponding one of the second valley grooves concurrently with inserted another ones of the negative electrodes into corresponding another ones of the second valley grooves;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.
