Abstract: 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.

Abstract: The occurrence of separation or reaggregation is suppressed in a suspension such as a battery electrode slurry. A battery electrode slurry distributing apparatus includes: a circulation pipe via which a positive electrode slurry is to be circulated; and a control unit that controls the supply of the positive electrode slurry to each of coaters. In a period in which either the coater is allowed to receive the supply of the positive electrode slurry, the control unit inhibits the supply of the positive electrode slurry to the other coater. The circulation pipe is structured in a polygonal loop. The coaters are connected to respective elbow portions formed in the circulation pipe via the pipes, respectively.

Abstract: A secondary battery manufacturing method enables smooth pulling of a separator by guide members by inhibiting a phenomenon in which, when the separator is being pulled by the guide members, the separator moves in the width direction and rattles. The method includes pulling in a separator by guide bars to zigzag-fold the separator; and suspending the separator between the guide bars via a suspension roller while locating buffer rollers at a predetermined descending position, the buffer rollers being disposed between support rollers for supporting the separator at midpoints upstream, in the transport direction of the separator, of the suspension roller, the buffer rollers being ascendable and descendable in contact with an upper surface of the separator to be adjustable vertically, and allowing the buffer rollers to ascend in accordance with movement of the guide bars, thereby supplying the separator of a length pulled in by the guide bars.
