Title:
METHOD FOR MANUFACTURING BATTERY ELECTRODE PLATE
Document Type and Number:
WIPO Patent Application WO/2006/109594
Kind Code:
A1
Abstract:
A method for manufacturing a battery electrode plate is provided with a step of intermittently transferring a strip-shaped electrode plate material (1) in a length direction by a prescribed quantity to be aligned and stopping the material; and a step of compacting the electrode plate material (1) by pressing a cutting section of the material from the top and the bottom, between an upper stripper (12) and an upper cutting metal die (11) sliding each other, and a lower stripper (14) and a lower cutting metal die (13) sliding each other, and cutting the compacted section by sliding cutting blade sections (11a, 13a) of the upper and lower cutting metal dies (11, 13) each other. Thus, the electrode plate material is cut while suppressing generation of a large burr, which causes short-circuit failure between the electrode plates, without deteriorating productivity nor increasing cost, and the battery electrode plate is obtained.
