Title:
電池用極板群及びその製造方法
Document Type and Number:
Japanese Patent JP4971537
Kind Code:
B2
Abstract:
A rectangular electrode plate (1) including a core metal sheet and a mixture paste coated thereon has a lead (2) on one long side edge thereof where no mixture is coated, and a mixture non-coated part (4) on the other side edge thereof. Positioning holes (5a, 5b) are punched only in the lead so that the stress exerted when punching the holes will not cause the mixture paste to fall off. Stacked electrode plates are accommodated within a magazine (22A) with a certain clearance (28) between the three side edges of the electrodes other than the lead and the inner surface of the magazine, and fed one by one to be assembled into an electrode plate group to form a battery.
