Title:
電池用極板の製造方法
Document Type and Number:
Japanese Patent JP4473396
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent a transfer system failure due to variation in active material charged and warp by bonding one or more strip lead plates to a strip of three- dimensional porous metal and removing a warp in a substrate for a pole plate cut-formed later. SOLUTION: A strip lead plate 3 is bonded to a strip of three-dimensional porous metal and a portion near the lead plate is rolled between mill rolls 8. The metal is then cut to form a substrate 7 for a pole plate so that strain and distortion from pulling toward by the bonding of the lead plate 3 can be straightened. In addition, a strip of three-dimensional porous metal 1 may be rolled after bonding of a strip lead plate and then cut to form a substrate 7 for a pole plate. Or, a portion near the lead plate 3 of the substrate 7 for the pole plate formed by cutting may be rolled, or the substrate for the polar plate formed by cutting may be rolled.
