Method for producing electrode plate group for lead acid battery and method for removing oxide film from electrode plate for lead acid battery

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a lead storage battery electrode group capable of reducing the number of scraps. In order to generate thin sheet-like cutting scraps 9, a pair of opposed facings in the thickness direction of the ear portion 2 is made using a cutting tool 7 to a thickness at which the oxide film 5 is included in the sheet-like cutting scraps 9. However, the cutting waste 9 is kept connected to the ear portion. And in the state which does not isolate | separate the cutting waste 9 from an ear | edge part, when forming the exposed outer surface 6 in a cutting process, the cutting waste 9 is discharged | emitted with the cutting waste 2 ?. Only one piece of waste comes out of one piece of ear, and the advantage that the processing of the waste becomes easy is obtained. [Selection] Figure 3
