Abstract:
A method for producing a battery pole-plate of the present disclosure comprises: a step (A) for forming a through hole (2) in a belt-shaped pole plate (10); and a step (B) for cutting the belt-shaped pole plate along the width direction. In step (A), the through hole is formed at a position on a cutting line (21) extending in the width direction of the belt-shaped pole plate. In step (B), the belt-shaped pole plate is cut by multiple cutting blades (30A, 30B) disposed along the cutting line and at least one of the multiple cutting blades is disposed at the position of the through hole.
