  • Patent number: 6620213
    Abstract: A method for manufacturing an electrode plate for a battery includes the following: the regions on both sides of and close to a portion of an electrode sheet to be cut are each fixed between the cutting edges of a pair of upper and lower cutting dies, i.e., the cutting edges of the adjacent cutting dies are in contact with only the regions on both sides of and close to the portion to be cut; two adjacent pairs of upper and lower cutting dies on both sides of the portion to be cut are moved in opposite directions (upward and downward), and thus the electrode sheet is cut at the portion to be cut, resulting in nickel electrode plates having a width of 50 mm and length of 100 mm. This method can suppress the adhesion of fragments to the electrode plate surface and the generation of burrs, thereby reducing the short-circuit failure between the electrode plates incorporated into a battery.
