An electrode plate for an alkaline storage battery comprising a conductive core material as a current collector, wherein a plurality of through-holes with radius cut corners are linearly provided in the core material so as to be parallel to a longitudinal direction of the core material,
- wherein
- the through-holes are rectangular in shape with a longer side parallel to the longitudinal direction of the core material,
- rows of through-holes are provided along the longitudinal direction adjacent to one-another in a transverse direction of the core material,
- a space between the through-holes in the longitudinal direction is larger than a space between the adjacent through-holes in the transverse direction,
- the through-holes adjacent to one-another in the transverse direction of the core material are staggered with respect to one another in the longitudinal direction of the core material, and
- each through-hole having an aperture area of 10 mm2 or less and two pairs of opposite sides parallel to each other.
A method for producing electrode plates for an alkaline storage battery, including the steps of:
- pressing a plurality of through-holes with radius cut corners in the core material of the electrode plate, wherein
- the through-holes are linearly provided in the core material so as to be parallel to a longitudinal direction of the core material, and
- wherein
- the through-holes are rectangular in shape with a longer side parallel to the longitudinal direction of the core material,
- rows of through-holes are provided along the longitudinal direction adjacent to one-another in a transverse direction of the core material,
- space through between in the longitudinal direction is larger than a space between the adjacent through holes in the transverse direction,
- the through-holes adjacent to one-another in the transverse direction of the core material are staggered with respect to one another in the longitudinal direction of the core material, and
- each through-hole having an aperture area of 10 mm2 or less and two pairs of opposite sides parallel to each other.
