    摘要： After accommodating an electrode group in a battery case having a substantially square transverse cross section, making an opening head of the battery case into a cylindrical shape through compression molding, an annular groove is formed by pressing a groove-forming roller sideways against a side surface of the opening head while rotating the battery case with a pressing force being kept applied to the battery case in an axial direction from the opening portion side, or alternatively pressing the groove-forming roller against the opening head from the side surface thereof and concurrently displacing the groove-forming roller in a direction toward the opening portion of the battery case while rotating the battery case. After having an annular supporting portion that bulges inward of the battery case support an opening-sealing member, the opening-sealing member is fixed through caulking by bending the opening end portion of the battery case inward, whereby a battery is manufactured.

    摘要： A battery case (1, 8), substantially square in cross section, has four lateral walls (5, 6) each of which is gradually arc-shaped to expand outwardly with a radius of curvature R1. The cross section is adapted to satisfy equation R1/r=4 to 20, where r is the distance between a midpoint (C2) of each lateral wall (5, 6) and the center point (C1) in the cross section of the battery case (1, 8) and R1 is the radius of curvature. In addition, the battery case (8) is rounded at each corner with a radius of curvature of R2, and has a cross section that satisfies equation R2/r=0.3 to 0.8, where r is the distance between the midpoint (C2) of each lateral wall (6) and the center point (C1) in the cross section of the battery case (8) and R2 is the radius of curvature of each corner.
