摘要： A battery case (1) has a cutting groove (10) formed on its elongated side surface (1a). Between a groove bottom surface of the cutting groove (10) and an inner surface of the battery case (1) is provided a thin-walled easily-rupturable portion (12) designed to rupture at an instant when an internal pressure of the battery case (1) reaches a predetermined value. Thereby, a safety mechanism for use with a prismatic battery is realized. The manufacture of the safety mechanism is as follows. A cutting blade (37) rotated at a high speed by a high-speed rotary body (30) is brought into cutting engagement with the elongated side surface (1a) of the battery case (1) of the prismatic battery in finished form until it reaches a predetermined depth and is fixed, and subsequently the high-speed rotary body (30) or the prismatic battery is brought into rectilinear relative movement.

摘要： A center pin is inserted in a hollow cavity of an electrode group of a lithium ion secondary battery. The center pin includes a center portion, a perimeter portion and an end portion. The center portion extends in the radial direction of the hollow cavity. The perimeter portion extends along an inner wall surface of the hollow cavity from an end of the center portion in the radial direction of the hollow cavity. The end portion extends from an end of the perimeter portion in the circumferential direction toward the inside of the hollow cavity to be away from the inner wall surface of the hollow cavity but separated from the center portion.

摘要： A battery case (1) is formed such that a thickness (t1) of a side wall (1a) with respect to a thickness (t0) of a bottom wall (1b) satisfies t1=&agr;t0 (&agr;=0.2 to 0.7) undergoing an ironing step using ironing dies (11, 12, and 13) aligned in multiple stages, and that an inside face of the side wall is made to have a rough surface having average surface roughness of 0.2 &mgr;m to 2.0 &mgr;m by undergoing a drawing step after the ironing step. A manufacturing method of the battery case includes a first step of manufacturing a battery case element (7) by applying the DI processing to a cup-shaped intermediate product (4), and a second step of manufacturing a battery case by reducing an outside diameter to a predetermined outside diameter (r) without changing a thickness of a side wall by applying drawing processing to the battery case element by drawing dies (18 and 19) aligned in multiple stages.

摘要： A gasket that provides sealing between an assembled sealing member and the opening of a battery case includes a high-strength layer inside thereof. The high-strength layer is formed by using a material having a higher strength than that of a gasket body. Examples of such a material include high-strength resins such as polyamide, polyimide and polyphenylene sulfide, and a ceramic. On the other hand, the gasket body is made of a material having a high level of sealing properties. With this configuration, even when extraneous metallic matter or the like is present in a sealed portion, it is possible to prevent both insulating properties and sealing properties of the sealed portion from being impaired.
