- the positive and negative external terminals respectively connected to the positive and negative electrode plates are projected to the outside through the through holes of the case.
- the electrode terminal is fixed to the through hole of the case by, for example, caulking a rivet-like member.
- a seal member is usually provided between the pedestal portion of the rivet member and the case in order to seal the inside.
- Patent Document 1 proposes an electrode configuration in which a gasket is sandwiched between a base portion of a rivet member and a case (here, a lid).
- Patent Document 2 describes a structure in which a convex portion is formed on a seating surface and the convex portion is bitten into a sealing material. Thereby, it is said that a sealing performance can be improved.
- Patent Document 3 describes an electrode structure in which an annular convex portion is formed on a seal member. In this document, it is said that the convex portion is compressed and reliably sealed.
- an object of the present invention is to provide a battery having a configuration of an electrode terminal capable of maintaining a reliable sealing property over a long period of time, and a vehicle and a device equipped with the battery.

- the elastic member is sandwiched between the base portion and the battery case inside the hard member. That is, since the elastic member is disposed at a position narrower in the thickness direction than the hard member, the entire elastic member is compressed. Furthermore, since it is an inclined seating surface, the amount of compression increases smoothly inward. Therefore, even if some deformation or inclination occurs on the seating surface of the pedestal, the overall sealing performance is maintained satisfactorily. In addition, since there is no location where stress is concentrated on the elastic member, the sealing performance can be reliably maintained over a long period of time.

- the current collector 34 is connected to the positive electrode plate of the power generation element 16 inside the battery case 11 by, for example, welding.
- Fig. 3 shows a cross-sectional view of the caulked portion after these are fixed.
- the rivet portion 32 of the terminal rivet 31 has a through hole 24a in the seal gasket 24, a through hole 23a in the insulating spacer 23, a through hole 12a in the sealing plate 12, a through hole 22a in the insulating gasket 22, and a lower step portion 21b in the external terminal 21.

- the current collector 34 of the terminal rivet 31 is connected to the positive electrode plate of the power generation element 16. Therefore, the external terminal 21 is connected to the positive electrode plate of the power generation element 16 in the battery case 11 via the terminal rivet 31.
- the positive terminal 14 is connected to the positive plate. Accordingly, the positive terminal 14 functions as a positive terminal.
- the sealing plate 12 is insulated from the terminal rivet 31 by the insulating gasket 22 and the seal gasket 24.
- the sealing plate 12 is also insulated from the inside of the secondary battery 10 by an insulating spacer 23.
- the through hole 21d formed in the lower step portion 21b of the external terminal 21 has a funnel shape in which the hole diameter gradually increases upward in the drawing. Therefore, the terminal rivet 31 can be caulked without difficulty.
- the smallest diameter portion of the through hole 21d and the inner diameters of the through hole 22a of the insulating gasket 22 and the through hole 24a of the seal gasket 24 are such that the rivet portion 32 of the terminal rivet 31 can be passed just through. The hole diameter.
- the outer diameter of the convex portion 33 b is slightly larger than the inner diameter of the through hole 23 a of the insulating spacer 23. Therefore, as shown in FIG. 3, the peripheral portion of the through hole 23a of the insulating spacer 23 abuts over the entire circumference at a location near the edge of the convex portion 33b. Thereby, the distance after crimping of the lower surface in the figure of the sealing board 12 and the upper surface of the convex part 33b of the terminal rivet 31 is ensured. Further, the terminal rivet 31 is prevented from being attached to the sealing plate 12 or the like with an inclination. Alternatively, the insulating spacer 23 may come into contact with the flat plate portion 33a.
- the inner diameter of the through hole 23 a of the insulating spacer 23 is larger than the outer diameter of the seal gasket 24. Accordingly, the seal gasket 24 is disposed inside the through hole 23a of the insulating spacer 23 as shown in FIG.
- the terminal rivet 31 is arranged at a location closer to the rivet portion 32 and having a higher upper surface. Therefore, the distance between the sealing plate 12 and the terminal rivet 31 is smaller than the distance secured by the insulating spacer 23 at the place where the seal gasket 24 is disposed.
- the seal gasket 24 is compressed in the thickness direction over the whole. Further, the vertical width of the space between the lower surface of the sealing plate 12 and the upper surface of the convex portion 33b in the figure is wider toward the outer peripheral side and narrower toward the inner peripheral side. Furthermore, the width of this space changes smoothly. Since the seal gasket 24 is an elastic member, it is arranged in a state where it is compressed without difficulty according to the shape of this space. Therefore, good sealing properties can be obtained.
- the lower surface in FIG. 3 of the inner wall 22b of the through hole 22a of the insulating gasket 22 is preferably in the same plane as the lower surface of the sealing plate 12 in the drawing.
- the width of the portion where the peripheral portion of the through hole 23a of the insulating spacer 23 contacts is L1. This width is a dimension managed when the rivet portion 32 is crimped. Further, the width of the portion where the outer peripheral surface of the seal gasket 24 contacts is L2. In this embodiment, as shown in FIG. 3, L1 ⁇ L2 is satisfied over the entire circumference. That is, the seal gasket 24 is reliably compressed in the thickness direction over the entire circumference.
- the seal gasket 24 is gradually strongly compressed toward the inner peripheral side thereof.
- the width at the place where the width of the space is the smallest, that is, the place adjacent to the rivet portion 32 is L3. This is the place where the seal gasket 24 is most strongly compressed.
- the original width of the seal gasket 24 is the same as the peripheral portion of the through hole 23a of the insulating spacer 23, and is substantially equal to L1.
- the range of the compression amount of the seal gasket 24 is as follows. 0.001mm ⁇ L1-L2 ⁇ L1-L3 ⁇ 0.2mm
- the seal gasket 24 is an elastic member, it is possible to secure the sealability of the portion by compressing to some extent. On the other hand, if it is held for a long time in a state of being compressed too strongly, the elasticity may be lost and the sealing performance may deteriorate. In this embodiment, since the range of the compression amount is set as described above, the sealing performance can be maintained for a long period.
- the flat plate portion 33a of the terminal rivet 31 is provided with the truncated cone-shaped convex portion 33b with the rivet portion 32 as the center. Further, a relatively hard insulating spacer 23 is in contact with the outer peripheral side of the convex portion 33b, and a seal gasket 24, which is an elastic member, is sandwiched between the inner peripheral side. Therefore, the seal gasket 24 is smoothly compressed along the shape of the convex portion 33b. Thereby, stress does not concentrate on the specific location of the seal gasket 24 which is an elastic member. And a reliable sealing performance can be maintained for a long time.
