- the prismatic storage battery 10 includes a corrugated (corrugated) rectangular tube 11, one lid 12 attached in advance to the rectangular tube 11, and an adjacent gold Metal foils 1 3 and 1 3 are stacked with a slight gap, and connected to L-shaped current collector plates 1 5 and 1 5 through a plurality of lead wires 1 4, and are formed into a rectangular parallelepiped shape as a whole.
- electrode rods 17 and 18 extending from the upper and lower surfaces of the electricity storage element 16, a flat plate portion 2 1 provided with a hole 2 2, and a skirt portion 2 3.
- the sealing material 24 is also provided in one lid body 12.
- the resin plate 20 includes a flat plate portion 21 having a large hole 22 and a skirt portion 23 formed by bending the flat plate portion 21.
- the resin plate 20 can be set to the electricity storage element 16 simply by placing the flat plate portion 21 on the upper surface or the lower surface of the rectangular parallelepiped electricity storage element 16.
- the square tube 1 1 is made of an insulating resin-coated metal plate in which insulating materials 29, 29 such as PET (polyethylene terephthalate) are coated on both sides of a metal plate 28, such as aluminum. It is desirable to use it.
- insulating materials 29, 29 such as PET (polyethylene terephthalate) are coated on both sides of a metal plate 28, such as aluminum. It is desirable to use it.
- the rectangular storage battery 10 includes a rectangular parallelepiped storage element 16, a rectangular tube 11 surrounding the storage element 16, and a lid body 1 2 that closes the opening of the rectangular tube 11,
- a rectangular parallelepiped storage element 16 In order to limit the movement of the sealed case 30 including 25 and the electricity storage element 16, it is inserted into the gaps t, t between the sealed case 30 and the electricity storage element 16, and has an insulating property.
- It consists of resin plates 20 and 20 made of hard resin.
- the resin plate 20 does not have to be detached from the upper and lower surfaces of the rectangular parallelepiped power storage element 16 when it moves in the horizontal direction of the drawing.
- the skirt portion 23 only needs to be placed on the power storage element 16, and even if the length is short, there is no concern that the resin plate 20 is detached from the upper surface or the lower surface of the power storage element 16. That is, since the length of the skirt portion 23 can be shortened, the resin plate 20 can be easily reduced in size and weight.
- FIG. 4 is an enlarged view of the main part of FIG. 3, and when the current collector plate 15 moves to the left in the figure, the skirt portion 23 along the rectangular tube 11 prevents the movement. As a result, there is no concern that the current collector plate 15 rotates even if the nut 27 A (FIG. 3) is turned. The same applies to nut 2 7 B.
- the inner diameter (inside) of the rectangular cylinder 11 can be set to a diameter obtained by adding twice the thickness of the resin plate 20 to the diameter of the electricity storage element 16 (the horizontal dimension in the figure). it can. Since the skirt portion 2 3 is thin, the diameter of the rectangular tube 11 can be suppressed, and the diameter of the storage battery can be reduced.
- a gap can be formed between the inner diameter of the rectangular tube 11 and the outer diameter of the electricity storage element, and a space for storing gas generated from the electrolyte or the like. Can be used.
- the insulation between the rectangular tube 11 and the current collecting element 16 can be left to the resin film.
- the current collecting element 16 is brought into direct contact with the rectangular tube 11, the current collecting element 16 will expand after the expansion due to the thermal expansion and contraction of the rectangular tube 11, etc.
- the resin film on the inner surface wears and peels off, causing poor insulation.
- both the resin film (insulating material 29 in FIG. 2) and the resin plate 20 can exhibit an insulating action. Even if the resin film (insulating material 29 in Fig. 2) is peeled off, the insulating function of the resin plate 20 remains, so there is no risk of causing insulation failure.
- the shape and size of the resin plate 20 are arbitrary. Furthermore, it is also possible to employ an uncoated metal plate that does not cover the insulating resin film on the square tube.
- the lower surface of the lid 12 is called a general surface 31. Shown with imaginary lines In the direction away from the electricity storage element 16, the protrusions 3 2, 3 2 protrude from the lid 12.
- the volume of the pockets 3 4 and 3 4 formed by the protrusions 3 2 is added to the space 3 3 formed by the gap between the electricity storage element 16 and the square tube 11.
- the increase in volume due to the pockets 3 4 and 3 4 can be expected to be 5 to 10 ⁇ 1 ⁇ 2 of the inner volume of the sealed case 30. Since the volume has increased, the pressure change of the gas becomes slow even when the electrolyte is gasified, and the pressure and pressure fluctuations acting on the inner surface of the sealed case 30 can be reduced.
- the lid 12 and the convex part 3 2 should be studied with a three-dimensional structure, but the structure calculation is complicated. Therefore, the lid 1 2 and the convex 3 2 were replaced with two-dimensional “beams” for convenience.
- FIG. 6A shows the general surface 31 and the lid 12 (excluding the convex portion) whose lower surface is in contact with the general surface 31. Further, the general surface 3 1 and the convex portion 3 2 separated from the general surface 3 1 by 2 are schematically shown in FIG. 6B.
- the second-order moment ⁇ b of the convex part 3 2 away from the general surface 3 1 by the distance L 2 is I a + (b-h) x (L 2) 2 Determined.
- the cross-sectional second moment is increased by (b ⁇ h) x (L 2) 2 .
- the bending stress decreases as the cross-section coefficient obtained by multiplying (multiplying) the distance component by the sectional moment of inertia increases. Therefore, the stress is smaller in Fig. 6B than in Fig. 6A. As described above, the convex portion exhibits the effect that the bending is small and the stress (bending stress) is small.
- FIG. 7A to FIG. 7D are comparative views in which a conventional lid and the lid of the present invention are arranged side by side.
- FIG. 7A shows a lid 11 1 1 having no projections. This lid 1 1 1 is referred to as Comparative Example 1.
- FIG. 7B shows a lid body 1 1 3 having an annular convex portion 1 2. The lid body 1 1 3 provided with the annular convex portion 1 1 2 is referred to as Comparative Example 2.
- FIG. 7C shows a lid body 12 having I-shaped convex portions 32 at four corners. This lid 12 is referred to as Example 1.
- FIG. 7D shows a lid 12 having triangular protrusions 32 at four corners. This lid 12 is referred to as Example 2.
- the lid was a three-dimensional “surface”, the periphery was fixed, distribution weight was applied, and stagnation and stress were calculated. The calculation results will be described with reference to FIGS.
- Example 1 is about 1.8 mm, slightly larger than Comparative Example 2.
- Example 2 had a minimum deflection of about 1.4 mm.
- the stress at the center position of the lid body was about 1 3 OMPa in Comparative Example 1 and about 1 1 OMPa in Comparative Example 2.
- Example 1 was about 95 OMPa, which was smaller than Comparative Example 2, and Example 2 was the minimum at about 800 MPa.
- Example 2 had the minimum deflection and the minimum stress.
- the convex portions 32 provided in each of the four corners of the present invention are more flexible and stressed than the conventionally known annular convex portions (Fig. 7 B symbol 1 1 2). Suppress Turned out to be able to. From this, it can be said that it is structurally superior to separate the convex portions from the continuous convex portions (annular convex portions).
- the resin plate 20 includes triangular through holes 36 at the four corners of the flat plate portion 21.
- the through hole 3 6 matches the convex portion 3 2 as shown in FIG.
- the electricity storage element 16 is connected to the pocket 3 4 through the through hole 3 6.
- the gas accumulated inside the square tube 1 1 passes through the through hole 3 6 and reaches the pocket 3 4. Since the pressure can be released directly to the pocket 3 4, changes in internal pressure due to gas can be mitigated.
- the rectangular storage battery 10 of the present invention may be of any type as long as it is a rechargeable electrical product such as a secondary battery, an electrolytic capacitor, or a capacitor.
- the prismatic storage battery according to the present invention is useful for a secondary battery mounted on a vehicle.
