Description

  The present invention mainly relates to a laminate type cell, a laminate type energy device, a support member, and a mounting structure that are used for current leveling of a power supply circuit unit.

  Conventionally, an aluminum electrolytic capacitor having a large capacity has been inserted into the power supply circuit portion to equalize the current. However, the aluminum electrolytic capacitor has not been able to cope with sharp peaks and large currents. Therefore, it is known to use a laminate type cell instead of such an aluminum electrolytic capacitor for current leveling. Examples of the laminate type cell include an electric double layer capacitor (EDLC), a lithium ion capacitor, and a lithium ion battery (see Patent Documents 1 to 3). For example, as shown in FIG. 19A, a pair of positive and negative lead electrodes 34 a and 34 b are drawn from the laminate type cell 18. When such a laminated cell 18 is mounted on the module substrate 100 such as a power supply circuit unit, as shown in FIG. 19B, the extraction electrodes 34a and 34b are pressed to the module substrate 100 side at a predetermined mounting position. Solder welding is performed in the welding holes 25a and 25b of the solder joint portions 24a and 24b. According to such a laminated cell 18, it is possible to smooth the peak current that cannot be followed by the aluminum electrolytic capacitor.

The arrangement is not specified below. Various modifications can be made to the embodiment of the present invention within the scope of the claims.

[First Embodiment]
(Basic structure of laminated energy device)
With reference to FIGS. 1-10, the basic structure of the lamination type energy device 400 which concerns on 1st Embodiment is demonstrated. That is, the laminate type energy device 400 according to the first embodiment is assumed to be mounted on a module substrate 100 such as a power supply circuit unit as shown in FIG. In general, in addition to the laminated energy device 400, a large number of IC chips 160 and 170, a transformer 120, and other device components 140 are mounted on the module substrate 100.

  In the laminate type energy device 400 according to the first embodiment, the positive and negative electrode lead electrodes 34 are exposed while the separator 30 capable of passing electrolyte and ions is interposed in the positive and negative electrode active material electrodes. In addition, a thin laminate type cell 18 in which a laminate of at least two or more layers laminated so that positive and negative electrodes are alternated is sealed with a laminate sheet, and the laminate type cell 18 is supported, and to the module substrate 100. When the lead-out electrode 34 is inserted into the module substrate 100 via the support member 410, the laminate type cell 18 is mounted vertically with respect to the module substrate 100. A plurality of laminated cells 18 supported on the support member 410 may be arranged. A plurality of laminated cells 18 may be arranged one-dimensionally or two-dimensionally. When mounted on the module substrate 100, the support member 410 separates the laminated cell 18 from the module substrate 100 in the height direction of the module substrate 100. The lead electrode 34 has a flat plate portion at a predetermined length from one end and a substantially rod portion at the other portion. The lead electrode 34 may be a prismatic or columnar electrode lead formed by flattening a portion of a predetermined length from one end. The support member 410 may be a flat plate in which a through hole 412 for inserting the extraction electrode 34 is formed.

  Hereinafter, it explains in more detail using a drawing.

  2A and 2B are diagrams for explaining the punching electrode 18a according to the first embodiment. FIG. 2A is a schematic plane pattern configuration diagram before lamination, and FIG. 2B is a diagram after lamination. It is a typical plane pattern block diagram. First, as shown in FIG. 2A, the aluminum foil coated with the active material is punched into an arbitrary shape by a punching die. Next, with the separator 30 interposed, as shown in FIG. 2B, positive and negative punching electrodes 18a are stacked. A portion (welded portion) 18b where the lead electrode 34 is welded to the punch electrode 18a is punched into a tapered shape with a width wider than that of the lead electrode 34. If it does in this way, the intensity of welding part 18b can be raised.

  3A and 3B are diagrams for explaining the extraction electrode 34 according to the first embodiment. FIG. 3A is a schematic plan pattern configuration diagram before processing, and FIG. 3B is a diagram before processing. FIG. 3C is a schematic bottom pattern configuration diagram after processing, and FIG. 3D is a schematic bottom pattern configuration diagram after processing. First, as shown in FIGS. 3A and 3B, prismatic electrode leads are prepared. Next, as shown in FIGS. 3C and 3D, a portion having a predetermined length is crushed from the upper end of the prismatic electrode lead into a flat plate shape. The portion of the predetermined length is a region above the one-dot chain line in the figure. This region may be a region larger than the welded portion 18b, and can be appropriately adjusted to an arbitrary size. The portion other than the upper end is left in a prismatic shape that can be inserted into the module substrate 100.

  Next, as shown in FIG. 4A, the upper ends of the positive and negative lead electrodes 34 are welded to the welded portion 18b of the punched electrode 18a after lamination. The upper end of the extraction electrode 34 is crushed into a flat plate shape. Then, after impregnating with an electrolytic solution and compressing and sealing the laminate sheet along a predetermined laminate line 18c, a press treatment is performed on a line slightly outside the laminate line 18c to remove unnecessary laminate sheets. As a result, a thin laminate type cell 18 in which the positive and negative lead electrodes 34 are drawn from one side surface is obtained.

  FIG. 4A illustrates the two-terminal laminated cell 18 including two extraction electrodes 34. However, as illustrated in FIG. 4B, three extraction electrodes 34 may be provided. Such a three-terminal laminated cell 18 can be realized by connecting two two-terminal laminated cells 18 in series.

  FIG. 5 is a schematic bird's-eye view structure diagram of the laminate type energy device 400 according to the first embodiment. As shown in this figure, the extraction electrode 34 is inserted into the support member 410, and the plurality of laminated cells 18 are arranged in an array at a constant pitch. If the support member 410 is used, it is possible to avoid inserting the laminated cell 18 into the module substrate 100 deeper than necessary.

(Support member)
FIGS. 6A and 6B are views for explaining the two-terminal support member 410 according to the first embodiment, and are (a) a schematic plane pattern configuration diagram and (b) a schematic cross-sectional configuration diagram.

  The two-terminal support member 410 according to the first embodiment is configured so that the positive and negative electrode lead electrodes 34 are exposed while the separator 30 capable of passing the electrolyte and ions is interposed between the positive and negative electrode active material electrodes. And an insertion portion (through hole 412) into which a thin laminate type cell 18 in which a laminate of at least two or more layers laminated so that positive electrodes and negative electrodes are alternately laminated with a laminate sheet can be inserted; And an adjustment unit (through hole 412) for adjusting the mounting position of the laminate type cell 18 on the module substrate 100.

  FIG. 6 illustrates a flat plate type support member 410. The thickness of the support member 410 is, for example, about 5 mm, but can be appropriately changed according to the length of the extraction electrode 34, the thickness of the module substrate 100, and the like. A plurality of grooves 411 are formed at a constant pitch in the short direction when the support member 410 is viewed in plan. Hole processing is performed at the bottom of each groove 411, and a through hole 412 reaching the back surface of the support member 410 is formed. When the extraction electrode 34 is inserted into the through hole (insertion portion) 412, the thin laminate type cell 18 is vertically fitted into the groove 411 so that the extraction electrode 34 is exposed from the back side of the support member 410. By adjusting the depth of the through hole (adjusting part) 412, the mounting position of the laminate type cell 18 on the module substrate 100 can be adjusted. The material of the support member 410 may be any material that is resistant to heat, such as plastic or PPE (poly phenylene ether).

  When the laminate type energy device 400 is mounted on the module substrate 100, a part of the support member 410 is interposed between the module substrate 100 and the laminate type cell 18. In other words, the support member 410 separates the laminated cell 18 from the module substrate 100 in the height direction of the module substrate 100. The height direction of the module substrate 100 is a direction perpendicular to the mounting surface of the module substrate 100. As described above, when the support member 410 is used, the distance from the module substrate 100 to the laminate type cell 18 at the time of mounting can be increased, and heat transfer to the laminate type cell 18 can be suppressed.

  In FIG. 6, since the support member 410 for two terminals is illustrated, two through holes 412 are formed in one groove 411. In the support member 410 for three terminals, as shown in FIG. 7, three through holes 412 are formed in one groove 411.

(Mounting structure)
In the mounting structure according to the first embodiment, the positive and negative electrode lead electrodes 34 are exposed while the module substrate 100 and the positive and negative electrode active material electrodes are interposed with the separator 30 through which the electrolyte and ions can pass. In addition, a thin laminate cell 18 in which at least two or more laminates in which positive electrodes and negative electrodes are alternately laminated is sealed with a laminate sheet, the laminate cell 18 is supported, and a module substrate When the lead electrode 34 is inserted into the module substrate 100 via the support member 410, the laminate type cell 18 is mounted vertically with respect to the module substrate 100. .

  That is, as shown in FIG. 8A, the extraction electrode 34 exposed from the back side of the support member 410 is inserted into the mounting position of the module substrate 100 and soldered on the back surface of the module substrate 100. Thereby, the laminate type cell 18 and the module substrate 100 are electrically connected. A plurality of laminated cells 18 may be connected in series by a wiring pattern on the module substrate 100 side.

  As described above, the laminate type energy device 400 can be mounted vertically on the module substrate 100 in the same manner as a conventional lead type aluminum electrolytic capacitor. Moreover, the laminate type cell 18 is thin and is not a cylindrical shape like the conventional aluminum electrolytic capacitor 500 (see FIG. 8B). Therefore, it is possible to reduce the mounting occupation area as compared with the conventional aluminum electrolytic capacitor 500 (L10 <L11). Of course, it is also possible to smooth the peak current that could not be followed by the conventional aluminum electrolytic capacitor.

  In addition, as shown in FIG. 9, you may adhere | attach the upper end of each lamination type cell 18 mutually with the adhesive 18d. Of course, the part to be bonded with the pressure-sensitive adhesive 18d is not limited to the upper end of the laminated cell 18, and may be, for example, a side surface.

  As shown in FIG. 10, an insulating film may be formed on the outer surface of the laminate type energy device 400 by powder coating. In order to avoid the laminated energy device 400 from becoming high temperature, the outer surface of the laminated energy device 400 may be covered with an insulating film, for example, by a room temperature curing resin mold. Various known methods can be employed as a method of powder coating or resin molding.

  Further, here, the case of using a prismatic electrode lead is illustrated, but the shape of the electrode lead may be a substantially rod shape. For example, the same effect can be obtained by using a cylindrical electrode lead instead of the prismatic electrode lead.

  Further, here, the laminate type energy device 400 in which the laminate type cells 18 are arranged one-dimensionally is illustrated, but the arrangement method is not limited to this. For example, a laminate type energy device 400 in which the laminate type cells 18 are two-dimensionally arranged can be adopted.

  In the above description, in the laminate type energy device 400 according to the first embodiment, the EDLC is exemplified as the laminate type cell 18, but a lithium ion capacitor, a lithium ion battery, or the like may be adopted as the laminate type cell 18. .

The extraction electrodes 34a and 34b are made of, for example, aluminum foil, and the active material electrodes 10 and 12 are made of, for example, activated carbon. The separator 30 is larger than the active material electrodes 10 and 12 (having a large area) so as to cover the entire active material electrodes 10 and 12. The separator 30 does not depend on the type of energy device in principle, but heat resistance is required particularly when reflow treatment is required. When heat resistance is not required, polypropylene or the like can be used, and when heat resistance is required, a cellulosic material can be used. The EDLC internal electrode is impregnated with an electrolytic solution, and the electrolytic solution and ions move through the separator 30 during charging and discharging.

The extraction electrodes 34a and 34b1 are connected to the power supply voltage. The active material electrode 12 on the positive electrode side is made of, for example, activated carbon, and the active material electrode 11 on the negative electrode side is made of, for example, Li-doped carbon. The lead electrode 34a on the positive electrode side is made of, for example, an aluminum foil, and the lead electrode 34b1 on the negative electrode side is made of, for example, a copper foil. The separator 30 is larger than the active material electrodes 11 and 12 (having a large area) so as to cover the entire active material electrodes 11 and 12. The lithium ion capacitor internal electrode is impregnated with an electrolytic solution, and the electrolytic solution and ions move through the separator 30 during charging and discharging.

The active material electrode 12a on the positive electrode side is made of, for example, LiCoO _2, and the active material electrode 11 on the negative electrode side is made of, for example, Li-doped carbon. The lead electrode 34a on the positive electrode side is made of, for example, an aluminum foil, and the lead electrode 34b1 on the negative electrode side is made of, for example, a copper foil.

  As described above, according to the first embodiment, when the extraction electrode 34 is inserted into the module substrate 100 via the support member 410, the laminated cell 18 is arranged in the vertical direction with respect to the module substrate 100. Therefore, a large capacity and space saving can be achieved. If the support member 410 is used, it is possible to avoid inserting the laminated cell 18 into the module substrate 100 more deeply than necessary.
