Description

  The present invention relates to a storage case for storing a film-covered electrical device in which an electrical device element is stored in an exterior film, represented by a battery or a capacitor, a storage member constituting the storage case, and a housing for holding the storage case.

  Batteries used in portable information communication devices such as mobile phones and laptop computers, and small electronic devices such as video cameras and card-type calculators that emphasize their portability are increasingly required to be lighter and thinner. ing. In addition, there are increasing demands for resource saving and energy saving for international protection of the global environment. In addition, the development of electric vehicles and hybrid electric vehicles (hereinafter also simply referred to as “electric vehicles etc.”) equipped with a battery for driving a motor is being rapidly advanced. Of course, batteries mounted on electric vehicles and the like are also required to be light and thin in order to improve steering characteristics and cruising distance.

  In recent years, in order to make a battery lightweight and thin, a battery using a laminate material in which a metal sheet such as aluminum and a heat-weldable resin layer are overlapped with an outer layer through an adhesive layer to form a thin sheet is used. Has been developed. Laminates generally have a structure in which both surfaces of a thin metal layer such as aluminum are covered with a thin resin layer, are resistant to acids and alkalis, and are lightweight and flexible.

  On the other hand, when a battery is used as a power source, an assembled battery in which electrode terminals are connected in series in order to obtain a required voltage from the rated voltage of a single cell or in which electrode terminals are connected in parallel to obtain a required current capacity is used. It is done.

  In many cases, an assembled battery is used in such a manner that a plurality of batteries are combined by fixing a case between the batteries. However, in order to reduce the size of the assembled battery itself, the interval between the batteries is reduced as much as possible, and it is generally difficult to provide a sufficient cooling path between the batteries.

  However, if a variation in cooling occurs in each battery, the life of the assembled battery is remarkably reduced. Therefore, it is particularly required to eliminate the variation in cooling in each battery.

  Therefore, in order to reduce the variation in cooling between the batteries as much as possible, a structure in which a heat radiating member is sandwiched between the batteries is used, and a honeycomb-shaped (hexagonal column hollow) metal plate is inserted between the batteries together with the heat radiating member. There have been proposed assembled battery systems (see, for example, Japanese Patent Application Laid-Open No. 7-122252) and assembled battery systems having wave-like, rectangular, and triangular cooling spacers in close contact with the side surfaces of the secondary battery. (Kaihei 10-112301).

  In the case of a battery having a structure in which battery elements are housed in a can or a resin case, it is relatively easy to construct an assembled battery because the cases of the batteries can be fixed to each other. On the other hand, in the case of a film-clad electrical device, for example, a laminated battery in the form of a flexible film, it is difficult to use the battery itself for fixing.

  For this reason, a configuration is often adopted in which the laminated batteries are not fixed to each other, but are housed in an assembled battery casing and are fixed to the inner wall of the casing to form an assembled battery. However, in such a configuration, the work for storing the assembled battery in the housing becomes complicated, and the workability may be deteriorated. In addition to this, a configuration in which a heat dissipation member is sandwiched between batteries separately in such a configuration further reduces workability.

  Accordingly, an object of the present invention is to provide a storage member, a storage case, and a housing capable of ensuring good cooling characteristics and improving the handleability when using a plurality of film-clad electrical devices.

  In order to achieve the above object, the storage member of the present invention is connected to the electric device element, a flexible outer film that seals the electric device element by heat-sealing the peripheral joint, and the electric device element.

And a plurality of cooling passages integrally formed on the partition wall.

  In addition, since the storage member of the present invention has a cooling path formed in advance, it is not necessary to prepare a separate member for cooling, and therefore, it is easy to make a battery pack. Also, it becomes possible to supply cooling air under the same conditions.

  Further, the storage member of the present invention can prevent damage to the power generation element protected only by the flexible exterior film. For this reason, according to the storage member of this invention, since it does not care about the damage of a film-clad electrical device, a handleability improves.

  Further, in the storage member of the present invention, the first side wall has a receiving wall and an insertion wall, and the two first side walls are such that the interval between the insertion walls is narrower than the interval between the receiving walls. The partition wall may be formed at a position that bisects in the height direction of the second side wall. When the storage member of the present invention is used by stacking the storage members, the insertion wall side can be inserted into the receiving wall side, and the handling property of the plurality of film-covered electrical devices can be further improved.

  Further, the storage member of the present invention may have a plurality of cooling paths formed in a rectangular wave shape, or may be made of resin and integrally formed.

  Moreover, the storage member of the present invention may be one in which a region partitioned by a notch slit is formed on the first side wall.

  The storage member of the present invention may have at least one protrusion on the outer periphery of the frame.

  Further, the storage member of the present invention uses a part of the partition wall as a fulcrum, travels to the receiving part formed by the partition wall and the receiving wall, and presses the joint part of the film-covered electrical device in the receiving part. 1 holding part and a part of the partition wall as a fulcrum, travels to the side of the insertion part that is formed by the partition wall and the insertion wall and is inserted into the receiving part when stacking the storage member, and the first holding You may have a 2nd holding | maintenance part which presses the junction part of the film exterior electrical device in an insertion part in the direction opposite to the direction which a part presses.

  Further, in the storage member of the present invention, the interval between the receiving walls may be narrower than the width of the film-covered electrical device including the joint portion in a direction substantially parallel to the direction in which the electrode terminals extend. .

  The storage case of the present invention includes an electrical device element, a flexible exterior film that seals the electrical device element by thermally bonding the peripheral joint portion, and an electrode connected to the electrical device element and extending from the joint portion. A storage case for storing a film-clad electrical device having a terminal is characterized in that the film-clad electrical device is stored in a storage part formed between the storage members of the present invention that are stacked in the same shape.

  In the storage case of the present invention, the electrode terminal is extended from the cutout of the second side wall into the storage portion formed by the frame and the partition wall by inserting and stacking the insertion portion of the other storage member into the receiving portion of the storage member. The film-clad electrical device can be accommodated in such a manner as to be taken out. Moreover, since the storage case of this invention is accommodated in a storage case, it can protect a film-clad electrical device from an external impact. Further, since the storage case of the present invention fixes the film-covered electrical device by sandwiching the joint portion between the first and second holding portions, the storage case itself does not damage the film-covered electrical device. Thus, since the storage case of this invention can handle a film-clad electrical device without worrying about damage, the handleability is good. In addition, since the storage case of the present invention has a cooling path formed in advance, it is not necessary to prepare a separate member for cooling, so that it is easy to make an assembled battery. Cooling air can be supplied under the same conditions.

In this case, since the joint portion of the film-covered electrical device is folded and stored in the storage portion, space saving can be achieved by the amount of the bending.

  The storage case of the present invention can use a storage member in which a region partitioned by a notch slit is formed on the first side wall of the storage member. In this case, the film-clad electrical device housed in the housing portion with the joint portion bent presses the first side wall. The region delimited by the notch slits on the first side wall applies a reaction force against the pressing force to the film-covered electrical device, whereby the film-covered electrical device can be fixedly held.

  FIG. 1 is a schematic partially broken perspective view of the laminate type battery of the present embodiment.

  The laminate type battery 1 of the present embodiment is formed by superposing a power generation element 11 having a positive electrode side active electrode, a negative electrode side active electrode, and an electrolyte, a metal film such as aluminum, and a heat-fusible resin film. It has a structure in which the laminate film 9 is heat-sealed and sealed at four sides of the heat-sealing portion 9a. That is, the laminate-type battery 1 encloses the power generation element 11 with the heat-fusible resin film of the laminate film 9 inside, and generates heat by heat-sealing the heat-sealing portion 9a that is a peripheral joint. The element 11 and the electrolytic solution are enclosed in the laminate film 9.

  The power generation element 11 of the laminate type battery 1 may be a laminated type composed of a positive electrode side active electrode and a negative electrode side active electrode laminated via a separator (not shown). Alternatively, the power generation element 11 of the laminate-type battery 1 is formed by stacking a belt-like positive electrode side active electrode and a negative electrode side active electrode with a separator interposed therebetween, and then compressing it in a flat shape to compress the positive electrode side active electrode and the negative electrode. A wound type having a structure in which side active electrodes are laminated in an intersecting manner may be used.

  In addition, as the power generation element 11, any power generation element 11 used in a normal battery is applicable as long as it includes a positive electrode, a negative electrode, and an electrolyte. A power generation element 11 in a general lithium ion secondary battery includes a positive electrode plate in which a positive electrode active material such as lithium-manganese composite oxide and lithium cobaltate is applied on both sides of an aluminum foil, and lithium can be doped / undoped. It is formed by facing a negative electrode plate coated with a carbon material on both sides such as a copper foil through a separator and impregnating it with an electrolytic solution containing a lithium salt. Other examples of the power generation element 11 include power generation elements 11 of other types of chemical batteries such as nickel metal hydride batteries, nickel cadmium batteries, lithium metal primary batteries or secondary batteries, and lithium polymer batteries. Furthermore, the present invention is also applicable to an electric device in which a capacitor element exemplified by a capacitor such as an electric double layer capacitor or an electrolytic capacitor is sealed with an exterior film.

  The positive side terminal 4 and the negative side terminal 5 connected to the power generating element 11 are extended from the extending part 12 from the heat-sealing part 9a in the short direction of the laminated battery 1 respectively. Aluminum is often used as the positive terminal 4 and copper or nickel is frequently used as the negative terminal 5 due to its electrical characteristics.

It is the sectional side view seen from the same direction. FIG. 4 is a view showing a storage state of a laminated battery stored by folding a heat-sealing portion in a storage case formed by storage members stacked in two stages. FIG. 5 is a partially enlarged view of FIG. 3A.

  The storage member 20 of the present embodiment is made of resin such as integrally molded PP (polypropylene), and the laminate type battery 1 is stored in the storage portion 21 formed by stacking the storage members 20 having the same shape. The storage case 200 is configured.

  The storage member 20 connects two long side walls 30, each of which includes a receiving wall 32 and an insertion wall 33 connected to the receiving wall 32 by a step 31, and the long side walls 30. In addition, a substantially rectangular frame 60 constituted by two short side walls 40 facing each other is provided. The storage member 20 further divides the inside of the frame 60 in the direction of the frame height at the center height of the short side wall 40, that is, the height that bisects the short side wall 40 in the height direction. 1 has a partition wall 50 that forms a region for storing 1 (a receiving wall side storage portion 21a and a insertion wall side storage portion 21b described later).

  As described above, the storage member 20 is divided into the receiving wall side storage portion 21a and the insertion wall side storage portion 21b by dividing the frame 60 by the partition wall 50 at the center height of the short side wall 40. The receiving wall side storage portion 21 a and the insertion wall side storage portion 21 b constitute a storage portion 21 for storing the laminated battery 1 by stacking the storage members 20. That is, referring to the storage case 200 formed by stacking the storage member 20a on the storage member 20b shown in FIG. 3, the storage portion 21 is inserted between the receiving wall side storage portion 21a of the storage member 20b and the storage member 20a. It is comprised by the wall side accommodating part 21b.

  As described above, the long side wall 30 includes the receiving wall 32 and the insertion wall 33 connected to the receiving wall 32 by the step 31. The storage member 20 is used by being stacked as shown in FIGS. 3A and 3B. At this time, the storage member 20 is stacked by inserting the insertion wall 33 into the receiving wall 32 of the long side wall 30. For this reason, the interval between the insertion walls 33 of the two opposing long side walls 30 is formed to be narrower than the interval between the receiving walls 32. That is, the interval between the outer walls of the insertion wall 33 is narrower than the interval between the inner walls of the receiving wall 32, and does not cause backlash during insertion.

  The interval between the opposing receiving walls 32 in the long side wall 30 is formed so as to be narrower than the width of the laminate type battery 1 including the heat fusion part 9 a of the laminate type battery 1. For this reason, when the laminated battery 1 is stored in the storage portion 21, the heat-sealing portion 9a is bent as shown in FIG. As described above, the storage member 20 can save space by the amount of bending of the heat-sealing portion 9a.

  Since the storage members 20 are fixed to each other in a stacked state, the insertion wall 33 is formed with an engagement claw 34, and the reception wall 32 is engaged with the engagement claw 34 of the stacked storage member 20. An engagement hole 35 for engaging the two is formed. Referring to FIG. 3B, the engaging claw 34 of the insertion wall 33 of the storage member 20a engages with the engagement hole 35 of the receiving wall 32 of the storage member 20b, so that both the storage member 20a and the storage member 20b are mutually connected. It is fixed.

  As shown in FIG. 5, the short side wall 40 is formed with cutouts 41 on the upper and lower sides for extending the positive terminal 4 and the negative terminal 5 (the negative terminal 5 is not shown). Further, on both sides of each notch 41, a positioning portion 42 is formed for positioning in the stacking direction when the storage member 20 is stacked. That is, when the storage member 20 is stacked, the positioning portion 42 on either the upper or lower side of the short side wall 40 is positioned in the stacking direction by contacting the other positioning portion 42 of the other side wall 40 to be stacked. Is done. Referring to FIG. 3B, the positioning in the stacking direction is performed by the positioning portion 42 on the lower side of the storage member 20a coming into contact with the positioning portion 42 on the upper side of the storage member 20b.

  Protrusions 43 are provided on the outer peripheral surface of the short side wall 40 in the vicinity of the four corners of the frame 60. As shown in FIG. 6, when the storage member 20 is stored between the case holding portions 101 formed facing the wall surface of the assembled battery casing 100, the protrusions 43 are recessed portions 102 formed on the wall surface of the case holding portion 101. The housing member 20 is positioned and fixed between the case holding portions 101 by fitting into the case. The assembled battery housing 100 is a housing that houses the plurality of housing members 20 when forming the assembled battery using the plurality of housing members 20, and the assembled battery housing 100 shown in FIG. The part is shown. In this embodiment, four protrusions 43 are formed near the corners of the short side wall 40 as an example. However, the present invention is not limited to this, and the protrusions 43 are formed on the long side wall 30. It may be formed, or the number thereof may be at least one.

  The partition wall 50 has a rectangular wave-shaped cooling path 51 formed substantially parallel to the short side wall 40, and an extended portion 12 from which the positive electrode side terminal 4 and the negative electrode side terminal 5 of the laminated battery 1 extend. And holding part 52 for holding.

  The cooling path 51 is formed so that cooling air for cooling the laminated battery 1 flows in parallel to the short side wall 40. The cooling path 51 includes a first cooling path wall 51a traveling on the receiving wall side storage portion 21a side, a second cooling path wall 51b traveling on the insertion wall side storage portion 21b side, and these cooling paths. And cooling path side walls 51c connecting the walls 51a and 51b. In the cooling path 51, cooling air introduced or discharged through a cooling path opening 51d formed in the long side wall 30 flows. The plurality of cooling paths 51 are arranged in parallel in the direction of the long side wall 30. Due to such a configuration, the long side wall 30 is formed with cooling path openings 51d in a staggered arrangement.

  The first cooling path walls 51a and the second cooling path walls 51b of the plurality of cooling paths 51 arranged in parallel are laminated type batteries on the surface 11a of the region where the power generation element 11 of the laminated type battery 1 is enclosed. 1 is supported (see FIG. 4). Further, since each of the first cooling path walls 51a and each of the second cooling path walls 51b has a uniform height, it is possible to support the laminated battery 1 with an equal surface pressure.

  The holding portion 52 is a cantilever structure member formed integrally with the partition wall 50. The holding portion 52 has a part of the partition wall 50 as a fulcrum 52a, a holding part 52b that makes contact with the extending part 12 of the laminated battery 1, and a bent part 52c that connects the fulcrum 52a and the holding part 52b.

  As shown in FIG. 3B, in the case of the present embodiment, the holding portion 52 is on the business trip to the holding wall 52 'traveling on the receiving wall side storage portion 21a side and on the insertion wall side storage portion 21b side. And holding portions 52 ″ disposed on both sides of 52 ′.

  The holding portion 52 is configured such that the central portion of the extending portion 12 is pressed by the holding portion 52 ′ toward the insertion wall side storage portion 21 b, and the holding portion 52 ″ against the both side portions of the extending portion 12. In other words, the holding part 52 holds the laminate type battery 1 in the storage part 21 by holding the extension part 12 between the holding part 52 ′ and the holding part 52 ″. Hold it in place. The holding part 52 ′ and the holding part 52 ″ fix the laminate type battery 1 without sandwiching the corners of the heat fusion part 9a of the laminate type battery 1. This is because the corners of the heat fusion part 9a are damaged. Therefore, the heat fusion part 9a is sandwiched by avoiding the corner part.

  In order to fix and hold the laminate-type battery 1 in the storage portion 21, not only the method of fixing and holding the laminate-type battery 1 by the holding portion 52 but also two slits 36 in the shape of notches as shown in FIG. The laminate type battery 1 may be fixed and held by bending the wall side holding part 37 between the slits 36, that is, the region divided by the two slits 36. It is preferable that the position and dimensions of the wall-side holding portion 37 are made to correspond to the power generation element 11 of the laminated battery 1 in the state of being housed in the housing portion 21. When the laminate-type battery 1 is stored in the storage unit 21, the portion of the power generation element 11 and the heat-sealed part 9 a in a bent state try to push the wall-side holding part 37 apart. That is, the wall-side holding part 37 holds the laminate-type battery 1 by using a reaction force against the force that the laminate-type battery 1 tries to push the wall-side holding part 37 apart. The storage member 20 may be configured to include both the holding portion 52 and the wall side holding portion 37.

  As described above, according to the present invention, since the laminate type battery 1 is fixedly held in the storage unit 21 by the holding unit 52 or the wall side holding unit 37, the laminate type battery 1 is moved in the storage unit 21 and stored. The member 20 itself does not damage the laminated battery 1.

  As described above, the storage case 200 of the present embodiment configured by stacking the storage members 20 can improve the handleability of the laminate type battery, particularly when the laminate type battery is formed into an assembled battery, and is favorable. Cooling characteristics can also be secured.

  That is, since the storage case 200 of the present embodiment can handle each laminated battery 1 in a state of being stored in the storage case 200, the handleability of the battery can be improved. Conventionally, the power generation element of a laminate-type battery is protected only by a flexible laminate sheet, and the electrode terminals are exposed as they are, so it is necessary to pay sufficient attention to handling them so as not to damage them. . However, the storage case 200 of the present embodiment has a configuration in which the power generation element 11 of the laminate type battery 1 is covered, almost covers both the positive electrode side terminal 4 and the negative electrode side terminal 5, and further the laminate type battery 1. Is firmly fixed and held in the storage portion 21 by the holding portion 52, the laminated battery 1 can be handled without worrying about damage.

  In addition, since the cooling case 51 is formed in advance in the storage member 20 having the same shape, the storage case 200 is easy to configure an assembled battery because there is no need to prepare a separate cooling member. It becomes possible to supply cooling air to any laminate type battery 1 under the same conditions.

  Moreover, although only the example which laminated | stacked the storage case 200 in this embodiment was shown in this embodiment, since all the storage members 20 for comprising the storage case 200 are the same shape, the amount of lamination | stacking is as needed. Therefore, it is very easy to configure the assembled battery. Further, since the storage member 20 has the same shape, the manufacturing cost can be reduced.

  Moreover, since the storage case 200 of this embodiment accommodates the laminated battery 1 by bending the heat-sealing part 9a, it can be reduced in size accordingly.

  Moreover, the storage case 200 of this embodiment can be fixed reliably and easily. That is, since the storage members 20 constituting the storage case 200 can be reliably and easily fixed to each other by the engagement claws 34 and the engagement holes 35, particularly when the storage case is multilayered, Handling property can be improved in terms of being able to handle them collectively. In addition, the storage case 200 can be easily secured by fitting the recess 102 of the case holding portion 101 to the protrusion 43 formed on the frame 60 even when the storage case 200 configured in this way is fixed to the assembled battery housing 100. Positioning and fixing are performed.

  The storage member 20 of the present invention is not only used as a storage case 200 in which the storage members 20 are laminated, but also sandwiches the laminated battery 1 between the storage member 20 and a plate material (not shown) or the wall surface of the housing. Such use is also possible.

In addition, the storage member 20 of the present invention not only constitutes the storage case 200 by inserting the insertion wall side storage portion 21b of the other storage member 20 into the receiving wall side storage portion 21a of one storage member 20, but also a frame. The storage case may be configured by stacking 60 together.
