Description

本発明は、電池やキャパシタに代表される、電気デバイス要素を外装フィルムに収容したフィルム外装電気デバイスを収納する収納ケース、およびこの収納ケースを構成する収納部材、フィルム外装電気デバイスに関する。   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 film-covered electrical device.

一般に複数の電池を接続して用いる場合、電池の保護や利便性といった理由からケースに収納された状態で用いられる（例えば、特許文献１参照）。   In general, when a plurality of batteries are connected and used, they are used in a state of being housed in a case for reasons such as battery protection and convenience (see, for example, Patent Document 1).

ところで、近年、モータ駆動用のバッテリを搭載する電気自動車やハイブリッド電気自動車（以下、単に「電気自動車等」ともいう）の開発が急速に進められつつある。電気自動車等に搭載される電池にも、電気自動車の操縦特性、走行距離を向上させるため、当然ながら、軽量、薄型化が求められている。電池を軽量かつ薄型とするため、その外装体にアルミニウムなどの金属層と熱溶着性の樹脂層とを接着剤層を介して重ね合わせて薄いフィルムとなしたラミネート材を用いたフィルム外装電池が開発されている。ラミネート材は、一般に、アルミニウム等の薄い金属層の両表面を薄い樹脂層で被覆した構造をなしており、酸やアルカリに強く、かつ軽量で柔軟な性質を有するものである。   By the way, in recent years, the development of electric vehicles and hybrid electric vehicles (hereinafter also simply referred to as “electric vehicles and the like”) equipped with a battery for driving a motor is being rapidly advanced. Naturally, batteries mounted on electric vehicles and the like are also required to be lightweight and thin in order to improve the driving characteristics and travel distance of electric vehicles. In order to make the battery lighter and thinner, a film-clad battery using a laminate material in which a metal layer such as aluminum and a heat-weldable resin layer are laminated on the outer package through an adhesive layer to form a thin film. Has been developed. The laminate material generally has a structure in which both surfaces of a thin metal layer such as aluminum are covered with a thin resin layer, and is resistant to acids and alkalis, and has a lightweight and flexible property.

発電要素をラミネート材で被覆したフィルム外装電池は、軽量である一方、剛性が低く、振動、衝撃の影響を受け易い。このため、個々の電池を個別にケースに収納し、外部からの衝撃等から電池を保護する必要がある。フィルム外装電池の形状は一般に平板形状である。このような平板形状のフィルム外装電池を収納するケースは、電池の収納あるいはケースから取り出す際の利便性を考慮して電池の主面の法線方向に開閉する蓋を有する構成、換言すれば、電池要素の主面側から挟み込む二分割されたケースが多く採用されている。   A film-clad battery in which a power generation element is covered with a laminate material is lightweight, but has low rigidity and is easily affected by vibration and impact. For this reason, it is necessary to individually store each battery in a case and protect the battery from external impacts and the like. The shape of the film-clad battery is generally a flat plate shape. The case for storing such a flat-shaped film-clad battery has a lid that opens and closes in the normal direction of the main surface of the battery in consideration of convenience when storing or taking out the battery, in other words, Many cases are used that are divided into two from the main surface side of the battery element.

フィルム外装電池は、ケースに収納されることで外部からの振動、衝撃からは保護されるものの、ケースに収納されたフィルム外装電池がケース内で動いてしまうと、ケースがフィルム外装電池の外装を痛めたり、あるいは電極に無理な力がかかることで電池が破損してしまう。そこで、ケース内での電池の固定のため、ケースと電池との間に発泡剤等の充填剤が充填されることもある。
実開平０７−０１９９４７号公報 Although the film-clad battery is protected from external vibrations and shocks when it is housed in the case, if the film-clad battery contained in the case moves within the case, the case wraps the exterior of the film-clad battery. The battery may be damaged due to pain or excessive force applied to the electrodes. Thus, in order to fix the battery in the case, a filler such as a foaming agent may be filled between the case and the battery.
Japanese Utility Model Publication No. 07-019477

フィルム外装電池をケース内にしっかり固定させること、また、ケースを落下させた場合、外部からの衝撃を有効に吸収するためにケースの四隅に所定の充填量の充填剤が充填されることは極めて重要となる。しかしながら、電池要素の主面側から挟み込む二分割されたケースの場合、充填剤がケースの合わせ目から漏洩してしまう場合があった。   It is extremely difficult to firmly fix the film-clad battery in the case, and when the case is dropped, the four corners of the case are filled with a predetermined amount of filler in order to effectively absorb external shocks. It becomes important. However, in the case of a two-divided case sandwiched from the main surface side of the battery element, the filler may leak from the joint of the case.

また、ケースが、フィルム外装電池を収納する収納部と、この収納部に対する蓋とで構成される場合、収納部と蓋との２種類の部材が必要となり部品点数が増えてしまう問題もあった。   In addition, when the case is configured by a storage unit that stores the film-clad battery and a lid for the storage unit, there is a problem that two types of members, the storage unit and the cover, are required and the number of parts increases. .

そこで、本発明は充填剤の漏洩しにくい、特にケースの隅部からの充填剤が漏洩しない収納ケース、収納部材およびフィルム外装電気デバイスを提供することを目的とする。   Accordingly, an object of the present invention is to provide a storage case, a storage member, and a film-covered electrical device in which the filler is difficult to leak, and in particular, the filler from the corner of the case does not leak.

上記目的を達成するため本発明の収納ケースは、電気デバイス要素と、周縁の接合部が熱融着されることで電気デバイス要素を封止する柔軟な外装フィルムと、電気デバイス要素に接続され接合部から延出した電極端子とを有するフィルム外装電気デバイスを収納する収納ケースにおいて、少なくともフィルム外装電気デバイスの角部を覆う隅部が継ぎ目なく一体的に形成された、同一形状の２つの収納部材が接合されてなることを特徴とする。   In order to achieve the above object, the storage case of the present invention includes an electrical device element, a flexible outer film that seals the electrical device element by thermally bonding the peripheral joint portion, and a connection case connected to the electrical device element. Two storage members of the same shape, in which a corner covering at least a corner of the film-covered electrical device is integrally formed seamlessly in a storage case for storing a film-covered electrical device having electrode terminals extending from the portion Are joined together.

本発明の収納ケースは隅部が継ぎ目なく一体的に形成されている。このため、フィルム外装電気デバイスの角部を固定するための充填剤が隅部に充填された場合であっても、充填剤が外部に漏洩することはない。よって、所定の量の充填剤が隅部に充填され、フィルム外装電気デバイスの固定が確実なものとなる。

また、本発明の収納ケースは、収納部材同士が当接する面である接合面が電気デバイス要素の主面上に位置するようにして各収納部材が接合されているものであってもよい。収納部材同士の接合面が主面上に位置する、すなわち、収納部材の合わせ面が収納部材の隅部以外に位置するため、隅部に充填剤を充填しても合わせ面から充填剤が漏洩してしまうことはない。 In the storage case of the present invention, the corners are integrally formed without a seam. For this reason, even if it is a case where the filler for fixing the corner | angular part of a film-clad electrical device is filled into a corner, a filler does not leak outside. Therefore, a predetermined amount of filler is filled in the corners, and the film-clad electrical device is securely fixed.

In addition, the storage case of the present invention may be one in which the storage members are joined such that the joint surface, which is the surface on which the storage members abut, is positioned on the main surface of the electric device element. Since the joint surface between the storage members is located on the main surface, that is, the mating surface of the storage member is located outside the corner of the storage member, the filler leaks from the mating surface even if the corner is filled with the filler. There is no end to it.

また、本発明の収納ケースの収納部材は、収納部材同士が当接する面である接合面に、先端部に係合爪が設けられた係合部を有し、他の収納部材の係合爪に対応する位置に係合爪が係合する係合穴が形成されているものであってもよい。本発明の収納ケースは同一形状の２つの収納部材を接合して構成されるものであるが、係合爪を備えた係合部と係合穴とを係合させることで両者を互いに接合させるので、ケースの開閉が可能であり、かつ容易である。   In addition, the storage member of the storage case of the present invention has an engagement portion with an engagement claw provided at the tip on the joint surface, which is a surface where the storage members abut, and the engagement claw of the other storage member An engagement hole with which the engagement claw engages may be formed at a position corresponding to. The storage case of the present invention is configured by joining two storage members having the same shape, and by joining the engagement portion provided with the engagement claw and the engagement hole, the two are joined to each other. Therefore, the case can be opened and closed easily.

また、本発明の収納ケースは、収納部材の一端側に係合部を有し、他端側に係合穴が形成されているものであってもよい。この場合、一の収納部材に対して、他の収納部材を係合部と係合穴との間の仮想軸を中心に反転させて、両者を接合させることとなる。つまり、接合方向を間違えることなく容易に両者を接合させることができる。   Moreover, the storage case of this invention may have an engaging part in the one end side of a storage member, and the engagement hole may be formed in the other end side. In this case, with respect to one storage member, the other storage member is reversed about the virtual axis between the engagement portion and the engagement hole, and both are joined. That is, both can be easily joined without making a mistake in the joining direction.

一の収納部材の接合面と他の収納部材の接合面とを当接させて、一の収納部材の係合爪を、他の収納部材の係合穴に係合させることで収納部材同士の接合がなされるものであってもよい。   By bringing the joint surface of one storage member and the joint surface of the other storage member into contact with each other and engaging the engaging claws of the one storage member with the engagement holes of the other storage member, Bonding may be performed.

また、本発明の収納ケースの各収納部材は同一形状であってもよい。この場合、部品の種類を減らすことができる。   Further, the storage members of the storage case of the present invention may have the same shape. In this case, the types of parts can be reduced.

本発明の収納部材は、電気デバイス要素と、周縁の接合部が熱融着されることで電気デバイス要素を封止する柔軟な外装フィルムと、電気デバイス要素に接続され接合部から延出した電極端子とを有するフィルム外装電気デバイスを収納する収納ケースを構成するものである。   The storage member of the present invention includes an electrical device element, a flexible outer 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 configured.

本発明のフィルム外装電気デバイスは、電気デバイス要素と、周縁の接合部が熱融着されることで前記電気デバイス要素を封止する柔軟な外装フィルムと、前記電気デバイス要素に接続され前記接合部から延出した電極端子とを有するフィルム外装電気デバイスにおいて、本発明の収納ケースに収納されていることを特徴とする。   The film-clad electrical device of the present invention includes an electrical device element, a flexible exterior film that seals the electrical device element by thermally bonding a peripheral joint part, and the joint part connected to the electrical device element. A film-covered electrical device having an electrode terminal extending from the housing is housed in the housing case of the present invention.

本発明によれば、収納ケースの隅部が継ぎ目なく一体的に形成されているため、充填剤が隅部に充填された場合であっても、充填剤が外部に漏洩することはない。よって、所定の量の充填剤が隅部に充填され、フィルム外装電気デバイスの固定が確実なものとなる。   According to the present invention, since the corners of the storage case are integrally formed without a seam, the filler does not leak to the outside even when the filler is filled in the corners. Therefore, a predetermined amount of filler is filled in the corners, and the film-clad electrical device is securely fixed.

[Film battery]
The film-clad battery 1 of the present embodiment is formed by superposing a power generation element 2 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. And a laminate film 7. The film-clad battery 1 has a structure in which the power generation element 2 is sealed with two laminated films 7. That is, in the film-clad battery 1 of the present embodiment, among the four heat-seal portions 7a of the laminate film 7, first, three sides are heat-sealed to form a bag shape, and the remaining one side that is open The power generation element 2 is hermetically sealed by two laminate films 7 by exhausting the air from the inside and evacuating it, and then heat-sealing the remaining one side of the heat-sealing part 7a. It is.

フィルム外装電池１の発電要素２は、セパレータを介して積層された正極側活電極と負極側活電極とからなる積層型であってもよいし、あるいは、帯状の正極側活電極と負極側活電極とをセパレータを介して重ねこれを捲回した後、扁平状に圧縮することによって正極側活電極と負極側活電極とが交互に積層された構造の捲回型であってもよい。   The power generating element 2 of the film-clad 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, or a strip-like positive electrode side active electrode and a negative electrode side active electrode. A wound type having a structure in which the positive electrode side active electrodes and the negative electrode side active electrodes are alternately stacked by stacking the electrodes through a separator and then winding the electrodes into a flat shape may be used.

また、発電要素２としては、正極、負極および電解質を含むものであれば、通常の電池に用いられる任意の発電要素が適用可能である。一般的なリチウムイオン二次電池における発電要素は、リチウム・マンガン複合酸化物、コバルト酸リチウム等の正極活物質をアルミニウム箔などの両面に塗布した正極板と、リチウムをドープ・脱ドープ可能な炭素材料を銅箔などの両面に塗布した負極板とを、セパレータを介して対向させ、それにリチウム塩を含む電解液を含浸させて形成される。発電要素２としては、この他に、ニッケル水素電池、ニッケルカドミウム電池、リチウムメタル一次電池あるいは二次電池、リチウムポリマー電池等、他の種類の化学電池の発電要素が挙げられる。さらに、本発明は、電気二重層キャパシタなどのキャパシタや電解コンデンサなどに例示されるキャパシタ要素のような、電気エネルギを内部に蓄積し化学反応または物理反応でガスが発生しうる電気デバイス要素を外装フィルムで封止した電気デバイスにも適用可能である。   In addition, as the power generation element 2, any power generation element used for a normal battery is applicable as long as it includes a positive electrode, a negative electrode, and an electrolyte. The power generation elements in a typical lithium ion secondary battery include 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, etc., and carbon that can be doped and dedoped with lithium. A negative electrode plate coated with a material on both sides of a copper foil or the like is opposed with a separator interposed therebetween, and is impregnated with an electrolytic solution containing a lithium salt. Other examples of the power generation element 2 include power generation elements 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 provides an external device that stores electrical energy and can generate gas by chemical reaction or physical reaction, such as a capacitor element exemplified by a capacitor such as an electric double layer capacitor and an electrolytic capacitor. The present invention can also be applied to an electric device sealed with a film.

フィルム外装電池１の短手方向の熱融着部７ａからは、正極用電極端子３および負極側活電極に接続された負極用電極端子４がそれぞれ対向して延出している。正極用電極端子３としてはアルミニウムが多く用いられ、また、負極用電極端子４としては銅またはニッケルがその電気的特性により多く用いられている。以下、正極用電極端子３と負極用電極端子４とをまとめて単に電極と称する場合もある。   A positive electrode terminal 3 and a negative electrode terminal 4 connected to the negative active electrode extend from the heat-sealed portion 7a in the short direction of the film-clad battery 1, respectively. Aluminum is often used for the positive electrode terminal 3, and copper or nickel is often used for the negative electrode terminal 4 due to its electrical characteristics. Hereinafter, the positive electrode terminal 3 and the negative electrode terminal 4 may be collectively referred to as electrodes.

フィルム外装電池１の長手方向の熱融着部７ａにはその一部を、他の部分よりも熱融着強度を弱くし、他の部分よりも低い圧力で融着が剥がれるようにしたガス排出部８が設けられている。   A part of the heat-sealed portion 7a in the longitudinal direction of the film-clad battery 1 is gas exhausted so that the heat-sealing strength is weaker than that of other portions and the fusion is peeled off at a lower pressure than the other portions. A part 8 is provided.

電池の使用時において、電池に規格範囲外の電圧が印加されたりすると、電解液溶媒の電気分解によりガス種が発生し、電池の内圧が上昇することがある。さらに、電池が規格範囲外の高温で使用されたりしても、電解質塩の分解などによりガス種が生成されたりする。基本的には、規格範囲内で電池を使用してガスを発生させないようにすることが理想的であるが、電池の制御回路が何らかの原因で故障して異常な電圧が印加されたり、何らかの原因で周囲が異常に高温となったりすると、場合によっては大量にガスが発生することもある。   If a voltage outside the standard range is applied to the battery during use of the battery, gas species may be generated due to electrolysis of the electrolyte solvent, and the internal pressure of the battery may increase. Furthermore, even if the battery is used at a high temperature outside the standard range, gas species are generated due to decomposition of the electrolyte salt or the like. Basically, it is ideal to use the battery within the standard range so that gas is not generated, but the battery control circuit fails for some reason and abnormal voltage is applied, or for some reason If the surroundings become abnormally hot, a large amount of gas may be generated in some cases.

このような、電池内部でのガスの発生は、電池の内圧上昇をもたらす。内圧が極度に上昇し電池が暴発することを防ぐために、外装材として金属缶を用いた電池の多くは、電池の内圧が上昇した際にガスを電池の外部に逃がす圧力安全弁を有している。しかし、フィルムを外装材とするフィルム外装電池においては、圧力安全弁を設けることが構造上難しい。フィルム外装電池では内圧が上昇しすぎるとフィルムが膨張し、最終的には外装材が破裂しその箇所からガスが噴出するが、破裂がどの箇所で発生するか特定できないため、破裂した箇所によっては周囲の機器等に悪影響を及ぼすことがある。   Such generation of gas inside the battery causes an increase in the internal pressure of the battery. In order to prevent the internal pressure from excessively rising and the battery from exploding, many batteries using metal cans as exterior materials have a pressure safety valve that allows gas to escape outside the battery when the internal pressure of the battery increases. . However, it is structurally difficult to provide a pressure safety valve in a film-clad battery using a film as a packaging material. If the internal pressure is too high in a film-clad battery, the film expands and eventually the exterior material ruptures and gas is ejected from that location, but it is not possible to specify where the rupture occurs, so depending on the location where the rupture occurred It may adversely affect surrounding equipment.

そこで、フィルム外装電池１においては、こういった電池内部でのガスの発生による不具合を解消するため、上述したようなガス排出部８を熱融着部７ａに設けている。   Therefore, in the film-clad battery 1, the gas discharge part 8 as described above is provided in the heat-sealing part 7 a in order to eliminate such problems caused by the generation of gas inside the battery.

フィルム外装電池１の周囲を囲む収納ケース１０は、２つの収納部材１０ａからなる。２つの収納部材１０ａは同一形状であり、一方の収納部材１０ａに対して他方の収納部材１０ａを図１中Ｚ軸周りに反転させ、これらを接合することで収納ケース１０が構成される。
［収納部材］
収納部材１０ａは、第１の側部１１と第２の側部１２と、これら第１および第２の側部１１、１２の間に平行に設けられた中間部１３と、第１および第２の側部１１、１２および中間部１３とを繋ぐ接続部１４、１５を有し、これらにより、概ね枠形状の収納部材１０ａが構成されている。また、収納部材１０ａには、第１および第２の側部１１、１２と接続部１４、１５とによって形成される、フィルム外装電池１を冷却するための冷却用開口部１８が形成されている。
［第１の側部および第２の側部］
第１の側部１１は枠形状の収納部材１０ａの短辺部分を構成するとともに、収納部材１０の短辺部分を構成する。 A storage case 10 surrounding the film-clad battery 1 is composed of two storage members 10a. The two storage members 10a have the same shape, and the storage case 10 is configured by reversing the other storage member 10a around the Z axis in FIG.
[Storage material]
The storage member 10 a includes a first side portion 11 and a second side portion 12, an intermediate portion 13 provided in parallel between the first and second side portions 11 and 12, and the first and second portions. Connecting portions 14 and 15 that connect the side portions 11 and 12 and the intermediate portion 13 to each other, thereby forming a substantially frame-shaped storage member 10a. The storage member 10a has a cooling opening 18 formed by the first and second side portions 11 and 12 and the connection portions 14 and 15 for cooling the film-clad battery 1. .
[First side and second side]
The first side portion 11 constitutes the short side portion of the frame-shaped storage member 10 a and the short side portion of the storage member 10.

第１の側部１１の側面１１ａには電極を外部に延出させるための切り欠き１１ｂが形成されている。この切り欠き１１ｂは第１の側部１１の対向面１１ｄ（接合して用いられる収納部材１０ａと突合せとなる面）側に開いており、電極の幅の半分以上切り欠かれている。   On the side surface 11a of the first side portion 11, a notch 11b for extending the electrode to the outside is formed. The notch 11b is open on the side of the opposing surface 11d of the first side portion 11 (the surface facing the storage member 10a used for joining), and is cut out by more than half the width of the electrode.

対向面１１ｄには後述する係合穴１２ｅに係合する係合部１１ｃ1、１１ｃ2が突出して形成されている。係合部１１ｃ1と係合部１１ｃ2とは切り欠き１１ｂを挟んで向かい合わせに形成されており、これらの先端部には係合爪１１ｅが設けられている。各係合爪１１ｅは係合部１１ｃ1、１１ｃ2の向かい合わせた面側には形成されておらず、該向かい合わせた面は電極の差込みを阻害しないように平滑な面になっている。 Engagement portions 11c 1 and 11c 2 that engage with engagement holes 12e described later are formed on the facing surface 11d so as to protrude. The engaging portion 11c 1 and the engaging portion 11c 2 are formed to face each other with the notch 11b interposed therebetween, and an engaging claw 11e is provided at the tip portion thereof. Each engaging claw 11e is not formed on the facing surface side of the engaging portions 11c 1 and 11c 2 , and the facing surface is a smooth surface so as not to inhibit the insertion of the electrodes.

第２の側部１２は枠形状の収納部材１０ａの短辺部分を構成するとともに、収納部材１０の短辺部分を構成する。   The second side portion 12 constitutes the short side portion of the frame-shaped storage member 10 a and the short side portion of the storage member 10.

第２の側部１２の側面１２ａにも電極を外部に延出させるための切り欠き１２ｂが形成されている。この切り欠き１２ｂも切り欠き１１ｂと同様に第２の側部１２の対向面１２ｄ側に開いており、電極の幅の半分以上切り欠かれている。   A cutout 12 b for extending the electrode to the outside is also formed on the side surface 12 a of the second side portion 12. Similarly to the notch 11b, the notch 12b is open on the facing surface 12d side of the second side portion 12, and is notched more than half of the width of the electrode.

That is, the dividing line 40 of the storage case 10 is formed so as to pass over the main surface 2a of the film-clad battery 1, and is not formed at the corner 20 of the storage member 10a. In the case of a storage case that is divided in the normal direction of the main surface 2a of the film-clad battery 1, a split line (a mating surface of the storage member) is formed at the corner. In the configuration in which the mating surfaces are formed at the corners, when the filler for fixing the film-clad battery 1 in the storage case 10 is filled in the four corners of the case, the filler leaks from the mating surfaces, and the filler This makes it difficult to securely fix the battery.

しかしながら、本実施形態の収納ケース１０は、上述したように分割ライン４０、すなわち、収納部材１０ａの合わせ面が隅部２０には形成されない。このため、隅部２０の充填部３０に充填された充填剤３１が漏洩することがなく、フィルム外装電池１を確実に固定することができる。   However, as described above, in the storage case 10 of the present embodiment, the dividing line 40, that is, the mating surface of the storage member 10a is not formed in the corner portion 20. For this reason, the film filling battery 1 can be reliably fixed without the filler 31 filled in the filling portion 30 of the corner portion 20 leaking.

また、本実施形態の収納部材１０ａは、図８に示すように隅部２０が一体的に形成されているため、隅部に合わせ面を有する構成に比べて高い剛性を得ることができる。   Moreover, since the corner | angular part 20 is integrally formed as shown in FIG. 8, the storage member 10a of this embodiment can obtain high rigidity compared with the structure which has a mating surface in a corner.

また、本実施形態の収納ケース１０を構成する２つの収納部材１０ａはいずれも同一形状である。このため、一つの型で収納部材を成形することができ、コストを低減させることができる。

The intermediate portion 13 is provided at an intermediate position between the first side portion 11 and the second side portion 12. The intermediate portion 13 is formed with an exhaust gas opening 17 for discharging the gas discharged from the gas discharge portion 8 of the film-clad battery 1 to the outside of the case.
Is provided in the heat-sealing part 7a.
[Connection]
The connecting portions 14 and 15 connect the first side portion 11 and the intermediate portion 13, and also connect the intermediate portion 13 and the second side portion 12.

接続部１４の断面形状はコ字形状であり、枠形状の収納部材１０ａの長辺部分を構成するとともに、収納部材１０の長辺部分を構成する。接続部１４内にはフィルム外装電池１の熱融着部７ａが収納される。   The cross-sectional shape of the connecting portion 14 is a U-shape, and constitutes the long side portion of the frame-shaped storage member 10a and the long side portion of the storage member 10. In the connection part 14, the heat sealing | fusion part 7a of the film-clad battery 1 is accommodated.

接続部１５は平行な２枚の平板によって構成されており、フィルム外装電池１を収納部材１０ａ内に収納するための開口１６を形成している。
［収納ケース］
収納ケース１０は、一方の収納部材１０ａに対して他方の収納部材１０ａを図１中Ｚ軸周りに反転させ、これらを接合することで収納ケース１０が構成される。 The connecting portion 15 is composed of two parallel flat plates, and forms an opening 16 for storing the film-clad battery 1 in the storage member 10a.
[Storage case]
The storage case 10 is configured by reversing the other storage member 10a around the Z axis in FIG. 1 with respect to one storage member 10a and joining them together.

まず、一方の収納部材１０ａに対して図１中Ｚ軸周りに反転させた他方の収納部材１０ａを互いに対向面１１ｄが向き合うようにして向かい合わせる。次いで、一方の収納部材１０ａの係合部１１ｃ1、１１ｃ2を他方の収納部材１０ａの開口１６に差し込み、係合爪１１ｅが係合穴１２ｅに引っかかるまで挿入する。この際、他方の収納部材１０ａの係合部１１ｃ1、１１ｃ2も一方の収納部材１０ａの開口１６に差し込まれ、他方の係合爪１１ｅが一方の係合穴１２ｅに引っ掛けられる。 First, the other storage member 10a reversed around the Z axis in FIG. 1 is opposed to one storage member 10a so that the opposing surfaces 11d face each other. Next, the engaging portions 11c 1 and 11c 2 of the one storage member 10a are inserted into the opening 16 of the other storage member 10a and inserted until the engagement claw 11e is caught in the engagement hole 12e. At this time, the engaging portions 11c 1 and 11c 2 of the other storage member 10a are also inserted into the opening 16 of the one storage member 10a, and the other engagement claw 11e is hooked in the one engagement hole 12e.

以上のようにして、収納部材１０ａ同士を付き合わせて、互いの係合爪１１ｅと係合穴１２ｅとを係合させることで収納ケース１０が構成されることとなる。なお、係合穴１２ｅに対する係合爪１１ｅの係合を解除することで収納部材１０ａ同士の接合は解除される。このように本実施形態の収納ケース１０は収納部材１０ａ同士を接着剤等により固定しているわけではないので、係合爪１１ｅと係合穴１２ｅの係合を解除することで収納ケース１０内に収納されたフィルム外装電池１を取り出すことができる。   As described above, the storage case 10 is configured by attaching the storage members 10a to each other and engaging the engagement claws 11e with the engagement holes 12e. Note that the engagement of the storage members 10a is released by releasing the engagement of the engagement claws 11e with respect to the engagement holes 12e. As described above, the storage case 10 of the present embodiment does not necessarily fix the storage members 10a to each other with an adhesive or the like, so that the engagement between the engagement claw 11e and the engagement hole 12e can be released. The film-clad battery 1 housed in can be taken out.

なお、上述した実施形態では、２つの収納部材１０ａがフィルム外装電池１の長手方向両側から挟み込むようにして電池を収納する例を示したが本願発明はこれに限定されるものではない。すなわち、隅部２０に収納部材の合わせ面が形成されることによって充填剤が漏洩しなければ、収納ケースがどのように分割されるものであってもよい。   In the above-described embodiment, an example is shown in which the battery is stored so that the two storage members 10a are sandwiched from both sides in the longitudinal direction of the film-clad battery 1, but the present invention is not limited to this. That is, the storage case may be divided in any way as long as the filler does not leak by forming the mating surface of the storage member at the corner 20.

また、本実施形態のフィルム外装電池１はガス排出部８が設けられているため、収納部材１０aの中間部１３には排ガス用開口部１７が形成されている。よって、２つの収納部材１０ａを同一形状とする場合は、フィルム外装電池１のガス排出部８が設けられていない側を収納する収納部材１０ａにも排ガス用開口部１７が設けられている構成とする。これとは逆にフィルム外装電池１にガス排出部８が設けられていない場合はいずれの収納部材１０ａにも排ガス用開口部１７を設ける必要はない。   Moreover, since the film-clad battery 1 of this embodiment is provided with the gas discharge part 8, the opening part 17 for waste gas is formed in the intermediate part 13 of the accommodating member 10a. Therefore, when the two storage members 10a have the same shape, the storage member 10a that stores the side where the gas discharge portion 8 of the film-clad battery 1 is not provided is also provided with the exhaust gas opening 17. To do. On the contrary, when the gas discharge part 8 is not provided in the film-clad battery 1, it is not necessary to provide the exhaust gas opening part 17 in any of the storage members 10a.
