Description

本発明は、発電要素をアルミラミネートシート等のフレキシブルシートで覆った電池を複数個組み合わせた組電池に関するものである。   The present invention relates to an assembled battery in which a plurality of batteries in which a power generation element is covered with a flexible sheet such as an aluminum laminate sheet are combined.

携帯用電子機器等では、発電要素をアルミラミネートシートで覆うことにより薄型軽量化を図った電池が従来から使用されている。アルミラミネートシートは、樹脂シートとアルミニウム箔をラミネート状にしたフレキシブルなシート材であり、扁平状の発電要素をこのアルミラミネートシートの間に収納し、このアルミラミネートシートが重なり合った周縁部分等を両側から加熱して熱溶着させることにより内部を密閉する。また、この際、発電要素の電極に接続された金属箔からなる端子を予めアルミラミネートシートが重なり合う間を通して外部まで伸ばしておき、熱溶着によってこの端子も封止して外部に引き出されるようにしている。   In portable electronic devices and the like, batteries that have been made thin and light by covering a power generation element with an aluminum laminate sheet have been conventionally used. The aluminum laminate sheet is a flexible sheet material in which a resin sheet and aluminum foil are laminated. A flat power generation element is housed between the aluminum laminate sheets, and the peripheral portions where the aluminum laminate sheets overlap are placed on both sides. The inside is sealed by heating and heat welding. Also, at this time, a terminal made of a metal foil connected to the electrode of the power generation element is extended to the outside in advance while the aluminum laminate sheets are overlapped, and this terminal is also sealed and drawn out by heat welding. Yes.

上記のようなフレキシブルなアルミラミネートシートで覆われた電池は、外部からの圧迫によって発電要素が容易に変形破損するおそれがあるので、さらに剛性のある電池ケースの内部に収容して保護することが多い（例えば、特許文献１，２参照。）。しかしながら、このように電池を電池ケースに収容すると、外部から振動や衝撃を受けたときに、この電池ケースの内部で電池がずれたり移動するので、金属箔からなる端子に曲げや折れが生じて破損するおそれがある。そこで、特許文献１では、電池のアルミラミネートシートを電池ケースに接着することにより、端子に曲げや折れが生じないようにしている。また、特許文献２では、アルミラミネートシートの周縁の溶着部を全周にわたって電池ケースで挟持することにより、端子もこのアルミラミネートシートの間に挟み込んで固定するようにしている。   Batteries covered with a flexible aluminum laminate sheet as described above may be easily deformed and damaged by external pressure, so that they can be protected by being housed in a rigid battery case. Many (see, for example, Patent Documents 1 and 2). However, when the battery is housed in the battery case in this way, when the battery is subjected to vibration or impact from the outside, the battery is displaced or moved inside the battery case, so that the terminal made of metal foil is bent or bent. There is a risk of damage. Therefore, in Patent Document 1, the aluminum laminate sheet of the battery is bonded to the battery case so that the terminal is not bent or bent. Moreover, in patent document 2, the terminal is also pinched | interposed and fixed between this aluminum laminate sheets by clamping the welding part of the periphery of an aluminum laminate sheet with a battery case over the perimeter.

ところが、上記電池を複数個組電池ケースに収容して組電池として用いる場合にも、振動や衝撃を受けると、これらの電池が個々に組電池ケースの内部でずれたり移動するので、この組電池ケースの内部で相互に接続された各電池の端子が破損するおそれが生じるという問題があった。しかも、このような組電池では、特許文献１の場合のように、各電池のアルミラミネートシートをそれぞれ組電池ケースに接着して確実に固定することはできず、特許文献２の場合のように、この組電池ケースによって各電池のアルミラミネートシートの周縁の溶着部をそれぞれ挟持して固定することもできない。   However, even when a plurality of batteries are housed in an assembled battery case and used as an assembled battery, when the battery is subjected to vibration or impact, these batteries are individually displaced or moved inside the assembled battery case. There was a problem that the terminals of the batteries connected to each other inside the case might be damaged. Moreover, in such an assembled battery, the aluminum laminate sheet of each battery cannot be bonded and securely fixed to the assembled battery case as in the case of Patent Document 1, and as in the case of Patent Document 2. In addition, the assembled battery case cannot sandwich and fix the welded portions on the periphery of the aluminum laminate sheet of each battery.

また、上記電池をそれぞれ一対の枠体の間に挟んだものを複数個並べて固定して組電池として用いるものも従来から提案されていた（例えば、特許文献３参照。）。しかしながら、このような組電池も、一対の枠体は、アルミラミネートシートが内部の発電要素によって膨らんだ部分を挟持するものであり、このアルミラミネートシートの間から引き出される端子の部分を挟持するものではないため、外部の振動や衝撃によってこの端子がアルミラミネートシートの周縁の溶着部と共に自由振動を起こし、これの繰り返しによって破損するのを防止することはできなかった。
特開平１１−１１１２５０号公報 特開２０００−４８７７３号公報 特開２００２−３１９３８３号公報 In addition, a battery that is used as an assembled battery by arranging a plurality of batteries sandwiched between a pair of frames and fixing them has been proposed (see, for example, Patent Document 3). However, in such an assembled battery, the pair of frames sandwich the portion where the aluminum laminate sheet is swollen by the power generation element inside, and sandwich the portion of the terminal drawn out between the aluminum laminate sheets. Therefore, it was not possible to prevent the terminal from causing free vibration together with the welded portion on the peripheral edge of the aluminum laminate sheet due to external vibration or impact, and being damaged due to repetition of this.

本発明は、フレキシブルシートの間に発電要素を収納した電池を複数個組み合わせた組電池の場合に、各電池のフレキシブルシートの封止固着部から引き出される端子を確実に固定することが困難であるために、この端子が破損し易いという問題を解決しようとするものである。   In the case of an assembled battery in which a plurality of batteries each containing a power generation element are combined between flexible sheets, it is difficult to securely fix the terminals drawn from the sealing and fixing portions of the flexible sheets of the respective batteries. Therefore, an object is to solve the problem that this terminal is easily damaged.

請求項１の発明は、フレキシブルシートよりなる発電要素収納手段の封止固着部から端子を引き出した電池を複数個組み合わせた組電池において、各電池間及びこれらの電池の並びの両端に枠体が配置されると共に、各電池の両側の枠体が前記封止固着部を両側から挟持していることを特徴とする。   The invention of claim 1 is an assembled battery in which a plurality of batteries each having a terminal drawn out from a sealing and fixing portion of a power generating element housing means made of a flexible sheet are combined, and a frame is provided between each battery and at both ends of the array of these batteries. It is arranged, and the frame on both sides of each battery sandwiches the sealing adhering part from both sides.

請求項２の発明は、上記枠体が各電池ごとに両側に一対配置され、これらの電池と一対の枠体とからなるユニットが複数並べて配置されたことを特徴とする。   The invention of claim 2 is characterized in that a pair of the frame bodies are arranged on both sides for each battery, and a plurality of units each composed of these batteries and a pair of frame bodies are arranged side by side.

請求項３の発明は、上記各電池間の枠体に端子接続用導体が取り付けられると共に、この端子接続用導体に、両側の電池の端子が接続固定されたことを特徴とする。   The invention of claim 3 is characterized in that a terminal connecting conductor is attached to the frame between the batteries, and the terminals of the batteries on both sides are connected and fixed to the terminal connecting conductor.

請求項４の発明は、上記枠体が並び方向に隣接するもの同士で係止手段により互いに係止されたものであることを特徴とする。   The invention according to claim 4 is characterized in that the frame bodies adjacent to each other in the arrangement direction are locked to each other by locking means.

請求項１の発明によれば、各電池の両側の枠体が端子の引き出されたフレキシブルシートの封止固着部を両側から挟持するので、外部から振動や衝撃を受けても、この端子がフレキシブルシートの端部と共に自由振動を起こすようなことがなくなり、この振動の繰り返しにより破損するのを防止することができるようになる。しかも、例えば枠体同士が係止されていたり枠体全体が組電池ケース等に支持固定されていれば、個々の電池のずれや移動により端子が破損するのを防止することもできるようになる。   According to the first aspect of the present invention, since the frame bodies on both sides of each battery sandwich the sealing and fixing portions of the flexible sheet from which the terminals are drawn out from both sides, the terminals are flexible even when subjected to vibrations or shocks from the outside. Free vibration is not caused together with the end portion of the sheet, and breakage due to repetition of this vibration can be prevented. Moreover, for example, if the frames are locked or the entire frame is supported and fixed to the assembled battery case or the like, it is possible to prevent the terminals from being damaged due to the displacement or movement of individual batteries. .

請求項２の発明によれば、事前に各電池ごとに一対の枠体を取り付けてユニットにしておくことができるので、組電池を組み立てる際に、このユニットを複数個組み合わせればよく、それぞれバラバラな個々の電池と個々の枠体をその場で組み合わせる必要がなくなり、作業を容易にすることができるようになる。なお、この請求項２の場合には、各電池の間に枠体が２個ずつ配置されることになる。   According to the invention of claim 2, since a pair of frame bodies can be attached to each battery in advance to form a unit, when assembling the assembled battery, a plurality of these units may be combined. This eliminates the need to combine individual batteries and individual frames on the spot, thereby facilitating the work. In addition, in the case of this Claim 2, two frames are arrange | positioned between each battery.

請求項３の発明によれば、各電池の端子が、隣接して並ぶ別の電池との間の枠体に取り付けられた端子接続用導体を介して接続されるので、この端子がフレキシブルシートの封止固着部から先も含めて全て枠体によって支持されるようになり、外部から振動や衝撃に対してさらに確実に保護することができるようになる。ここで、各電池間に枠体が２個ある場合には、いずれか一方の枠体にのみ端子接続用導体を固着してもよいし、双方に端子接続用導体を固着して、組み立て後にこれらの端子接続用導体同士を接続するようにしてもよい。ただし、端子接続用導体同士を接続する場合には、各電池間の２個の枠体は、外部から振動や衝撃を受けても、相互にずれたり移動することがないようにする必要がある。   According to invention of Claim 3, since the terminal of each battery is connected via the terminal connection conductor attached to the frame between another battery which adjoins adjacently, this terminal is a flexible sheet | seat. The entire structure including the tip from the sealing and fixing portion is supported by the frame body, so that it can be more reliably protected from vibration and impact from the outside. Here, when there are two frames between the batteries, the terminal connection conductor may be fixed to only one of the frames, or the terminal connection conductor is fixed to both of the frames, and after assembly. You may make it connect these terminal connection conductors. However, when connecting the terminal connecting conductors, it is necessary that the two frames between the batteries do not shift or move from each other even when subjected to vibration or impact from the outside. .

請求項４の発明によれば、各枠体が互いに係止されるので、外部から振動や衝撃を受けても、枠体間でずれたり移動するようなことがなくなり、この枠体間のずれや移動によって端子が破損するのを防止することができるようになる。   According to the invention of claim 4, since each frame is locked to each other, even if it receives vibration or impact from the outside, it does not shift or move between the frames. It becomes possible to prevent the terminal from being damaged by the movement.

以下、本発明の最良の実施形態について説明する。   Hereinafter, the best embodiment of the present invention will be described.

本実施形態では、図１に示す非水電解質二次電池１を複数個組み合わせた組電池について説明する。この非水電解質二次電池１は、発電要素をアルミラミネートシート１１で覆ったものである。発電要素は、円筒形に巻回したものを側面から押し潰して扁平状の長円筒形に成形した巻回型のものを用いる。ただし、この発電要素の構成は任意であり、最初から長円筒形に巻回したものや積層型のものを用いることもできる。アルミラミネートシート１１は、ＰＥＴ（ポリエチレンテレフタレート）等の樹脂シートとＰＥ（ポリエチレン）等の樹脂シートとの間にアルミニウム箔を挟んでラミネート状としたフレキシブルシートであり、表面のＰＥＴ層により強度を確保すると共に、中間層のアルミニウム箔によりガスや水分、非水電解液のバリア性を確保し、内面のＰＥ層により熱溶着を容易にしている。   In the present embodiment, an assembled battery in which a plurality of nonaqueous electrolyte secondary batteries 1 shown in FIG. 1 are combined will be described. In this nonaqueous electrolyte secondary battery 1, a power generation element is covered with an aluminum laminate sheet 11. As the power generation element, a wound element is used in which a cylindrically wound element is crushed from the side surface and formed into a flat long cylindrical shape. However, the configuration of the power generation element is arbitrary, and a configuration in which the power generation element is wound in a long cylindrical shape from the beginning or a stacked type can also be used. The aluminum laminate sheet 11 is a flexible sheet laminated with an aluminum foil sandwiched between a resin sheet such as PET (polyethylene terephthalate) and a resin sheet such as PE (polyethylene), and the surface PET layer ensures strength. In addition, the barrier property of gas, moisture, and non-aqueous electrolyte is ensured by the aluminum foil of the intermediate layer, and thermal welding is facilitated by the PE layer on the inner surface.

上記発電要素は、上下２枚のアルミラミネートシート１１の間に挟んで収納される。そして、これらのアルミラミネートシート１１は、四方の周縁部をＰＥ層が合わさるようにして重ね合わせられ、上下両側から加熱押圧して熱溶着させることにより全周にわたって熱溶着部１１ａ〜１１ｄを形成し内部を密閉する。また、この際には、発電要素の電極に接続された金属箔からなる端子１２を予めアルミラミネートシート１１が重なり合う間を通して外部まで伸ばしておき、熱溶着によってこの端子１２を共に封止することにより外部に引き出されるようにしている。即ち、図１では、発電要素を上下から挟んだアルミラミネートシート１１の手前側の周縁の熱溶着部１１ａから端子１２が引き出されると共に、奥側の周縁の熱溶着部１１ｃからも逆極性の端子１２が引き出されている。なお、これらの熱溶着部１１ａ，１１ｃにおける端子１２とアルミラミネートシート１１のＰＥ層との間には、予め金属にもＰＥにも馴染み易い樹脂を介在させて封止を確実にしている。また、このアルミラミネートシート１１の内部には、完全に密閉する前に非水電解液が注入される。   The power generation element is accommodated between two upper and lower aluminum laminate sheets 11. And these aluminum laminate sheets 11 are piled up so that the PE layers are aligned on the four sides, and heat welded portions 11a to 11d are formed over the entire circumference by heating and pressing from both upper and lower sides. Seal the inside. In this case, the terminal 12 made of a metal foil connected to the electrode of the power generation element is extended to the outside in advance while the aluminum laminate sheet 11 overlaps, and the terminal 12 is sealed together by heat welding. It is pulled out to the outside. That is, in FIG. 1, the terminal 12 is pulled out from the thermal welding portion 11a on the front side of the aluminum laminate sheet 11 with the power generation element sandwiched from above and below, and the terminal having the opposite polarity is also connected from the thermal welding portion 11c on the back side 12 is pulled out. In addition, between these terminals 12a and 11c in the heat welded portions 11a and 11c and the PE layer of the aluminum laminate sheet 11, a resin that is familiar to both metal and PE is interposed in advance to ensure sealing. In addition, a nonaqueous electrolytic solution is injected into the aluminum laminate sheet 11 before being completely sealed.

上記のように構成された非水電解質二次電池１は、上下の両側から枠体２に挟み込まれる。上方の枠体２は、非水電解質二次電池１の上側のアルミラミネートシート１１における発電要素による上方への膨らみ部分の四方の周囲を囲むように配置された４本の桟２１〜２４からなる樹脂成形品である。従って、この枠体２は、非水電解質二次電池１のアルミラミネートシート１１における四方の周縁部の熱溶着部１１ａ〜１１ｄの上に各桟２１〜２４が載置される。そして、これらの桟２１〜２４は、アルミラミネートシート１１の上方への膨らみ部分の高さよりも僅かに高く形成されているので、この膨らみ部分の四方の周囲を完全に覆うことになる。また、この枠体２には、手前側の桟２１と奥側の桟２３の両端部の下端にそれぞれ下方に突出する係止凸部２ａが形成されると共に、これらの桟２１，２３の両端部の上部にも、それぞれこの係止凸部２ａが嵌まり込むようになった係止凹部２ｂが形成されている。   The non-aqueous electrolyte secondary battery 1 configured as described above is sandwiched between the upper and lower sides of the frame body 2. The upper frame 2 is composed of four bars 21 to 24 arranged so as to surround the periphery of the four sides of the upward bulging portion by the power generation element in the upper aluminum laminate sheet 11 of the nonaqueous electrolyte secondary battery 1. It is a resin molded product. Accordingly, in the frame body 2, the crosspieces 21 to 24 are placed on the heat-welded portions 11 a to 11 d on the four peripheral edges of the aluminum laminate sheet 11 of the nonaqueous electrolyte secondary battery 1. And since these crosspieces 21-24 are formed slightly higher than the height of the upward bulging portion of the aluminum laminate sheet 11, the four sides of the bulging portion are completely covered. The frame 2 is formed with locking projections 2a projecting downward at the lower ends of both ends of the front beam 21 and the rear beam 23, and both ends of these beams 21, 23. A locking recess 2b in which the locking projection 2a is fitted is formed at the top of the portion.

下方の枠体２は、上記上方の枠体２と全く同じ構成の同一部品が用いられる。従って、この下方の枠体２は、非水電解質二次電池１のアルミラミネートシート１１における四方の周縁部の熱溶着部１１ａ〜１１ｄの下に各桟２１〜２４が載置される。また、上方の枠体２の各係止凸部２ａが下方の枠体２の各係止凹部２ｂに嵌まり込み係止されるので、これら上下の枠体２は、四方の各桟２１〜２４の間に非水電解質二次電池１のアルミラミネートシート１１の周縁部の熱溶着部１１ａ〜１１ｄを挟持した状態で一体化される。なお、図１では、この係止凸部２ａが単に係止凹部２ｂに嵌まり込むことにより係止される場合を示しているが、この係止凸部２ａが係止凹部２ｂに嵌まり込むと共に例えば弾性によって噛み合って容易には外れないように係止されるものであってもよい。このようにして非水電解質二次電池１が上下一対の枠体２に挟持されると、手前側と奥側の上下の桟２１，２３に挟持されたアルミラミネートシート１１の熱溶着部１１ａ，１１ｃから引き出された端子１２は、それぞれこの一対の枠体２からも手前側と奥側に突出することになる。また、右側と左側の熱溶着部１１ｂ，１１ｄも、上下の桟２２，２４に挟持されると共に、先端部がはみ出すので、このはみ出し部分が邪魔にならないように下方に折り曲げている。   For the lower frame 2, the same parts having the same configuration as the upper frame 2 are used. Accordingly, in the lower frame 2, the crosspieces 21 to 24 are placed under the heat-welded portions 11 a to 11 d at the four peripheral edges of the aluminum laminate sheet 11 of the nonaqueous electrolyte secondary battery 1. Moreover, since each latching convex part 2a of the upper frame 2 fits and is latched in each latching recessed part 2b of the lower frame 2, these upper and lower frames 2 are attached to each of the four crosspieces 21 to 21. 24, the heat welded portions 11a to 11d at the peripheral edge portion of the aluminum laminate sheet 11 of the nonaqueous electrolyte secondary battery 1 are integrated. FIG. 1 shows a case where the locking projection 2a is locked by simply fitting into the locking recess 2b, but the locking projection 2a is fitted into the locking recess 2b. In addition, for example, they may be engaged by elasticity and locked so as not to be easily detached. When the nonaqueous electrolyte secondary battery 1 is sandwiched between the upper and lower pair of frames 2 in this way, the heat-welded portions 11a of the aluminum laminate sheet 11 sandwiched between the upper and lower bars 21 and 23 on the near side and the far side. The terminals 12 drawn out from 11c protrude from the pair of frames 2 to the near side and the far side, respectively. Also, the right and left heat welded portions 11b and 11d are also sandwiched between the upper and lower crosspieces 22 and 24, and the tip ends protrude, so that the protruding portion is bent downward so as not to get in the way.

上記のようにして非水電解質二次電池１が上下一対の枠体２に挟持されて一体化されると、図２に示すように、このような非水電解質二次電池１と一対の枠体２とからなるユニットが複数個上下に積み重ねられる。この際、上方の非水電解質二次電池１の下側の枠体２の各係止凸部２ａが下方の非水電解質二次電池１の上側の枠体２の各係止凹部２ｂに嵌まり込んで係止されるので、上下に積層された全ての枠体２が一体化される。また、各ユニット間では、それぞれの一対の枠体２から突出した端子１２同士が超音波溶接やスポット溶接により接続されて組電池が構成される。そして、このように構成された組電池は、枠状や箱状又は袋状等の適宜な組電池ケースに収容されて使用される。   When the nonaqueous electrolyte secondary battery 1 is sandwiched and integrated with the pair of upper and lower frames 2 as described above, as shown in FIG. 2, such a nonaqueous electrolyte secondary battery 1 and a pair of frames are provided. A plurality of units composed of the body 2 are stacked one above the other. At this time, each locking projection 2a of the lower frame 2 of the upper nonaqueous electrolyte secondary battery 1 is fitted into each locking recess 2b of the upper frame 2 of the lower nonaqueous electrolyte secondary battery 1. Since it is stuck and locked, all the frame bodies 2 laminated | stacked up and down are integrated. Moreover, between each unit, the terminal 12 protruded from each pair of frame 2 is connected by ultrasonic welding or spot welding, and an assembled battery is comprised. And the assembled battery comprised in this way is accommodated and used for suitable assembled battery cases, such as a frame shape, a box shape, or a bag shape.

上記構成の組電池によれば、各非水電解質二次電池１の端子１２がアルミラミネートシート１１の熱溶着部１１ａ，１１ｃで一対の枠体２の桟２１，２３によって上下から挟持されるので、外部から振動や衝撃を受けても自由振動を起こすようなことがなくなり、この振動の繰り返しによって破損するのを防止することができる。また、各枠体２間は、係止凸部２ａと係止凹部２ｂとによって係止されるので、一対の枠体２間だけでなくユニット間でもずれや移動が生じることがなくなり、端子１２の接続部分が破損するおそれもなくなる。さらに、これらの枠体２が組電池ケース内で固定されている場合には、この組電池ケースに取り付けられた組電池端子に内部の非水電解質二次電池１の端子を接続した部分が破損するおそれもなくなる。しかも、複数の非水電解質二次電池１とこの２倍の個数の枠体２とを組電池の組み立て時にその場で組み合わせるのではなく、予め各非水電解質二次電池１ごとに一対の枠体２を取り付けてユニットとしたものを組み合わせるだけでよいので、組電池の組み立て作業を容易にすることができる。   According to the assembled battery having the above configuration, the terminal 12 of each nonaqueous electrolyte secondary battery 1 is sandwiched from above and below by the crosspieces 21 and 23 of the pair of frame bodies 2 at the heat-welded portions 11a and 11c of the aluminum laminate sheet 11. Even when subjected to vibration or impact from the outside, free vibration does not occur, and damage due to repetition of this vibration can be prevented. Further, since each frame 2 is locked by the locking projection 2a and the locking recess 2b, there is no displacement or movement between the pair of frames 2 as well as between the units. There is no risk of damage to the connecting part. Furthermore, when these frame bodies 2 are fixed in the assembled battery case, the portion where the terminal of the nonaqueous electrolyte secondary battery 1 inside is connected to the assembled battery terminal attached to the assembled battery case is damaged. There is no risk of doing so. In addition, a plurality of non-aqueous electrolyte secondary batteries 1 and twice as many frames 2 are not combined on the spot when the assembled battery is assembled, but a pair of frames are previously provided for each non-aqueous electrolyte secondary battery 1. Since it is only necessary to combine the unit 2 with the body 2 attached, the assembly work of the assembled battery can be facilitated.

なお、上記実施形態では、各非水電解質二次電池１ごとに一対の枠体２を取り付けるので、非水電解質二次電池１の間に２個の枠体２が配置される場合を示したが、図３に示すように、図１及び図２の２個の枠体２を一体形成したような背の高い枠体３を用いることもできる。この場合、各非水電解質二次電池１ごとに事前にユニットを作っておくことはできないが、複数個の非水電解質二次電池１とこれより１個少ない枠体３に上下の端の２個の背の低い枠体２を組み合わせるだけでよいので、部品点数を削減することができる。   In addition, in the said embodiment, since a pair of frame 2 was attached for every nonaqueous electrolyte secondary battery 1, the case where the two frames 2 were arrange | positioned between the nonaqueous electrolyte secondary batteries 1 was shown. However, as shown in FIG. 3, a tall frame 3 in which the two frames 2 of FIGS. 1 and 2 are integrally formed can be used. In this case, it is not possible to make a unit for each nonaqueous electrolyte secondary battery 1 in advance. However, a plurality of nonaqueous electrolyte secondary batteries 1 and a frame 3 having one less than this have two upper and lower ends 2. Since it is only necessary to combine the short frame bodies 2, the number of parts can be reduced.

また、上記実施形態では、各非水電解質二次電池１のアルミラミネートシート１１の四方の熱溶着部１１ａ〜１１ｄを全て枠体２で挟持する場合を示したが、これらの枠体２は、少なくとも端子１２が引き出される手前側と奥側の熱溶着部１１ａ，１１ｃの中央部だけを挟持すればよい。即ち、枠体２の各桟２１〜２４は、非水電解質二次電池１のアルミラミネートシート１１に当接する面が全て面一である場合を示したが、例えば右側と左側の熱溶着部１１ｂ，１１ｄの上方に配置される桟２２，２４の面は、手前側と奥側の桟２１，２３よりも後退していてもよい。さらに、上記実施形態では、アルミラミネートシート１１の手前側と奥側の双方から端子１２を引き出す場合を示したが、この端子１２の引き出し位置は任意であり、例えばアルミラミネートシート１１の手前側だけから正負双方の端子１２を共に引き出すようにすることもできる。そして、この場合には、枠体２の手前側の桟２１がこのアルミラミネートシート１１の手前側の熱溶着部１１ａだけを挟持するようにしてもよい。しかも、枠体２が挟持する部分がこのように偏っている場合には、四方の桟２１〜２４を全て設ける必要もなく、挟持する部分に応じて任意の構成とすることができる。つまり、枠体２は、アルミラミネートシート１１における少なくとも端子１２が引き出される熱溶着部を挟持するようになっていればよい。   Moreover, in the said embodiment, although the case where all the four heat-welding parts 11a-11d of the aluminum laminate sheet 11 of each nonaqueous electrolyte secondary battery 1 were clamped with the frame 2 was shown, these frames 2 are It is only necessary to hold at least the center portions of the heat welding portions 11a and 11c on the near side and the far side from which the terminal 12 is pulled out. That is, each of the crosspieces 21 to 24 of the frame body 2 shows a case where all the surfaces in contact with the aluminum laminate sheet 11 of the nonaqueous electrolyte secondary battery 1 are flush with each other. , 11d, the surfaces of the crosspieces 22 and 24 may recede from the front and back crosspieces 21 and 23. Furthermore, in the said embodiment, although the case where the terminal 12 was pulled out from both the near side and the back side of the aluminum laminate sheet 11 was shown, the drawing position of this terminal 12 is arbitrary, for example, only the near side of the aluminum laminate sheet 11 It is also possible to pull out both the positive and negative terminals 12 together. In this case, the crosspiece 21 on the front side of the frame 2 may sandwich only the thermal welding portion 11a on the front side of the aluminum laminate sheet 11. And when the part which the frame 2 clamps is biased in this way, it is not necessary to provide all the crosspieces 21-24, and it can be set as arbitrary structures according to the part clamped. That is, the frame 2 only needs to sandwich the heat welded portion from which at least the terminal 12 in the aluminum laminate sheet 11 is drawn.

また、上記実施形態では、各非水電解質二次電池１の端子１２が個別に接続される場合を示したが、図３に示すように、枠体３の手前側の桟３１の側面に端子接続用導体４を取り付け、この端子接続用導体４に上下の非水電解質二次電池１の端子１２をそれぞれ接続固定するようにしてもよい。このような端子接続用導体４を用いると、アルミラミネートシート１１の熱溶着部１１ａ，１１ｃより先に突出する端子１２も固定することができるので、外部からの振動や衝撃に対してこの端子１２をさらに確実に保護することができるようになる。即ち、アルミラミネートシート１１の熱溶着部１１ａ，１１ｃを枠体２で挟持するだけでは、さらにその先に突出する端子１２のみが外部の振動や衝撃により自由振動を起こしたり組電池ケースの内面に擦れて破損するのを避けることはできないが、この端子１２を端子接続用導体４に接続固定しておけば、このような破損を防止することができるようになる。   Moreover, in the said embodiment, although the case where the terminal 12 of each nonaqueous electrolyte secondary battery 1 was connected separately was shown, as shown in FIG. The connection conductor 4 may be attached, and the terminals 12 of the upper and lower nonaqueous electrolyte secondary batteries 1 may be connected and fixed to the terminal connection conductor 4. When such a terminal connecting conductor 4 is used, the terminal 12 protruding ahead of the heat-welded portions 11a and 11c of the aluminum laminate sheet 11 can also be fixed. Therefore, the terminal 12 is resistant to external vibration and impact. Can be more reliably protected. That is, only by sandwiching the heat-welded portions 11a and 11c of the aluminum laminate sheet 11 with the frame body 2, only the terminal 12 protruding beyond that causes free vibration due to external vibration or impact, or on the inner surface of the assembled battery case. Although it is unavoidable to be damaged by rubbing, if the terminal 12 is connected and fixed to the terminal connecting conductor 4, such damage can be prevented.

ここで、上下に積み重ねた非水電解質二次電池１を直列に接続する場合には、手前側に引き出される端子１２の極性が正負交互になるように上下の非水電解質二次電池１を配置し、各非水電解質二次電池１の間の枠体３も、端子接続用導体４を取り付ける手前側と奥側の桟３１，３３を上下方向に交互に替えればよい。また、並列に接続する場合には、端子１２の極性を同じにして、各枠体３の手前側と奥側の双方の桟３１，３３にそれぞれ端子接続用導体４を取り付ければよい。   Here, when the nonaqueous electrolyte secondary batteries 1 stacked one above the other are connected in series, the upper and lower nonaqueous electrolyte secondary batteries 1 are arranged so that the polarity of the terminal 12 drawn to the near side is alternately positive and negative. And the frame 3 between each nonaqueous electrolyte secondary battery 1 should just change the front and back crosspieces 31 and 33 which attach the terminal-connection conductor 4 to an up-down direction alternately. Moreover, when connecting in parallel, the polarity of the terminal 12 is made the same, and the terminal connecting conductor 4 may be attached to both the front and back bars 31 and 33 of each frame 3.

さらに、上記では、各非水電解質二次電池１の間に配置する１個の枠体３に端子接続用導体４を取り付ける場合を示したが、図１及び図２に示したように、各非水電解質二次電池１の間に２個の枠体２を配置する場合にも、各枠体２に端子接続用導体４を取り付けることができる。ただし、この場合には、各非水電解質二次電池１の間の２個の枠体２の端子接続用導体４間は、別途接続固定する必要がある。しかしながら、例えば各非水電解質二次電池１の間の２個の枠体２のうち１個だけに端子接続用導体４を取り付けておき、ここに上下の非水電解質二次電池１の端子１２を接続固定するようにしてもよい。また、この場合、上下いずれかの非水電解質二次電池１の端子１２と端子接続用導体４との間の距離が長くなるので、この端子接続用導体４を上下いずれかの方向にはみ出すようにすることもできる。   Furthermore, in the above, the case where the terminal connection conductor 4 is attached to one frame body 3 arranged between the nonaqueous electrolyte secondary batteries 1 is shown. As shown in FIGS. Even when two frame bodies 2 are arranged between the non-aqueous electrolyte secondary batteries 1, the terminal connection conductor 4 can be attached to each frame body 2. However, in this case, it is necessary to separately connect and fix between the terminal connecting conductors 4 of the two frame bodies 2 between the nonaqueous electrolyte secondary batteries 1. However, for example, the terminal connection conductor 4 is attached to only one of the two frames 2 between the nonaqueous electrolyte secondary batteries 1, and the terminals 12 of the upper and lower nonaqueous electrolyte secondary batteries 1 are attached here. The connection may be fixed. Further, in this case, since the distance between the terminal 12 and the terminal connecting conductor 4 of the upper or lower non-aqueous electrolyte secondary battery 1 becomes longer, the terminal connecting conductor 4 protrudes in either the upper or lower direction. It can also be.

また、上記実施形態では、各枠体２に係止凸部２ａと係止凹部２ｂを形成した場合を示したが、上下の枠体２同士が係止されるようにする係止手段であれば、このような係止凸部２ａと係止凹部２ｂの構造に限定されることはない。さらに、上記実施形態では、上下の枠体２同士が係止手段により係止される場合を示したが、このような係止手段を全く形成しなくてもよい。図３に示した枠体３も、このような係止手段を形成していないために、単に非水電解質二次電池１と交互に積み重ねるだけとなるが、これらを上下から任意の挟持手段によって全体的に挟持することにより、各非水電解質二次電池１のアルミラミネートシート１１の熱溶着部１１ａ〜１１ｄをそれぞれ挟持することができる。また、組電池ケースに収容することにより、このような挟持を行うこともできる。しかも、各枠体２や各枠体３が熱溶着部１１ａ〜１１ｄを挟持していれば、この熱溶着部１１ａ〜１１ｄを介して互いに圧接されることになるので、これらの枠体２や枠体３が相互間で容易にずれたり移動するようなこともなくなる。もっとも、図３に示した枠体３に、図１及び図２に示した枠体２のような係止凸部や係止凹部等の係止手段を形成してもよい。   Moreover, although the case where the locking projections 2a and the locking recesses 2b are formed in each frame 2 has been described in the above embodiment, the locking means for locking the upper and lower frames 2 to each other may be used. For example, it is not limited to the structure of such a latching convex part 2a and the latching recessed part 2b. Furthermore, although the case where the upper and lower frame bodies 2 are locked by the locking means has been described in the above embodiment, such locking means may not be formed at all. Since the frame 3 shown in FIG. 3 also does not form such a locking means, it is simply stacked alternately with the non-aqueous electrolyte secondary battery 1, but these are held by any clamping means from above and below. By sandwiching as a whole, the heat-welded portions 11a to 11d of the aluminum laminate sheet 11 of each non-aqueous electrolyte secondary battery 1 can be sandwiched, respectively. Moreover, such clamping can also be performed by accommodating in an assembled battery case. And if each frame 2 and each frame 3 are pinching the heat welding parts 11a-11d, they will be press-contacted with each other via these heat welding parts 11a-11d. The frames 3 are not easily displaced or moved between each other. However, locking means such as locking protrusions and locking recesses like the frame body 2 shown in FIGS. 1 and 2 may be formed on the frame body 3 shown in FIG.

また、上記実施形態では、２枚のアルミラミネートシート１１を重ね合わせた発電要素収納手段を用いる場合を示したが、例えば１枚を２つ折りにしたり、封筒のように両端部と中央部で重ね合わせるようにした間に発電要素を収納してもよく、予め袋状にしたアルミラミネートシート１１の中に発電要素を収納してもよい。そして、このようにアルミラミネートシート１１を周縁部以外の端部で重ね合わせて熱溶着する場合には、端子１２も、この周縁部以外の端部の熱溶着部から引き出すようにしてもよい。さらに、このアルミラミネートシート１１の重ね合わせ部分は、熱溶着に代えて、接着等の他の方法により封止固着することもできる。さらに、上記実施形態では、アルミラミネートシート１１よりなる発電要素収納手段を用いる場合を示したが、十分な強度とバリア性を確保し確実な封止が可能なフレキシブルシートであれば材質は任意であり、ラミネートシートでなくてもよい。   Moreover, although the case where the electric power generation element accommodation means which piled up the two aluminum laminate sheets 11 was used was shown in the said embodiment, for example, one sheet is folded in two, or it overlaps with both ends and a center part like an envelope. The power generation element may be accommodated while being combined, or the power generation element may be accommodated in the aluminum laminate sheet 11 that is formed into a bag shape in advance. When the aluminum laminate sheet 11 is overlapped and thermally welded at the end other than the peripheral portion as described above, the terminal 12 may also be pulled out from the heat welded portion at the end other than the peripheral portion. Further, the overlapped portion of the aluminum laminate sheet 11 can be sealed and fixed by other methods such as adhesion instead of heat welding. Furthermore, in the said embodiment, although the case where the electric power generation element accommodation means which consists of the aluminum laminate sheet 11 was used was shown, as long as it is a flexible sheet which can ensure sufficient strength and barrier property and can be reliably sealed, the material is arbitrary. Yes, it does not have to be a laminate sheet.

また、上記実施形態では、非水電解質二次電池１を上下の１次元方向に並べる場合を示したが、上下左右のように２次元方向や上下左右と前後のように３次元方向に並べた組電池にも同様に実施可能である。さらに、上記実施形態では、非水電解質二次電池１について示したが、本発明は電池の種類は問わない。   Moreover, in the said embodiment, although the case where the nonaqueous electrolyte secondary battery 1 was arranged in the up-and-down one-dimensional direction was shown, it arranged in the three-dimensional direction like the two-dimensional direction like up and down left and right and up and down left and right and front and back. The same can be applied to the assembled battery. Furthermore, in the said embodiment, although shown about the nonaqueous electrolyte secondary battery 1, the kind of battery does not ask | require this invention.
