Description

201222601 六、發明說明： 【發明所屬之技術領域】 本發明係關於一種外部積層構裝蓄電裝置及其製造方 法’更詳言之，係關於一種可將電池或電容器（capacitor 或condenser)等的蓄電裝置要件，藉由由外部構裝薄膜構 成的外部構裝體來容納而成的外部積層構裝蓄電裝置及其 製造方法。 【先前技術】 近年來，已使用外部積層構裝蓄電裝置（具體而言， 例如電池及電容器等）作爲行動設備或電動汽車等的電源 ，該外部積層構裝蓄電裝置係將正極板與負極板中介間隔 件來捲繞或交互地積層而構成的電池要件等之蓄電裝置要 件，與電解液一同容納於由2片外部構裝薄膜構成的外部 構裝體內而成。 在外部積層構裝蓄電裝置中，藉由過充電、或被曝曬 於高溫中，電解液會被電性分解或加熱分解，起因於此就 會在外部構裝體之內部（單元（cell)內部）發生可燃性氣體等 的氣體，藉此有時會使得外部構裝體的內部壓力上升。 於是，爲了解決如此的問題，有提出各種構成的外部 積層構裝蓄電裝置（例如’參照專利文獻1至專利文獻4) 〇 具體而言，例如在專利文獻1及專利文獻2中，有提 出一種設置有如下二個構成之安全機構等的外部積層構裝 -5- 201222601 蓄電裝置，該二個構成之安全機構爲：於外部構裝體中的 2片外部構裝薄膜的接合部之一部分形成接合力較弱的部 分（以下，也稱爲「弱接合部分」），且在外部構裝體之內 部的氣體壓力（內部壓力）已上升的情況時，使該弱接合部 分發揮作爲脫氣用安全閥之功能的構成之安全機構；以及 在構成外部構裝體的外部構裝薄膜之一部分形成薄化的部 分（以下，也稱爲「薄化部分」），且使該薄化部分發揮作 爲脫氣用安全閥之功能的構成之安全機構。 在構成如此構成的外部積層構裝蓄電裝置之安全機構 的弱接合部分及薄化部分，係當外部構裝體之內部壓力已 到達預定値時就會確實地剝離或破裂而形成有排氣口，更 且被要求在通常的使用狀態下，可確實地密閉並可確保充 分的可靠度之程度的強度。然而，從製造上的觀點來看， 要確實地形成具有如此強度的弱接合部分及薄化部分並非 易事。 再者，即使在外部構裝體之內部的氣體壓力慢慢地上 升的情況下，弱接合部分也會慢慢地被剝下，另一方面， 薄化部分會進行薄化。結果，會有：弱接合部分及薄化部 分之強度變弱、安全機構之動作壓力隨時間經過而降低的 問題。又，尤其是在薄化部分方面，在金屬薄膜被積層而 成的構成被使用作爲外部構裝薄膜的情況，也會有：恐有 該金屬薄膜與電解液因接觸而發生腐蝕之虞的問題。 又，在專利文獻3中，作爲外部積層構裝蓄電裝置， 有提出如下的構成：即形成於接合部之近邊用以連通內部 ⑧ -6 - 201222601 與外部的貫通孔，可藉由以壓接該貫通孔之孔緣部的方式 設置的閥體來進行密閉，且在外部構裝體之內部的氣體壓 力已上升的情況下使閥體變形而呈開閥狀態，藉此貫通孔 會被開放的構成。 然而，在如此構成的安全機構中，已有因閥體之壓接 力隨時間經過而降低引起閥動作壓力變動之虞。而且在外 部構裝體之溫度上升的情況，也有藉由接合部之接合力降 低發生剝離而形成有開口之虞。 再者，在專利文獻4中，作爲外部積層構裝蓄電裝置 的安全機構中，有提出如下的構成：即在形成有接合部的 區域之至少一處，有非接合部位連續於容納有蓄電裝置要 件的容納部且相對於容納部設置成河口狀，藉此可形成壓 力集中部，且在形成有該非接合部位的區域形成有藉由外 部構裝薄膜之剝離而使內部與外部連通的壓力開放部而成 的構成。 然而，在如此構成的安全機構中，由於需要在構成外 部構裝體的外部積層構裝薄膜之接合部設置形成河口狀之 非接合部位的部分，所以有很難謀求裝置小型化的問題。 (專利文獻1)日本特許第3 5 54 1 5 5號公報 (專利文獻2)日本特開2004-327046號公報 (專利文獻3)日本特開2007- 1 57678號公報 (專利文獻4)日本特許第3 859645號公報 【發明內容】 201222601 (發明所欲解決之問題） 本發明係基於以上情事而開發完成者，其第1目的係 在於提供一種外部積層構裝蓄電裝置，其係在外部構裝體 之內部（單元內部）有發生氣體的情況下，不受使用環境影 響，可將該氣體從指定部位確實地排出。 又，本發明之第2目的係在於提供一種外部積層構裝 蓄電裝置，其係在外部構裝體之內部（單元內部）有發生氣 體的情況下，不受使用環境影響，可將該氣體從指定部位 確實地排出，而且可謀求小型化。 本發明之第3目的係在於提供一種外部積層構裝蓄電 裝置的製造方法，其係可輕易地製造如上述的外部積層構 裝蓄電裝置。 (解決問題之手段） 本發明的外部積層構裝蓄電裝置，其特徵爲，具備： 外部構裝體、蓄電裝置要件、以及電解液。該外部構裝體 ，係使相互疊合而成的外部構裝薄膜，在形成於各自的外 周緣部之接合部中相互地氣密性接合：該蓄電裝置要件， 係被容納在形成於該外部構裝體的容納部內，並設置具備 有夾扼構件的夾扼機構，該夾扼構件係以夾壓前述外部構 裝體中的接合部之方式裝設，且沿著該外周緣部而延伸， 且在該夾扼構件的至少一部分形成有未夾扼部分形成部。 在本發明的外部積層構裝蓄電裝置中，較佳爲：前述 夾扼構件的未夾扼部分形成部，爲切口部或開口部。 ⑧ -8- 201222601 在本發明的外部積層構裝蓄電裝置中，較佳爲：前述 夾扼構件係具有沿著前述外部構裝薄膜之外周緣部而延伸 的環狀構造。 在本發明的外部積層構裝蓄電裝置中，較―爲：在前 述外部構裝體中的前述未夾扼部分形成部所位處之區域形 成的未夾扼部分設置有安全閥。 本發明的外部積層構裝蓄電裝置的製造方法，係用以 製造前述外部積層構裝蓄電裝置，其特徵爲，具有： 夾扼機構形成步驟，其係對於裝置本體，將具備有夾 扼構件的夾扼機構，以從相疊合的外部構裝薄膜之各自的 表面側予以夾壓之方式，設置在：位於構成該裝置本體之 外部構裝體的接合部， 其中該裝置本體，具有：使相互疊合的外部構裝薄膜 ，在形成於各自的外周緣部之接合部中相互地氣密性接合 的外部構裝體、及被容納在形成於該外部構裝體之容納部 內的蓄電裝置要件、以及電解液； 且其中該夾扼構件，是沿著該外周緣部並於至少一部 分形成有未夾扼部分形成部。 在本發明的外部積層構裝蓄電裝置的製造方法，較佳 爲：在前述夾扼機構形成步驟中，具備前述夾扼構件的夾 扼機構係沿著前述外部構裝薄膜中的外周緣部之周方向配 設。 在本發明的外部積層構裝蓄電裝置的製造方法，較佳 爲：構成前述夾扼機構的夾扼構件之未夾扼部分形成部爲 -9 - 201222601 切口部或開口部。 (發明效果） 在本發明的外部積層構裝蓄電裝置中，係設置具備有 夾扼構件的夾扼機構，該夾扼構件係以夾壓外部構裝體中 的接合部之方式形成有未夾扼部分形成部。因此，在設置 有該夾扼構件的區域中，除了未夾扼部分形成部所位處的 未夾扼部分以外，由於其餘均可藉由夾扼構件來夾扼接合 部並予以押壓，所以在容納有外部構裝體中的蓄電裝置要 件之容納部內有發生氣體的情況時，會藉由外部構裝體之 內部壓力上升而使得外部構裝體膨脹，且在接合部，雖然 應力會作用及於其內部側之全周，但是藉由該應力之作用 ，可藉由接合部之未夾扼部分選擇性地剝離而形成有開口 ，且從該開口將外部構裝體內之氣體排出至外部》 又，即使在如外部構裝體之溫度上升、或是內部壓力 慢慢地上升的使用環境下於接合部產生接合強度降低的情 況，亦可防止在接合部中的夾扼構件之未夾扼部分形成部 所位處的未夾扼部分以外的區域中，因夾扼構件之押壓作 用而形成有開口。 因而，依據本發明的外部積層構裝蓄電裝置，在外部 構裝體之內部（單元內部）有發生氣體的情況下，可不受使 用環境影#，將該氣體從指定部位確實地排出。 又，在本發明的外部積層構裝蓄電裝置中，由於在用 以排出氣體的指定部位之外部構裝體的接合部，沒有需要 ⑧ -10- 201222601 與其他區域不同的特別構造，所以可謀求小型化。 更且，在本發明的外部積層構裝蓄電裝置中，由於是 藉由在未夾扼部分所位處的區域設置安全閥，該未夾扼部 分係形成於外部構裝體中的未夾扼部分形成部所位處的區 域，使該安全閥能以藉由被夾扼構件包圍的方式設置，所 以在形成有安全閥的區域以外之區域中難以因接合部剝離 而形成有開口，故可更確實地限定形成有用以排出氣體的 開口之位置。 依據本發明的外部積層構裝蓄電裝置的製造方法，藉 由在裝置本體的外部構裝體之接合部設置具備夾扼構件的 夾扼機構，就可輕易地獲得上述的外部積層構裝蓄電裝置 【實施方式】 以下，針對本發明的實施形態加以詳細說明。 第1圖係顯示本發明外部積層構裝蓄電裝置的構成之 一例的說明用俯視圖；第2圖係第1圖的外部積層構裝蓄 電裝置之說明用側視圖；第3圖係顯示構成第1圖的外部 積層構裝蓄電裝置的裝置本體之內部構成的說明用剖視圖 〇 在該外部積層構裝蓄電裝置10中，外部構裝體20, 係在分別具有熱熔合性的長方形之上部外部構裝薄膜2 1 A 及下部外部構裝薄膜21B，相互疊合的狀態下，在形成及 於各自的外周緣部之全周的接合部22中相互地氣密性接 -11 - 201222601 合而構成。在外部構裝體20,係形成有用以容納蓄電裝置 要件11的容納部23，且在該容納部23內，一同容納有蓄 電裝置要件11與有機電解液，並藉由該外部構裝體20、 蓄電裝置要件11及有機電解液構成裝置本體l〇a。 在圖示之例中，在上部外部構裝薄膜21A中之形成容 納部23的部分，被施行擠壓加工。 在外部構裝體20之接合部22中的一邊（第1圖中爲 左邊）22a，係設置有正極用端子構件14，其一端在外部構 裝體20之內部電性連接於蓄電裝置要件11之正極集電體 12a，而其另一端從接合部22之一邊22a突出至外部。另 —方面，在與外部構裝體20之接合部22中的一邊相對向 之另一邊（第1圖中爲右邊）2 2b，係設置有負極用端子構件 15，其一端在外部構裝體20之內部電性連接於蓄電裝置 要件Π之負極集電體13a，而其另一端從接合部22之另 一邊22b突出至外部。 然後，在該外部積層構裝蓄電裝置10,係於裝置本體 l〇a上設置有夾扼構件30，該夾扼構件30係沿著外部構 裝體20中的外周緣部，且以夾壓形成於該外周緣部的接 合部22之方式延伸及於至少3邊，並藉由該夾扼構件30 來構成夾扼機構。 在圖示之例中，夾扼構件30，爲延伸及於外部構裝體 20中的外部緣部之全周的構成。 夾扼構件3 0，係具有沿著形成於構成裝置本體1 〇a之 外部構裝體20中的外周緣部之接合部22之周方向而延伸 ⑧ -12- 201222601 的環狀構造，且於其一部分形成有由切口部30a構成的 夾扼部分形成部而成，並以從上部外部構裝薄膜2 1 A側 下部外部構裝薄膜21B側夾壓外部構裝體20之接合部 的方式裝設。 藉由裝設有該夾扼構件30，可在外部構裝體20之 合部22，於其周方向之一部分、具體而言於夾扼緊構 30之切口部30a所位處的區域，形成有未被夾扼構件 夾壓安裝的未夾扼部分，並且在該夾扼構件30之切口 30a以外之部分所位處的區域，形成有夾壓安裝有夾扼 件30而成的夾扼部分。 夾扼構件30，係具有環狀構造，並且形成有切口 3〇a而成，藉此可以繞外部構裝體20之接合部22中之 當作未夾扼部分以外的部分、即被當作夾扼部分的部分 圈的方式夾壓安裝。 具體而言，夾扼構件30，係藉由具有切口部的環狀 夾固材31、31及保持材（未圖示）而構成；該夾固材31 3 1係在例如外部構裝體20之接合部22上、即構成接合 22的上部外部構裝薄膜21A及下部外部構裝薄膜21B 各自的外周緣部之表面上，以夾壓該接合部22的方式 置；該保持材係相對於中介該接合部22而相對的夾固 31、31之各個，施加壓力於夾固材31、31相互地接近 方向（第2圖中的上下方向），且藉此鎖緊中介接合部22 相對的夾固材3 1、31並用以形成被固定的狀態。 在圖之例中，配置於上部外部構裝薄膜21A及下部 未 及 22 接 件 30 部 構 部 被 之 &gt; 部 之 配 材 的 而 外 •13- 201222601 部構裝薄膜21B之各自的外周緣部之表面上的夾固材31 、31，係具有同樣的形狀，且各自的切口部係以重疊的方 式位處》 構成夾扼構件30的夾固材31，係具有其外觀形狀爲 具有切口部的環狀並沿著構成裝置本體l〇a的外部構裝體 20之接合部22之周方向而延伸的構成。 在夾固材31中，其寬度（與夾扼構件30沿著外部構 裝體20之周方向而延伸的方向正交的方向之尺寸），亦如 圖之例可爲比外部構裝體20之外周緣部的寬度（接合部22 之接合寬度）還更小，亦可爲與外部構裝體20之外周緣部 的寬度（接合部22之接合寬度）同等，更如後述的第4圖及 第5圖所示，亦可爲比外部構裝體20之外周緣部的寬度（ 接合部22之接合寬度）還更大且覆蓋接合部22的構造。 又，夾固材31，亦可爲藉由一個構成材形成而成的一 體物，亦可爲藉由複數個構成材形成而成。 夾固材31，雖然只要是即使在依保材材而被施加壓力 的狀態下仍具有不被破壞的強度則非爲被特別限定，但是 從外部積層構裝蓄電裝置10中的散熱性之觀點來看，則 較適合使用由熱傳導率高的材料（以下，亦稱爲「高熱傳 導性材料」）構成。又’從使外部積層構裝蓄電裝置1〇中 之藉由夾扼構件30而構成的夾扼構造能夠確實的觀點來 看，由於需要形成依保持材而被鎖緊的狀態，所以爲了即 使在該狀態下仍不易破損，較適合使用由如橡膠材料類等 之抗變形的材料構成。 ⑧ -14- 201222601 作爲構成夾固材31的高熱傳導性材料，例如可列 鋁、鐵、金、銀、銅、不鏽鋼等的金屬材料。此等之中 基於鋁較輕量且具有較佳的熱傳導率故而特佳。 在此，對於具有從接合部22突出至外部的正極用 子構件14及/或負極用端子構件15的構成之裝置本體1 ，使用由金屬材料構成物作爲夾固材31的情況，有必 避免夾固材31因與正極用端子構件14及負極用端子構 15接觸而產生短路。具體而言，例如有必要將夾固材 之寬度設爲比外部構裝體20之外周緣部的寬度還更小 或是有必要在正極用端子構件14及負極用端子構件15 夾固材31之間，夾入例如由聚乙烯、聚丙烯、聚醯亞 、醯胺等構成的絕緣體。 作爲構成夾固材31的橡膠材料類，係可列舉天然 膠、合成橡膠、矽氧橡膠等。 又，作爲可當作夾固材31來使用之抗變形的材料 了橡膠材料類以外，例如可列舉聚乙烯、聚丙烯、聚苯 烯、聚氯乙烯等通用樹脂類、聚碳酸酯、聚對苯二甲酸 烯酯、ABS樹脂、聚醯胺、聚醯亞胺、聚縮醛共聚合物 聚颯、聚醚醚酮、氟樹脂等的工程塑膠類等。 又，夾固材31，雖然可適當地藉由設計變更而最適 ，但是較佳爲與裝置本體l〇a之厚度同等或是同等以上 亦即與垂直於接合部22所延伸之方向的方向（2圖中的 下方向）中之從上部外部構裝薄膜21A及下部外部構裝 膜21B之各個的接合部22表面突出的突出高度同等或 舉 端 0a 要 件 3 1 &gt; 與 胺 橡

又，作爲構成蓄電裝置要件11的負極層13，係可使 用以黏結劑成形電極材料者。作爲構成負極層13的電極 材料，雖然只要是可逆地受載鋰就不被特別限定，但是例 如可列舉石墨、各種的碳材料、聚並苯（polyacene)系物質 、錫氧化物、矽氧化物等的粉末狀、粒狀的負極活物質等 ⑧ -18- 201222601 又，作爲電解液，較佳爲使用可在適當的有機溶劑中 溶解電解質者。 作爲有機溶劑的具體例，例如可列舉聚乙烯碳酸酯、 聚丙烯碳酸酯、二甲酯碳酸酯、二乙酯碳酸酯、乙腈 (acetonitrile)、乙二醇二甲醚（dimethoxyethane)等的非質 子性有機溶劑，此等可單獨使用或組合2種類以上來使用 〇 又，作爲電解質，系可使用能夠產生鋰離子者，作爲 其具體例，可列舉 Lil、 LiCI04、 LiAsF4、 LiBF4、 LiPF6 如此的外部積層構裝蓄電裝置10，係相對於裝置本體 l〇a，藉由歷經夾扼機構形成步驟即可製造，該夾扼機構 形成步驟係在構成該裝置本體10a的外部構裝體20之接 合部22’沿著該外部構裝體20之外周緣部的周方向將夾 扼構件30，以從被重疊後的上部外部構裝薄膜21A及下 部外部構裝薄膜21B之各自的表面側夾壓的方式設置。 具體而言，例如可以如下方式製造。 首先，在成爲下部外部構裝薄膜21B上的容納部23 之位置，配置連接有正極用端子構件14及負極用端子構 件15的蓄電裝置要件11，之後在蓄電裝置要件1〗上，重 疊上部外部構裝薄膜21A，且熱熔合上部外部構裝薄膜 :Π A及下部外部構裝薄膜2 1 B之外周緣部的3邊》 然後’在上部外部構裝薄膜21A及下部外部構裝薄膜 -19- 201222601 21B之間注入了電解液之後，藉由熱熔合上部外部構裝薄 膜21A及下部外部構裝薄膜21B之外周緣部的未熔合之1 邊而形成外部構裝體20，藉此就可獲得裝置本體l〇a。 接著，將接合部22形成及於如此獲得的裝置本體l〇a 之外周緣部之全周，而在構成該接合部22的上部外部構 裝薄膜21A及下部外部構裝薄膜21B之表面上，分別將夾 固材31、31，以各自的切口部在成爲未夾扼部分的位置相 重疊的方式配置，且藉由保持材來固定該夾固材31、31， 藉此可獲得具有夾扼構造的外部積層構裝蓄電裝置1〇，該 夾扼構造係藉由包含夾固材31、31及保持材的構成之夾 扼構件30在外部構裝體20中的接合部22之一部分形成 有未夾扼部分而成。 在如此的外部積層構裝蓄電裝置10中，係以夾壓外 部構裝體20中的接合部22之方式設置有夾扼構件30，且 在形成有該夾扼構件30之切口部30a所位處的未夾扼部 分的區域以外之區域中，可藉由夾扼構件30來夾扼接合 部22並予以押壓。因此，當在外部構裝體20中之容納有 蓄電裝置要件11的容納部23內發生氣體時，外部構裝體 20就會藉由外部構裝體20之內部壓力上升而膨脹，雖然 藉此會在接合部22，使應力作用及於其內部側之全周，但 是藉由該應力之作用，只有接合部22之未夾扼部分會選 擇性地剝離，藉此形成有開口，且可從該開口將外部構裝 體20內的氣體排出至外部。 又，即使在如外部構裝體20之溫度上升、或是內部 ⑧ -20- 201222601 壓力慢慢地上升的使用環境下於接合部22產生接合強度 降低的情況’亦可防止在未夾扼部分以外的區域中，因夾 扼構件30之押壓作用而形成有開口。 因而，依據外部積層構裝蓄電裝置10，在外部構裝體 20之內部（單元內部）有發生氣體的情況下，可不受使用環 境影響’將該氣體從形成有未夾扼部分而成的指定部位確 實地排出。 又，在外部積層構裝蓄電裝置10中，係將位於未夾 扼部分的接合部22，設爲具有與位於夾扼部分的接合部 22之接合寬度大致同等的接合寬度。亦即，藉由將外部構 裝體20中的接合部22之全部設爲同等的接合寬度，由於 在外部構裝體20之接合部22中，沒有必要設置具有與其 他區域不同之接合寬度的特別區域，所以可輕易進行其製 造並提高作業效率，並且可謀求小型化。此外，由於也沒 有必要在外部構裝體20事先形成用以排出氣體的開口， 所以在通常的使用狀態下可獲得充分的氣密性，故可抑制 漏液等的發生，且具有較高的可靠度。 然後，該外部積層構裝蓄電裝置1〇’係可藉由在裝置 本體l〇a中的外部構裝體20之接合部22夾壓安裝夾扼構 件30而輕易獲得。 具有如此構成之本發明的外部積層構裝蓄電裝置10 ’ 除了可適用於鋰離子電容器等的有機電解質電容器以外’ 還可適用於有機電解質電池。尤其是’由於有機電解質電 容器，比起有機電解質電池還可以充電容量小的比例瞬時 -21 - 201222601 地進行充電及放電，且具有氣體壓力變化（外部構裝體之 內部壓力變化）會隨之變大的可能性’所以將本發明的外 部積層構裝蓄電裝置適用於有機電解質電容器是很有效的 〇 以上，雖然已就本發明的實施形態加以說明，但是並 非被限定於上述實施形態，而可加上各種的變更。 例如，夾壓構件，如第4圖及第5圖所示，夾固材3 5 之剖面形狀爲Π字狀。具有如此構成之夾固材35的夾扼 構件30，係在外部構裝體20之外周緣部被夾入於由配置 於上部外部構裝薄膜21A之表面上的上部側夾固部分35a 、與配置於下部外部構裝薄膜21B之表面上的.下部側夾固 部分35b之間所形成的間隙之狀態下，可藉由保持材（未 圖示），對上部側夾固部分35a及下部側夾固部分35b之 各個施加壓力於面向外部構裝體20之外周緣部的方向（第 5圖中的上下方向）並予以固定。在該夾扼構件30中，係 在與夾固材35之正極用端子構件14及負極用端子構件15 對應的位置，形成有適合該端子構件的貫通孔，且形成在 該貫通孔插通有端子構件的狀態。 又夾扼構件，雖然是在位於外部構裝體20中的未夾 扼部分的區域形成有未夾扼部分形成部，但是該未夾扼部 分形成部，除了是如第1圖、第4圖及第6圖所示的切口 部以外，亦可爲開口部。又，未夾扼部分形成部，亦可爲 藉由未施加有夾扼力（押壓力）的區域而構成者，作爲其具 體例，例如可列舉：夾扼構件，藉由以覆蓋外部構裝體中 ⑧ -22- 201222601 的外周緣部之全周的方式配置的環狀之夾固材、與用以押 壓該夾固材並形成被固定之狀態的保持材而構成，且夾固 材之一部分的區域不被該保持構件押壓，藉由該未被押壓 的區域形成有未夾扼部分形成部而成的構成》 在此，在夾扼構件中構成未夾扼部分形成部的開口部 ，係藉由延伸於外部構裝體之外周緣部之寬度方向（接合 部寬度方向）的貫通孔而形成者。構成開口部的貫通孔之 形狀，並非被特別限定，例如亦可爲圓形狀、橢圓狀、多 角形狀等。另外，開口部的大小，只要是可形成於夾扼構 件的大小即可。 又，夾扼構件，只要是在至少一部分形成有未夾扼部 分形成部即可，亦可具有複數個未夾扼部分形成部。 更且夾扼構件，只要是沿著裝置本體之外部構裝體中 的外周緣部而延伸，則除了爲如第1、第4圖及第6圖所 示形成及於外部構裝體中的外周緣部之全周而成的構成以 外，亦可爲在外周緣部之一部分、例如沿著具有如第1、 第4圖荩第6圖所示之4個邊的外部構裝體之3個邊的外 周緣部而延伸成门字狀，且在與該3個邊以外之一邊的外 周緣部對應的區域形成有未夾扼部分形成部而成的構成。 在如此構成的外部積層構裝蓄電裝置中，係在夾扼構件之 未夾扼部分形成部所位處的一邊之外周緣部形成有未夾扼 部分，且可從該未夾扼部分選擇性地促進氣體的排出。 又’裝置本體，亦可爲在形成於外部構裝體中的未夾 扼部分形成部所位處的區域之未夾扼部分設置有安全閥而 -23- 201222601 成的構成。 第6圖係顯示本發明外部積層構裝蓄電裝置之構成的 更另一實施形態之說明用俯視圖；第7圖係顯示設置於構 成第6圖的外部積層構裝蓄電裝置的裝置本體之安全閥之 構成的說明用部分放大圖：第8圖係第7圖的說明用剖視 圖。 該外部積層構裝蓄電裝置40，係在裝置本體40a形成 有安全閥25，且除了該安全閥25設置於外部構裝體20中 的未夾扼部分、即夾扼構件30之切口部30a所位處的區 域以外，其餘均具有與第1圖的外部積層構裝蓄電裝置10 相同的構成。 在裝置本體40a，係在外部構裝體20中的上部外部構 裝薄膜21A及下部外部構裝薄膜21B之外周緣部，形成有 其一邊與容納部23連通、其另一邊由接合部22包圍之平 面矩形的非接合部位24，且在該非接合部位24之中央位 置，形成有上部外部構裝薄膜21A及下部外部構裝薄膜 21B之一部分相互地接合而成的圓環狀之密封部26，並在 該密封部26之中央位置，形成有貫通上部外部構裝薄膜 21 A的孔口部27，藉此可構成安全閥25。 在圖之例中，在非接合部位24,係在上部外部構裝薄 膜21A及下部外部構裝薄膜21B之間，夾介存在形成有具 有與密封部26之外徑同等的直徑的貫通孔43之例如由聚 醯亞胺、聚苯硫或纖維素構成的非熱熔合性薄片42，而該 非熱熔合性薄片42，係可藉由黏著劑層44例如固定在上 201222601 部外部構裝薄膜21A。 在如此地於裝置本體40a設置有安全閥而成的構成之 外部積層構裝蓄電裝置40中，由於藉由將安全閥25，形 成於如被夾扼構件30包圍的位置，則在形成有安全閥25 的區域以外之區域中就不會因接合部22剝離而形成有開 口，所以可限定形成有用以更確實地排出氣體的開口之位 置。 [實施例] 以下，雖然是針對本發明之具體的實施例加以說明， 但是本發明並非被限定於此等的實施例。 〈實施例1〉 (1)正極板的製作： 藉由在寬度200mm、厚度15 μπι之帶狀的鋁箔，藉由

[Technical Field] The present invention relates to an external laminated structure power storage device and a method of manufacturing the same. More specifically, it relates to a battery or a capacitor (capacitor or condenser) or the like. The device component is an external laminated structure power storage device and a method of manufacturing the same, which are accommodated by an external component formed of an externally mounted film. [Prior Art] In recent years, an externally stacked power storage device (specifically, for example, a battery and a capacitor) has been used as a power source for a mobile device or an electric vehicle, and the external laminated device has a positive electrode plate and a negative electrode plate. The power storage device element such as a battery element that is formed by winding or alternately laminating the intermediate spacer is housed in an external structure composed of two outer-constructed films together with the electrolytic solution. In the external laminated power storage device, the electrolyte is electrically decomposed or thermally decomposed by overcharging or being exposed to high temperatures, which is caused inside the external structure (inside the cell). When a gas such as a combustible gas is generated, the internal pressure of the external structure may increase. Then, in order to solve such a problem, an external laminated structure power storage device having various configurations is proposed (for example, 'refer to Patent Document 1 to Patent Document 4). Specifically, for example, Patent Document 1 and Patent Document 2 propose a An external laminated structure of the following two safety mechanisms, such as a safety device, is provided. The power storage device is configured such that one of the joint portions of the two outer structural films in the outer structure is formed. When the gas pressure (internal pressure) inside the outer structure has risen, the weak joint portion is used as a degassing portion when the joint force is weak (hereinafter, also referred to as "weak joint portion"). A safety mechanism that constitutes a function of the safety valve; and a thinned portion (hereinafter also referred to as a "thinned portion") formed in one of the outer structural films constituting the external assembly, and the thinned portion functions as A safety mechanism consisting of the function of a safety valve for degassing. The weak joint portion and the thinned portion of the safety mechanism constituting the external laminated structure of the power storage device configured as described above are surely peeled or broken to form an exhaust port when the internal pressure of the external assembly has reached a predetermined threshold. Furthermore, it is required to be able to be tightly sealed in a normal use state and to ensure the degree of sufficient reliability. However, from the viewpoint of manufacturing, it is not easy to form a weak joint portion and a thin portion having such strength. Further, even when the gas pressure inside the outer structure is gradually raised, the weak joint portion is gradually peeled off, and on the other hand, the thinned portion is thinned. As a result, there is a problem that the strength of the weakly joined portion and the thinned portion is weakened, and the operating pressure of the safety mechanism is lowered as time passes. Further, in particular, in the case of thinning, in the case where the metal thin film is laminated and used as the outer structural film, there is a fear that the metal thin film and the electrolytic solution are corroded by contact. . Further, in Patent Document 3, as an external laminated structure power storage device, there is proposed a configuration in which a through hole formed in the vicinity of the joint portion for communicating the inside 8 -6 - 201222601 and the outside is formed by pressing The valve body provided so as to be connected to the hole edge portion of the through hole is sealed, and when the gas pressure inside the outer structure is increased, the valve body is deformed to be in a valve opening state, whereby the through hole is Open composition. However, in the safety mechanism thus constituted, there has been a decrease in the valve operating pressure due to the decrease in the pressure contact force of the valve body with the passage of time. Further, in the case where the temperature of the outer structure is increased, there is a case where the opening is formed by the peeling force of the joint portion. Further, in Patent Document 4, as a safety mechanism for externally laminating the power storage device, there is proposed a configuration in which at least one portion of the region where the joint portion is formed has a non-joining portion continuous with the power storage device. The accommodating portion of the element is provided in a estuarine shape with respect to the accommodating portion, whereby a pressure concentrating portion can be formed, and a pressure opening portion that connects the inside and the outside by peeling of the outer structural film is formed in a region where the non-joining portion is formed. The composition of the department. However, in the safety mechanism configured as described above, since it is necessary to provide a portion in which the non-joining portion of the estuary shape is formed in the joint portion of the outer laminated structure film constituting the outer structure, it is difficult to reduce the size of the apparatus. (Patent Document 1) Japanese Patent Laid-Open Publication No. 2004-327046 (Patent Document 3) Japanese Patent Application No. 3,859,645, the disclosure of which is hereby incorporated herein by reference to the entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire When gas is generated inside the body (inside the unit), it is not affected by the use environment, and the gas can be reliably discharged from the designated portion. Further, a second object of the present invention is to provide an external laminated structure power storage device which can be used to generate a gas when it is generated inside a unit (inside a unit) without being affected by the use environment. The designated part is reliably discharged, and the size can be reduced. A third object of the present invention is to provide a method of manufacturing an external laminated structure power storage device which can easily manufacture an external laminated structure power storage device as described above. (Means for Solving the Problem) The external laminated structure power storage device according to the present invention includes an external component, a power storage device component, and an electrolytic solution. The outer structure is an outer structure film which is superposed on each other, and is airtightly joined to each other at a joint portion formed at each outer peripheral edge portion: the power storage device component is housed in the A nip mechanism including a nip member is provided in the accommodating portion of the outer structure, and the nip member is provided to sandwich the joint portion of the outer structure, and along the outer peripheral portion Extending, and forming an untrapped portion forming portion at least a portion of the jaw member. In the external laminated structure power storage device of the present invention, it is preferable that the untwisted portion forming portion of the nip member is a notch portion or an opening portion. In the external laminated structure power storage device of the present invention, it is preferable that the sandwiching member has an annular structure extending along a peripheral edge portion of the outer structural film. In the external laminated structure power storage device of the present invention, a safety valve is provided in an un-clamped portion formed in a region where the un-clamped portion forming portion is located in the external assembly. A method of manufacturing an external laminated structure power storage device according to the present invention is for manufacturing the external laminated structure power storage device, comprising: a clamping mechanism forming step for providing a clamping member to the device body; The clamping mechanism is disposed at a joint portion of the outer structure of the apparatus body, and is disposed at a joint surface of the outer structure of the apparatus body, wherein the apparatus body has: An external component film that is overlapped with each other, an external component that is hermetically joined to each other in a joint portion formed at each outer peripheral edge portion, and a power storage device that is housed in a housing portion formed in the outer component body And an electrolyte; and wherein the clamping member is formed with an un-nip portion forming portion along at least a portion of the outer peripheral portion. In the method of manufacturing an external laminated structure power storage device according to the present invention, preferably, in the step of forming the clamping mechanism, the clamping mechanism including the clamping member is along an outer peripheral edge portion of the outer structural film. It is equipped in the circumferential direction. In the method of manufacturing the external laminated structure power storage device of the present invention, it is preferable that the unfolded portion forming portion of the nip member constituting the nip mechanism is a -9 - 201222601 notch portion or an opening portion. (Effect of the Invention) In the external laminated structure power storage device of the present invention, a clamping mechanism including a clamping member is formed, and the clamping member is formed by sandwiching a joint portion in the external assembly. Part of the formation. Therefore, in the region where the jaw member is provided, except for the untrapped portion where the portion where the portion is not pinched, since the rest can be pinched by the jaw member and pressed, When a gas is generated in the housing portion of the power storage device component housed in the external component, the external component is expanded by the internal pressure of the external component, and the stress acts at the joint portion. And the entire circumference of the inner side thereof, but by the action of the stress, an opening can be formed by selectively peeling off the unfolded portion of the joint portion, and the gas in the outer assembly body is discharged to the outside from the opening Further, even when the joint strength is lowered at the joint portion in a use environment in which the temperature of the outer structure rises or the internal pressure gradually rises, the pinch member in the joint portion can be prevented from being pinched. In a region other than the un-clamped portion where the 扼 portion is formed, an opening is formed by the pressing force of the nip member. Therefore, according to the external laminated structure power storage device of the present invention, when gas is generated inside the external structure (inside the unit), the gas can be reliably discharged from the designated portion without using the environmental image #. Further, in the external laminated power storage device of the present invention, since the joint portion of the outer structure for the specified portion for exhausting the gas does not require a special structure different from the other regions, it is possible to miniaturization. Furthermore, in the external laminated structure power storage device of the present invention, since the safety valve is provided in the region where the un-clamped portion is located, the un-clamped portion is formed in the outer package. The region where the partial forming portion is located allows the safety valve to be disposed by being surrounded by the nip member, so that it is difficult to form an opening due to the detachment of the joint portion in a region other than the region in which the safety valve is formed. The position at which the opening for exhausting the gas is formed is more surely defined. According to the method of manufacturing an external laminated structure power storage device of the present invention, the above-described external laminated structure power storage device can be easily obtained by providing a clamping mechanism having a clamping member at the joint portion of the external component of the device body. [Embodiment] Hereinafter, embodiments of the present invention will be described in detail. 1 is a plan view showing an example of a configuration of an external laminated structure power storage device according to the present invention; FIG. 2 is a side view for explaining an external laminated structure power storage device of FIG. 1; and FIG. 3 is a view showing a first configuration. The internal structure of the apparatus body of the external laminated structure of the power storage device is illustrated in a cross-sectional view in the external laminated structure of the power storage device 10, and the external structure 20 is externally mounted on a rectangular upper portion having heat fusion properties. In a state in which the film 2 1 A and the lower outer-structure film 21B are superposed on each other, they are formed by airtight connection -11 - 201222601 in the joint portion 22 formed on the entire circumference of each outer peripheral edge portion. In the external component 20, a housing portion 23 for accommodating the power storage device component 11 is formed, and in the housing portion 23, the power storage device component 11 and the organic electrolyte are accommodated together, and the external component 20 is provided by the external component 20 The power storage device component 11 and the organic electrolyte constitute the device body 10a. In the illustrated example, the portion of the upper outer structure film 21A where the accommodating portion 23 is formed is subjected to extrusion processing. One of the joint portions 22 (left side in the first drawing) 22a of the outer casing 20 is provided with a terminal member 14 for a positive electrode, and one end thereof is electrically connected to the electricity storage device component 11 inside the outer casing 20 The positive electrode current collector 12a has its other end projecting from the one side 22a of the joint portion 22 to the outside. On the other hand, the other side (the right side in the first drawing) 2 2b of the joint portion 22 of the outer structure 20 is provided with the terminal member 15 for the negative electrode, and one end of the terminal member 15 is provided at the outer structure. The inside of the battery 20 is electrically connected to the negative electrode current collector 13a of the power storage device component, and the other end thereof is protruded from the other side 22b of the joint portion 22 to the outside. Then, the power storage device 10 is constructed in the external laminated layer, and the device body 10a is provided with a clamping member 30 which is along the outer peripheral edge portion of the outer structural body 20 and is sandwiched The joint portion 22 formed on the outer peripheral edge portion extends over at least three sides, and the jaw member 30 constitutes a jaw mechanism. In the illustrated example, the jaw member 30 is configured to extend over the entire circumference of the outer edge portion of the outer casing 20. The clamping member 30 has an annular structure extending 8 -12 to 201222601 along the circumferential direction of the joint portion 22 formed on the outer peripheral edge portion of the outer casing 20 constituting the apparatus body 1 〇a, and A part of the formed portion forming portion is formed by the notched portion 30a, and the joint portion of the outer structure 20 is sandwiched from the lower outer structure film 21B side of the upper outer structure film 2 1 A side. Assume. By arranging the clip member 30, the joint portion 22 of the outer structure 20 can be formed in a portion of the circumferential direction, particularly in the region where the slit portion 30a of the clip tight 30 is located. There is an un-clamped portion that is not clamped and mounted by the clamp member, and a region where the portion other than the slit 30a of the clamp member 30 is located is formed with a clamp portion in which the clamp member 30 is crimped and mounted. . The clamping member 30 has an annular configuration and is formed with a slit 3〇a, whereby it can be regarded as a portion other than the un-clamped portion of the joint portion 22 of the outer structural member 20, that is, The partial loop of the clip portion is crimped and mounted. Specifically, the jaw member 30 is constituted by the annular crimping members 31 and 31 having the notched portions and the holding member (not shown); the clip member 31 3 1 is attached to, for example, the outer body 20 The joint portion 22, that is, the outer peripheral edge portion of each of the upper outer structure film 21A and the lower outer structure film 21B constituting the joint 22 is placed so as to sandwich the joint portion 22; the retaining material is opposed to Each of the opposing clamping portions 31, 31 that mediates the joint portion 22 applies pressure to the direction in which the clamp members 31, 31 approach each other (up and down direction in FIG. 2), and thereby locks the intermediate joint portion 22 relative thereto. The clamp members 3, 31 are used to form a fixed state. In the example of the figure, the outer periphery of each of the upper outer structure film 21A and the lower part of the assembly of the lower part of the 22nd part 30 of the 22th part of the assembly is the outer circumference of the 13th - 201222601 part of the film 21B. The clamping members 31, 31 on the surface of the portion have the same shape, and the respective cutout portions are positioned in an overlapping manner. The clamping member 31 constituting the clamping member 30 has an appearance shape having a slit. The annular shape of the portion extends along the circumferential direction of the joint portion 22 of the outer casing 20 constituting the apparatus body 10a. In the unclamping material 31, the width (the dimension in the direction orthogonal to the direction in which the nip member 30 extends in the circumferential direction of the outer framing member 20) may be the outer structure 20 as shown in the figure. The width of the outer peripheral portion (joining width of the joint portion 22) is also smaller, and may be equal to the width of the outer peripheral portion of the outer casing 20 (joining width of the joint portion 22), and is also shown in Fig. 4 which will be described later. Further, as shown in Fig. 5, it may be a structure that is larger than the width of the outer peripheral portion of the outer casing 20 (the joint width of the joint portion 22) and covers the joint portion 22. Further, the unclamping material 31 may be an integral body formed of one structural material, or may be formed of a plurality of constituent materials. The tempered material 31 is not particularly limited as long as it is not damaged even when a pressure is applied depending on the material, but the heat dissipation property of the electricity storage device 10 is laminated from the outside. In view of this, it is preferable to use a material having a high thermal conductivity (hereinafter also referred to as "high thermal conductivity material"). In addition, from the viewpoint of the fact that the sandwich structure formed by the sandwiching member 30 in the externally laminated power storage device 1 is reliably formed, it is necessary to form a state in which it is locked by the holding member, so that even In this state, it is still not easily broken, and it is more suitable to use a material resistant to deformation such as a rubber material. 8 - 14 - 201222601 As the high thermal conductive material constituting the unclamping material 31, for example, a metal material such as aluminum, iron, gold, silver, copper, or stainless steel may be listed. Among them, aluminum is particularly preferred because it is lighter in weight and has a better thermal conductivity. Here, in the case of the apparatus main body 1 having the configuration of the positive electrode sub-member 14 and/or the negative electrode terminal member 15 that protrudes from the joint portion 22 to the outside, the metal material is used as the nip 31, and it is necessary to avoid The pinch material 31 is short-circuited by contact with the terminal member 14 for a positive electrode and the terminal structure 15 for a negative electrode. Specifically, for example, it is necessary to set the width of the nip material to be smaller than the width of the outer peripheral portion of the outer structure 20 or to clamp the material 31 for the positive terminal member 14 and the negative terminal member 15 . An insulator composed of, for example, polyethylene, polypropylene, polythene, decylamine or the like is sandwiched between them. Examples of the rubber material constituting the unclamping material 31 include natural rubber, synthetic rubber, and silicone rubber. In addition, as a material which is resistant to deformation which can be used as the tempered material 31, in addition to the rubber material, for example, general-purpose resins such as polyethylene, polypropylene, polyphenylene, and polyvinyl chloride, polycarbonate, and poly-pairs are mentioned. Engineering plastics such as phthalic acid ester, ABS resin, polyamine, polyimide, polyacetal copolymer, polyetheretherketone, fluororesin, etc. Further, although the tempered material 31 can be appropriately optimized by design change, it is preferably equal to or equal to the thickness of the apparatus main body 10a, that is, the direction perpendicular to the direction in which the joint portion 22 extends ( 2 in the lower direction), the protrusion height from the surface of the joint portion 22 of each of the upper outer structure film 21A and the lower outer structure film 21B is equal or the end point 0a is required to be 3 1 &gt; The thinning is -15-201222601 equal. The nip 31 has a thickness equal to or greater than the thickness of the apparatus body i 〇 a, whereby it can be borrowed. The entire structure of the apparatus body 10a on which the clamp member 31 is disposed is sandwiched by the holding member, and the sandwich structure is formed, whereby the sandwich structure can be easily formed. In the example of the figure, the nip 31 has the same height as the accommodating portion 23 in the apparatus main body i 〇 a, that is, the protruding height h protruding from the joint portion 22 in the outer peripheral film 21A of the accommodating portion 23 thickness of. Examples of the holding material constituting the jaw member 30 include a corner clamp and the like. As a preferable specific example of the holding material, a thin plate having a size larger than the vertical and horizontal dimensions of the surface of the apparatus main body 10a can be cited. The angle jig constituting the holding material may be composed of, for example, a metal plate made of iron, stainless steel, aluminum or the like, or a sheet made of a resin, and a corner jig for screwing the two sheets, and The apparatus main body 10a on which the affixing material 31 is disposed on the joint portion 22 is sandwiched by the surface side of each of the upper outer structural film 21A and the lower outer structural film 21B by covering the surface thereof with two thin plates, and The two thin plates are screwed from the outer side at the outer peripheral edge portion (a portion protruding to the outside of the device body 10a where the sandwich member 31 is disposed on the joint portion 22), whereby the clamp member 3 1 is fixed. It will be locked and formed in a state of being fixed to the apparatus body 10a. In addition, in the clamping member 30, since the clamping member 31 is an annular shape having a cutout portion, the clamping member 30 can be thereby Since the annular structure having the unfolded portion forming portion composed of the notched portion 3A is formed, the holding material 8-16-201222601 can have any configuration. The pressure applied to the pinch portion of the joint portion 22 by the jaw member 30 is preferably 0. 1 to 10 MPa, more preferably 1 to 3 MPa. As a composition outside. The upper outer structure film 21A and the lower outer structure film 21B of the structure 20 can be suitably laminated, for example, a layer of polypropylene (hereinafter referred to as "PP"), an aluminum layer, and a nylon layer from the inside. Waiting for the winner. The upper outer structure film 21A and the lower outer structure film 21B are usually 50 to 300 μm thick when a PP layer, an aluminum layer, and a nylon layer are laminated. The size of the longitudinal direction of the upper outer casing film 21 and the lower outer film 21 is appropriately selected in accordance with the size of the power storage device member 11 accommodated in the housing portion 23-. However, for example, the dimension in the longitudinal direction is 40 to 200 mm, and the dimension in the lateral direction is 60 to 300 mm. Further, it is preferable that the joint width of the joint portion 22 in the apparatus main body 10a is such that the joint width of the joint portion 22 formed in the untwisted portion is equal to the joint width of the joint portion 22 formed in the grip portion. The difference is preferably within 0·1 to 3 mm. That is, the width of the joint portion 22 is preferably equal to the entire circumference of the outer peripheral edge portion of the outer casing 20. Specifically, the joint width of the joint portion 22 is, for example, 2 to 15 mm 〇 to constitute an external laminated structure. Set. 1 0. . The storage device 11 is an electrode laminate having a plurality of positive plates and a plurality of negative plates alternately sandwiched by a sandwich spacer S, and the plurality of positive plates are laminated on the positive current collector 12a of -17-201222601, respectively. The positive electrode layer 12 is formed by interposing a conductive layer as needed, and the plurality of negative electrode plates are respectively laminated on the negative electrode current collector 13a, and the negative electrode layer 13 is formed by interposing a conductive layer as needed. On the upper surface of the electrode laminate, a lithium metal (lithium layer) 18 as a lithium ion supply source is disposed, and a lithium electrode current collector 18a is laminated on the lithium metal 18 on each of the plurality of positive electrode plates. The current collector 12a is formed with a take-out portion 16, and the take-out portions 16 are welded to each other and electrically connected to the positive electrode terminal member 14. On the other hand, the negative electrode set of each of the plurality of negative electrode plates is provided. Each of the electric bodies 13a is formed with a take-out portion 17, and is welded to each other and electrically connected to the negative electrode terminal member 15. In Fig. 3, the reference numeral 19 is a lithium electrode take-out member. Floor 12, an electrode material can be formed by adding a conductive material (for example, activated carbon, carbon brush, etc.), a binder, etc. as needed. As an electrode material constituting the positive electrode layer 12, as long as it can be reversibly loaded Lithium is not particularly limited, and examples thereof include a positive electrode of a metal oxide represented by a general formula: LixMyOz (wherein, Μ represents a metal atom, and each of x, y, and z are integers) such as LiCoO 2 , LiNi 2 , and LiFe 2 . Further, as the negative electrode layer 13 constituting the power storage device component 11, an electrode material can be formed by using a binder. As the electrode material constituting the negative electrode layer 13, the lithium material is not reversibly loaded as long as it is reversibly loaded. In particular, for example, graphite, various carbon materials, polyacene-based substances, tin oxides, cerium oxides, and the like, powdery or granular negative electrode active materials, etc., are also exemplified as 8-18-201222601. The electrolytic solution is preferably one which can dissolve the electrolyte in a suitable organic solvent. Specific examples of the organic solvent include polyvinyl carbonate and polypropylene carbonate. An aprotic organic solvent such as methyl ester carbonate, diethyl carbonate, acetonitrile or dimethoxyethane, which may be used alone or in combination of two or more types. The lithium ion can be used. Specific examples thereof include an external laminated power storage device 10 such as Lil, LiCI04, LiAsF4, LiBF4, and LiPF6, which are sandwiched with respect to the device body 10a. The mechanism forming step is performed by the joining portion 22' of the outer structure 20 constituting the apparatus body 10a along the circumferential direction of the outer peripheral portion of the outer body 20 30 is provided so as to be sandwiched from the respective surface sides of the upper outer structure film 21A and the lower outer structure film 21B which are overlapped. Specifically, it can be manufactured, for example, as follows. First, the power storage device element 11 to which the positive electrode terminal member 14 and the negative electrode terminal member 15 are connected is disposed at a position of the accommodating portion 23 on the lower outer structure film 21B, and then the upper portion is overlapped on the power storage device component 1 The film 21A is laminated, and the upper outer structure film is thermally fused: three sides of the outer peripheral portion of the ΠA and the lower outer structure film 2 1 B. Then, the film 21A and the lower outer film 19 are disposed on the upper outer portion. - After the electrolyte is injected between the 201222601 and the 21B, the external structure 20 is formed by thermally fusing the unfused side of the outer peripheral portion of the upper outer structure film 21A and the lower outer structure film 21B. The device body l〇a is obtained. Then, the joint portion 22 is formed over the entire circumference of the outer peripheral portion of the apparatus main body 10a thus obtained, and on the surface of the upper outer peripheral film 21A and the lower outer structure film 21B constituting the joint portion 22, The nip members 31 and 31 are respectively disposed such that the respective cutout portions overlap at positions where the nip portions are not nip, and the nip members 31 and 31 are fixed by the holding members, whereby the nips can be obtained. The external laminated structure of the structure is configured to be formed by one portion of the joint portion 22 in the outer structure 20 by the sandwich member 30 including the sandwich members 31 and 31 and the retaining member. Unfolded part. In the external laminated structure power storage device 10, the nip member 30 is provided so as to sandwich the joint portion 22 in the outer structure 20, and the slit portion 30a in which the nip member 30 is formed is located. In the region other than the region where the unfolded portion is located, the joint portion 22 can be pinched by the pinch member 30 and pressed. Therefore, when gas is generated in the accommodating portion 23 of the external component 20 in which the power storage device component 11 is housed, the external component 20 is expanded by the internal pressure of the external component 20, although At the joint portion 22, the stress acts on the entire circumference of the inner side thereof, but by the action of the stress, only the untrapped portion of the joint portion 22 is selectively peeled off, whereby the opening is formed and can be This opening discharges the gas in the outer package 20 to the outside. Further, even in the case where the temperature of the external assembly 20 rises or the internal 8-20-201222601 pressure gradually rises, the joint strength is lowered at the joint portion 22, the unbonded portion can be prevented. In the other region, an opening is formed by the pressing force of the jaw member 30. Therefore, when the gas storage device 10 is configured in the outer layer (the inside of the unit) according to the external laminate, the gas can be generated from the unfolded portion without being affected by the use environment. The part is discharged. Further, in the externally laminated power storage device 10, the joint portion 22 located at the unsandwich portion is formed to have a joint width substantially equal to the joint width of the joint portion 22 located at the sandwich portion.
