201212337 六、發明說明： 【發明所屬之技術領域】 本發明係關於蓄電裝置。 【先前技術】 將具備正極及負極之蓄電單元，與電解質同時收容並 封閉於外裝體內部之構造的封閉型蓄電池係大家所熟知。 封閉型蓄電池之蓄電單元，係採用介由分離器交互層合正 極及負極之形態、及介由分離器捲回正極及負極之形態。 此種蓄電單元時，藉由使層合數及捲繞數之增多’可以追 求封閉型蓄電池之高能量化、及大容量化。 上記之封閉型蓄電池，若於短時間之期間重複進行充 放電，有時會蓄積熱而成爲高溫，有時該高溫化會導致性 能的劣化。尤其是，近年來，隨著對封閉型蓄電池之高能 量化的要求，發熱量也增大。 針對此種問題，例如，日本特開2009-272048號公報 所揭示之技術，係將以層合薄膜做爲電池容器使用之封閉 型二次電池固定於金屬製之散熱板來提高散熱性。 【發明內容】 然而，隨著能量及蓄電容量之增大，充放電所伴隨之 發熱量也增大，同時，也導致蓄電池之大型化，因爲熱容 易蓄積於蓄電池內部，故必須進行比目前更有效率之散熱 -5- 201212337 本發明之數種形態的目的之一，就是提供散熱性良好 之蓄電裝置。 本發明係用以解決上述課題之至少一部分者’並可以 下述形態及適用例來實現。 〔適用例1〕 本發明之蓄電裝置之一形態，係含有：將具有正極、 負極、及電解質之蓄電單元收容於外裝體之蓄電池；配設

602之2個內面603。藉此，將蓄電池10所發生之熱’介由 散熱板30傳導至框體602 ’並從框體602進行散熱。例如’ 可藉由冷卻框體602而提高進一步提高散熱性。亦即’散 熱板30，亦具有將蓄電池1〇(蓄電單元18)所發生之熱傳 導至框體602之熱管的機能。所以’蓄電裝置600 ’可以具 有高散熱性。 其次，針對蓄電池10、端子20、22、散熱板30之構成 進行更詳細之說明。第4圖，係本實施形態之蓄電裝置600 之一部分的模式平面圖。第5圖，係本實施形態之蓄電裝 置6 00之一部分的模式圖，係從第4圖之V方向觀察時之圖 。第4圖及第5圖，爲了方便，只圖示著1個蓄電池1〇、配 設於該蓄電池10之一組正極端子20及負極端子22、以及配 設於該蓄電池10之1個散熱板30。 蓄電池10，如第4圖及第5圖所示，可以具有外裝體I2 及蓄電單元18。 外裝體12，於其內部收容著蓄電單元18。蓄電單元18 ，可以說是藉由外裝體12來進行封閉。外裝體12，具有第 1外裝膜14及第2外裝膜16。例如，亦可以熱壓接合第1外 裝膜14及第2外裝膜16來構成外裝體12。 第1外裝膜14，可以具有外裝體12之內側面之扁平內 面14a。第2外裝膜16，可以具有外裝體12之內側面之扁平 內面16a。扁平內面14a、16a，亦可接觸收容於外裝體12 內之蓄電單元18。扁平內面14a、16a，係由因爲收容蓄電 單元18所造成之外裝體12之凸出所形成之面。亦即，扁平 -12- 201212337 內面14a、16a之平面形狀，亦可以由蓄電單元18所導致之 外裝體12之凸出來決定。扁平內面14a、16a之平面形狀， 以矩形爲佳，亦可以爲正方形或長方形。第4圖所示之例 時，扁平內面14a、16a之平面形狀爲長方形。 第1外裝膜14，係外裝體12之外表面，可以爲具有與 第1外裝膜14之扁平內面14a爲相反側之面的扁平外面14b 。第2外裝膜16，係外裝體1 2之外表面，可以爲具有與第2 外裝膜16之扁平內面16 a爲相反側之面的扁平外面16b。扁 平外面14b、16b之平面形狀，也可以爲分別與扁平內面 14a、16a之平面形狀相同。扁平外面14b、16b，可謂是因 收容蓄電單元18之外裝體12之凸出所形成之面。 外裝膜14、16，例如，使用層合薄膜。層合薄膜，例 如，由金屬層、及夾持該金屬層之第1樹脂層及第2樹脂層 所構成。金屬層之材質，例如，鋁。第1樹脂層之材質， 例如，聚對苯二甲酸乙酯（PET)、聚四氟乙烯（PTFE) 、聚醯胺系樹脂。第2樹脂層之材質，例如，乙烯-醋酸乙 烯共聚物樹脂（EVA )、或聚乙烯、聚丙烯等之烯烴系樹 脂。 藉由使用此種薄膜狀之外裝膜14、16，例如，相較於 使用由金屬等所構成之硬質外裝體（金屬罐等）時，可以 追求蓄電池1 〇之小型化及輕量化。 蓄電單元18，被收容於外裝體12內。蓄電單元18，具 有正極、負極、及電解質。此外，蓄電單元18，亦可具有 用以隔離正極及負極之分離器。正極、負極、及分離器， -13- 201212337 可以具有薄片狀之形狀。蓄電單元18，亦可以爲將介由分 離器而配置之正極及負極捲回之捲回型構造。此外，蓄電 單元18，亦可以爲介由分離器交互層合正極及負極之層合 型構造。蓄電單元18，具体而言，可以鋰離子電容、鋰離 子電池、雙電層電容爲例。此外，針對用以構成蓄電單元 1 8之正極、負極、電解質、及分離器之詳細說明，如後面 所述。 蓄電池10之厚度T，應爲4mm以上、20mm以下。蓄電 池之厚度若爲前述範圍，例如，內建於蓄電池之蓄電單元 爲層合型構造時，可以增加正極及負極之層合數。此外， 內建於蓄電池之蓄電單元爲捲回型構造時，可以增加正極 及負極之捲繞數。結果，容易實現本發明意圖之能量容量 較大之蓄電裝置的構成。 爲了增大能量容量而使蓄電單元大型化，導致蓄電池 之厚度大於4mm時，因充放電而於蓄電單元之內部所發生 之熱蓄積於蓄電池內部之傾向變高，而難以有效地對外部 進行散熱。結果，蓄電池內部之溫度呈現隨著氣體發生的 程度而上昇之傾向。然而’即使爲了得到大能量而增加蓄 電池10之厚度時，藉由具備如本專利申請之具備接觸於框 體602之內面603的散熱板30，可以有效率地進行散熱。例 如，蓄電池10之厚度T爲8mm之鋰離子電容時，亦可以確 保1 000F以上之蓄電單元18的能量容量。此時，與從蓄電 單元18之大發熱量無關’本發明之蓄電裝置600時’可以 藉由散熱板30及框體6 02’有效率地將蓄電池10內部所發 -14- 201212337 生之熱散熱至外部。 此外，蓄電池10之厚度T，蓄電單元18爲捲回型構造 時，例如，係收容於外裝體12內之狀態之蓄電池1〇的厚度 。此外，蓄電單元1 8爲層合型構造時’例如’係收容於外 裝體12內之狀態之蓄電池10之層合方向的大小（長度）。 如上面所述，蓄電單元18，亦可接觸外裝膜14、16之扁平 內面14a、16a。所以，蓄電池10之厚度T，只要爲扁平外 面14b與扁平外面16b之間的距離即可。 正極端子20及負極端子22，如第5圖所示，係通過外 裝體12來配設。正極端子20及負極端子22’係在保持外裝 體1 2之密閉性之狀態，從外裝體1 2之內側延伸至外側爲止 。正極端子20及負極端子22之配置’並無特別限制。第4 圖及第5圖所示之例時，正極端子2 0係從外裝體1 2之左側 端部（一方側之端部）延伸而出，負極端子22係從外裝體 12之右側端部（另一方側之端部）延伸而出。正極端子20 ，電性連結於蓄電單元18之正極。負極端子22，電性連結 於蓄電單元18之負極。正極端子20之材質，例如，鋁。負 極端子22之材質，例如，銅、鎳。 散熱板30，如第5圖所示，係配設於外裝體12之外表 面。第5圖所示之例時，散熱板30，係以接觸扁平外面14b 來配設。圖上未標示，然而，散熱板30，亦可以接觸扁平 外面16b來配設。散熱板30，亦可以覆蓋扁平外面14b或扁 平外面16b之全面來配設。藉此，可以提高散熱性。 如第4圖所示，從平面觀察時（例如，從散熱板3 0之 -15- 201212337 厚度方向觀察時），外裝體12，例如，係配置於散熱板30 之外周之內側。亦即，平面觀察時，散熱板30之面積，大 於外裝體12之面積。藉此，可以增加散熱板30之表面積， 而可提高散熱性。此外，正極端子20及負極端子22，從平 面觀察時，係以從散熱板30之外周朝外側突出之方式配置 。藉此，可以使端子20、22及外部配線（未圖示）之連結 較爲容易，而容易從正極端子20得到電流。 散熱板30之材質，從熱傳導性之觀點而言，例如，以 鋁、鐵、銅、或以該等金屬之任一爲主要成份之合金。該 等金屬當中，以輕量化之觀點而言，又以鋁爲佳。 散熱板3 0之形狀，並無特別限制，然而，第4圖及第5 圖所示之例時，係平板狀。並未圖示，然而，散熱板30, 於其表面亦可具有凹凸。藉此，可以增加散熱板3 0之表面 積，而可提高散熱性。 散熱板30之厚度，以ΙΟμηι以上、300μιη以下爲佳， 50μιη以上、200μιη以下更佳。 散熱板30，可以進行蓄電單元18所發生之熱的散熱。 此外，散熱板30，可以將蓄電單元18所發生之熱均一地擴 散至蓄電單元18整體，而抑制局部的昇溫。例如，蓄電單 元18之中央部之發熱量大於端部之發熱量時，可藉由散熱 板30而使其發熱均一化。 將散熱板30設置於外裝體12之方法，並無特別限制， 然而，使用將散熱板30之表面與外裝體12之外表面進行接 著之方法。更具體而言，例如，可以爲使用熱壓性樹脂（ -16- 201212337 乙烯-醋酸乙烯共聚物樹脂、烯烴系樹脂等）或接著劑（ 熱熔型接著劑、濕氣硬化型接著劑、壓敏性接著劑等）之 熱傳導性筒之接著劑的接著方法。此外，藉由將氮化硼等 無機系塡料及環氧樹脂等有機系塡料混合接著劑，可以進 一步提闻熱傳導性。所以，本發明時，於散熱板3〇與外裝 體1 2之間介設此種接合劑之構成，亦包含於以使散熱板3 〇 接觸外裝體12之外表面來配設之構成例。此外，亦可進行 散熱板30及外裝體12之熱熔，亦可以爲利用冲壓法之壓接 。此外’亦可利用適當治具（未圖示），來使散熱板30與 外裝體12接觸。此外，使用接著劑時，爲了提高散熱性， 亦可以使接著劑不存在於接著面以外而只有接著面存在著 接著劑。 其次，針對蓄電池1〇之內部構造進行說明。第6圖， 係本實施形態之蓄電裝置600之一部分的剖面圖，係第5圖 所示之蓄電池10之（外裝體12之）內部構造的模式剖面圖 。此外，第6圖時，爲了方便，省略了散熱板30之圖示。 蓄電單元18，如第6圖所示，具有收容著外裝體12之 電極層合體5及電解液（未圖示）。 電極層合體5，係浸漬於電解液。電極層合體5，可以 含有正極1、負極2、分離器4。正極1、負極2、及分離器4 ，係具有薄片狀之形狀。圖示之例時，電極層合體5，係 從第2外裝膜16之扁平內面16a依序層合著負極2、正極1、 負極2、正極1、負極2，且於極與極之間、及極與外裝體 之間，介設著分離器4來構成。電極層合體5時，正極1及 -17- 201212337 負極2係分別倂聯。 此外，正極1及負極2之數目，並無特別限制。 ，電極層合體5之形態，並未受限於圖示之例，例如 正極、負極、及分離器重疊來形成層合薄片，並捲回 合薄片之捲回構造體亦可。 正極1，如第6圖所示，具有正極集電體la、及 活物質層lb。正極集電體la及正極活物質層lb， 用蓄電裝置之眾所皆知的材料。正極集電體1 a之材 例如，鋁、鎳、鈦。正極集電體1 a，亦可以爲由前

蓄電裝置700時，如第1 1圖所示，散熱板30，係接觸 於互相同之框體602之內面603 (例如，上面或下面）。亦 即，介由蓄電池10，相鄰之散熱板30當中，一方之散熱板 30，係接觸框體602之第1內面603 a (例如，上面），另一 方之散熱板30，則係接觸與框體602之第1內面603 a不同之 第2內面603b (例如，下面）。第1 1圖所示之例時，爲蓄 電池l〇a及蓄電池10b所夾之散熱板30、及爲蓄電池l〇c及 蓄電池10d所夾之散熱板30，係接觸第1內面603a。爲蓄電 池1 Ob及蓄電池1 0c所夾之散熱板30、及兩端之散熱板30, 係接觸第2內面603b。藉此，熱不會集中於框體6 02之一部 分而使熱分散至整體，故可有效地進行散熱。 此外，散熱板30，如第12圖所示’亦可接觸於框體 602之內面（側面）。亦即，散熱板30，亦可接觸於框體 602之3個內面603。藉此，可以使熱均一地傳導至框體602 〇 此外，並未圖示，然而，散熱板3〇’亦可連結著操控 -24- 201212337 單元等之冷卻機構。藉由此種形態’亦可提高蓄電裝置 7 0 〇之散熱性》 2.4、第4變形例之蓄電裝置 其次，參照圖式，針對本實施形態之第4變形例之蓄 電裝置進行說明。第13圖，係本實施形態之第4變形例之

電池l〇b之間、及蓄電池l〇c與蓄電池10d之間。蓄電裝置 800時，蓄電池l〇b及蓄電池10c，係介由空隙而以互相隔 離之方式來配設。 依據蓄電裝置800 ’例如’相較於蓄電裝置600之例’ 蓄電池10內發生氣體時，蓄電池1〇，因爲蓄電池1〇之間存 在著空隙而容易變形（膨脹）。所以，蓄電裝置8 00 ’可 以具有高信賴性。蓄電池內即使發生氣體，而蓄電池不會 發生變形時，有蓄電池之內部壓力大幅上昇而發生故障的 可能性。 2.5、第5變形例之蓄電裝置 -25- 201212337 其次’參照圖式’針對本實施形態之第5變形例之蓄 電裝置進行說明。第1 5圖，係本實施形態之第5變形例之 蓄電裝置900的模式圖’對應於第2圖。第16圖，係本實施 形態之第5變形例之蓄電裝置900的模式圖，係從第15圖之 XVI方向觀察時之圖。第17圖，係本實施形態之第5變形例

之端子20、22、及配設於該蓄電池10之固定構件40。 蓄電裝置9 00，如第15圖〜第18圖所示，具有固定構 件40。固定構件40，例如，避開散熱板30而配設於外裝體 12之外表面。亦即，固定構件40及散熱板30，並未重疊。 第17圖所示之例時，散熱板30，配設於扁平外面14b、16b 之中央部。固定構件40，係以避開扁平外面14b之中央部 ，而以從扁平外面14b至相對於與扁平外面14b爲連續之扁 平外面14b爲傾斜之傾斜外面14c爲止之方式來配設。固定 構件40，係以避開扁平外面16b之中央部，而以扁平外面 16b至相對於與扁平外面16b爲連續之扁平外面16b爲傾斜 之傾斜外面16c爲止之方式來配設。圖示之例時’固定構 件4 0，係針對1個蓄電池10配設著4個。 例如，如第1 7圖所示，可以第1外裝膜1 4側之固定構 -26- 201212337 件40 (第1固定構件40a )、及第2外裝膜16側之固定構件 40 (第2固定構件4 0b)來夾持蓄電池10，而將蓄電池10固 定於框體602內。更具體而言，第1固定構件40a，係從第1 外裝膜14之扁平外面14b配設至傾斜外面14c爲止。第2固 定構件40b，係從第2外裝膜16之扁平外面16b配設至傾斜 外面16c爲止。固定構件40，如第18圖所示，具有凸出部 42。凸出部42內，可以收容因爲收容著蓄電單元18之外裝 體12(蓄電池10)而凸出之部分（扁平外面14b、16b等） 。藉此，可以安定地固定蓄電池10。 固定構件40及外裝體12之設置方法，例如，可以利用 以熱壓性樹脂（乙烯-醋酸乙烯共聚物樹脂、烯烴系樹脂 等）及接著劑（熱熔型接著劑、濕氣硬化型接著劑、壓敏 性接著劑等）之熱傳導性高之接著劑來進行接著之方法。 此外，亦可以將氮化硼等之無機系塡料及環氧樹脂等之有 機系塡料混合至接著劑。 固定構件40，可以連結於框體6 02之內面603，而將蓄 電池10固定於框體602內。固定構件40之材質，例如，鋁 、鐵、銅、或以該等金屬之任一爲主要成份之合金。 固定構件40及框體602之連結方法，並無特別限制， 然而，例如，可以利用螺絲螺合於固定構件40之螺孔44 ( 參照第18圖），來將其固定於框體602之內面603，也可利 用熔接固定，亦可利用固定構件40及外裝體12之設置方法 所列舉之接著劑來實施。 固定構件40之剛性，亦可大於散熱板30之剛性。藉此 -27- 201212337 ，可以安定地固定蓄電池1 0。例如，如第1 9圖所示，藉由 使固定構件40之厚度大於散熱板30之厚度，來使固定構件 40之剛性大於散熱板30之剛性。此外，第15圖所示之例時 ，相鄰之蓄電池10彼此共用1個散熱板30，然而，第19圖 所示之例時，1個蓄電池10配設著2個散熱板30。 此外，第15圖及第19圖所示之例時，配設有4個蓄電 池1 〇，然而，其數目並無特別限制，例如，可以配設1個 蓄電池10，亦可配設4個以上之蓄電池10，可以依據其目 的之輸出電壓及輸出電流來適度設定其數目。 依據蓄電裝置900，利用固定構件40，可以安定地將 蓄電池10固定於框體602內。所以，蓄電裝置900，可以具 有高信賴性。 此外，蓄電裝置900時，藉由使固定構件40之厚度大 於散熱板30之厚度，可以使固定構件40之剛性大於散熱板 30之剛性。藉此，即使於蓄電池10內，因爲發生氣體而使 蓄電池1 0變形時，利用剛性較大之固定構件40可以維持蓄 電池10之安定固定，散熱板30，因爲剛性較小，故可追隨 蓄電池1 0之變形。例如，剛性較大之散熱板，無法追隨蓄 電池之變形，有時會導致蓄電池與散熱板之接觸不夠充份 。甚至導致散熱板從蓄電池剝離。所以，有時會導致散熱 性降低。依據蓄電裝置900，可以消除此種問題，而維持 蓄電池10之安定固定，故可具有高散熱性。此外，第15圖 及第17圖所示之例時，因爲固定構件40及散熱板30並未重 疊，固定構件40不會妨礙散熱板30之變形，散熱板30，可 -28- 201212337 以追隨蓄電池ι〇之變形。 此外，本發明時，「剛性」係指，對物體施加外力而 變形時，物體抵抗該變形之程度。亦即，剛性愈小，則物 體愈容易變形（容易彎曲）。 此外，蓄電裝置900，如第20圖所示，於固定構件40 與蓄電池1 〇之間，亦可存在有散熱板3 0。亦即，固定構件 40之一部分及散熱板30之一部分也可以重疊。藉此，可以 更確實地抑制散熱板從蓄電池剝離。

The external terminals 604 and 606 are arranged to extend from the inside to the outside of the frame 602. In the example shown in Fig. 2, the external terminal 604' is electrically connected to the positive terminal 20 of the battery 10a via the wiring 608. Further, the external terminal 6 0 6 ' is electrically connected to the negative terminal 22 of the battery 10 d by the wiring 6 〇 8 . The material of the external terminals 604, 606' is, for example, aluminum, copper or nickel. The heat radiating plate 30 is brought into contact with the inner surface (side surface) 603 of the frame 602 as shown in Fig. 3. In the example shown in Fig. 3, the heat sink 30' is in contact with the two inner faces 603 of the frame -11 - 201212337 602. Thereby, the heat generated by the battery 10 is conducted to the frame 602' via the heat dissipation plate 30, and heat is dissipated from the frame 602. For example, the heat dissipation can be further improved by cooling the frame 602. That is, the heat dissipation plate 30 also has a function of transferring heat generated by the battery 1 (the electric storage unit 18) to the heat pipe of the casing 602. Therefore, the power storage device 600' can have high heat dissipation. Next, the configuration of the battery 10, the terminals 20, 22, and the heat sink 30 will be described in more detail. Fig. 4 is a schematic plan view showing a part of power storage device 600 of the present embodiment. Fig. 5 is a schematic view showing a part of the power storage device 600 of the present embodiment, as viewed from the V direction of Fig. 4. 4 and 5, for convenience, only one battery 1 〇, one set of the positive electrode terminal 20 and the negative electrode terminal 22 of the battery 10, and one heat sink disposed on the battery 10 are shown. 30. As shown in FIGS. 4 and 5, the battery 10 may have an exterior body I2 and a power storage unit 18. The exterior body 12 houses the power storage unit 18 therein. The electric storage unit 18 can be said to be closed by the exterior body 12. The exterior body 12 has a first exterior film 14 and a second exterior film 16. For example, the outer casing 12 may be configured by thermocompression bonding the first outer casing film 14 and the second outer casing film 16. The first exterior film 14 may have a flat inner surface 14a on the inner side surface of the exterior body 12. The second exterior film 16 may have a flat inner surface 16a on the inner side surface of the exterior body 12. The flat inner faces 14a and 16a may also be in contact with the electric storage unit 18 housed in the outer casing 12. The flat inner faces 14a and 16a are formed by the projection of the casing 12 by the storage of the electricity storage unit 18. That is, the planar shape of the inner faces 14a, 16a of the flat -12-201212337 may be determined by the convexity of the outer casing 12 caused by the electric storage unit 18. The planar shape of the flat inner faces 14a, 16a is preferably a rectangle or a square or a rectangle. In the example shown in Fig. 4, the flat inner faces 14a and 16a have a rectangular shape in plan view. The first exterior film 14 is the outer surface of the exterior body 12, and may be a flat outer surface 14b having a surface opposite to the flat inner surface 14a of the first exterior film 14. The second exterior film 16 is an outer surface of the exterior body 1 2 and may be a flat outer surface 16b having a surface opposite to the flat inner surface 16 a of the second exterior film 16 . The planar shape of the flat outer faces 14b, 16b may be the same as the planar shape of the flat inner faces 14a, 16a, respectively. The flat outer faces 14b and 16b can be said to be formed by the projections of the package 12 outside the storage battery unit 18. For the exterior films 14, 16, for example, a laminated film is used. The laminated film is composed of, for example, a metal layer and a first resin layer and a second resin layer sandwiching the metal layer. The material of the metal layer, for example, aluminum. The material of the first resin layer is, for example, polyethylene terephthalate (PET), polytetrafluoroethylene (PTFE), or polyamine resin. The material of the second resin layer is, for example, an ethylene-vinyl acetate copolymer resin (EVA) or an olefin resin such as polyethylene or polypropylene. When the film-shaped exterior films 14 and 16 are used, for example, when a rigid outer casing (metal can or the like) made of metal or the like is used, the size and weight of the battery 1 can be reduced. The electric storage unit 18 is housed in the exterior body 12. The electric storage unit 18 has a positive electrode, a negative electrode, and an electrolyte. Further, the electric storage unit 18 may have a separator for isolating the positive electrode and the negative electrode. The positive electrode, the negative electrode, and the separator, -13- 201212337 may have a sheet-like shape. The electric storage unit 18 may be a rewind type structure in which the positive electrode and the negative electrode disposed via the separator are wound back. Further, the power storage unit 18 may have a laminated structure in which a positive electrode and a negative electrode are alternately laminated via a separator. The power storage unit 18 is specifically exemplified by a lithium ion capacitor, a lithium ion battery, and an electric double layer capacitor. Further, a detailed description of the positive electrode, the negative electrode, the electrolyte, and the separator for constituting the electricity storage unit 18 will be described later. The thickness T of the battery 10 should be 4 mm or more and 20 mm or less. When the thickness of the battery is within the above range, for example, when the electric storage unit built in the battery has a laminated structure, the number of laminations of the positive electrode and the negative electrode can be increased. Further, when the electric storage unit built in the battery is of a rewind type structure, the number of windings of the positive electrode and the negative electrode can be increased. As a result, it is easy to realize the configuration of the power storage device having a large energy capacity as intended by the present invention. In order to increase the energy capacity and increase the size of the power storage unit, the thickness of the battery is greater than 4 mm, and the heat generated in the power storage unit due to charge and discharge tends to accumulate inside the battery, which makes it difficult to efficiently dissipate the outside. . As a result, the temperature inside the battery tends to rise as the gas occurs. However, even if the thickness of the battery 10 is increased in order to obtain a large amount of energy, heat dissipation can be efficiently performed by providing the heat dissipation plate 30 having the inner surface 603 contacting the frame 602 as in the present patent application. For example, when the thickness T of the battery 10 is a lithium ion capacitor of 8 mm, the energy capacity of the power storage unit 18 of 1 000 F or more can be ensured. At this time, irrespective of the large amount of heat generated from the power storage unit 18, the power storage device 600 of the present invention can efficiently dissipate the heat generated by the internal battery 14-201212337 by the heat dissipation plate 30 and the frame 205'. To the outside. Further, when the thickness T of the battery 10 is in the winding-back type, the storage unit 18 is, for example, the thickness of the battery 1 in a state of being housed in the exterior body 12. In addition, the electric storage unit 18 is a size (length) of the lamination direction of the battery 10 in a state in which the electric storage unit 18 is placed in the outer casing 12, for example. As described above, the electric storage unit 18 can also contact the flat inner faces 14a, 16a of the exterior films 14, 16. Therefore, the thickness T of the battery 10 is only required to be the distance between the flat outer surface 14b and the flat outer surface 16b. The positive electrode terminal 20 and the negative electrode terminal 22 are disposed by the exterior body 12 as shown in Fig. 5. The positive electrode terminal 20 and the negative electrode terminal 22' are extended from the inner side to the outer side of the outer casing 1 2 while maintaining the airtightness of the outer casing 1 2 . The arrangement of the positive electrode terminal 20 and the negative electrode terminal 22 is not particularly limited. In the example shown in Figs. 4 and 5, the positive electrode terminal 20 extends from the left end portion (the one end portion) of the exterior body 1 2, and the negative electrode terminal 22 is from the right side of the exterior body 12. The end (the end on the other side) extends out. The positive electrode terminal 20 is electrically connected to the positive electrode of the electric storage unit 18. The negative electrode terminal 22 is electrically connected to the negative electrode of the electric storage unit 18. The material of the positive electrode terminal 20 is, for example, aluminum. The material of the negative terminal 22, for example, copper or nickel. The heat radiating plate 30 is disposed on the outer surface of the outer casing 12 as shown in Fig. 5. In the example shown in Fig. 5, the heat dissipation plate 30 is disposed in contact with the flat outer surface 14b. Not shown in the figure, however, the heat sink 30 may be disposed in contact with the flat outer surface 16b. The heat sink 30 may also be provided to cover the entire flat outer surface 14b or the flat outer surface 16b. Thereby, heat dissipation can be improved. As shown in Fig. 4, the outer casing 12 is disposed, for example, on the inner side of the outer periphery of the heat dissipation plate 30 when viewed from the plane (for example, when viewed from the thickness direction of the heat dissipation plate 30-15-12122). That is, the area of the heat dissipation plate 30 is larger than the area of the exterior body 12 when viewed in plan. Thereby, the surface area of the heat dissipation plate 30 can be increased, and heat dissipation can be improved. Further, the positive electrode terminal 20 and the negative electrode terminal 22 are disposed so as to protrude outward from the outer circumference of the heat dissipation plate 30 when viewed from the plane. Thereby, the connection of the terminals 20 and 22 and the external wiring (not shown) can be facilitated, and the current can be easily obtained from the positive electrode terminal 20. The material of the heat sink 30 is, for example, aluminum, iron, copper, or an alloy containing any of these metals as a main component from the viewpoint of thermal conductivity. Among these metals, aluminum is preferred from the viewpoint of weight reduction. The shape of the heat sink 30 is not particularly limited. However, in the examples shown in Figs. 4 and 5, the shape is flat. Although not shown, the heat sink 30 may have irregularities on its surface. Thereby, the surface area of the heat dissipation plate 30 can be increased, and heat dissipation can be improved. The thickness of the heat dissipation plate 30 is preferably ΙΟμηι or more and 300 μm or less, and more preferably 50 μm or more and 200 μm or less. The heat sink 30 can dissipate heat generated by the electric storage unit 18. Further, the heat radiating plate 30 can uniformly diffuse the heat generated by the electric storage unit 18 to the entire electric storage unit 18, thereby suppressing local temperature rise. For example, when the amount of heat generated in the central portion of the electricity storage unit 18 is larger than the amount of heat generated at the end portion, the heat generation plate 30 can be used to uniformize the heat generation. The method of providing the heat sink 30 to the exterior body 12 is not particularly limited. However, a method of attaching the surface of the heat dissipation plate 30 to the outer surface of the exterior body 12 is used. More specifically, for example, a heat-pressible resin (-16-201212337 ethylene-vinyl acetate copolymer resin, an olefin resin, or the like) or an adhesive (a hot-melt type adhesive, a moisture-curing type adhesive, or a pressure) may be used. A follow-up method of an adhesive for a thermally conductive cartridge of a sensitive adhesive or the like. Further, by mixing an inorganic binder such as boron nitride or an organic binder such as an epoxy resin with an adhesive, the thermal conductivity can be further improved. Therefore, in the present invention, the configuration in which the bonding agent is interposed between the heat dissipation plate 3A and the exterior body 12 is also included in the configuration in which the heat dissipation plate 3 is in contact with the outer surface of the exterior body 12. example. Further, the heat sink 30 and the exterior body 12 may be thermally fused, or may be crimped by a press method. Further, the heat sink 30 may be brought into contact with the exterior body 12 by a suitable jig (not shown). Further, when an adhesive is used, in order to improve heat dissipation, the adhesive may not be present outside the adhesive surface, and only the adhesive may be present on the adhesive surface. Next, the internal structure of the battery 1A will be described. Fig. 6 is a cross-sectional view showing a part of the electric storage device 600 of the present embodiment, and is a schematic cross-sectional view showing the internal structure of the battery 10 (the outer casing 12) shown in Fig. 5.

The positive electrode 1, the negative electrode 2, and the separator 4 have a sheet-like shape. In the example shown in the figure, the electrode laminate 5 is sequentially laminated with the negative electrode 2, the positive electrode 1, the negative electrode 2, the positive electrode 1, and the negative electrode 2 from the flat inner surface 16a of the second outer film 16, and is in the pole and the pole. The separator 4 is interposed between the intermediate and the poles and the outer casing. In the case of the electrode laminate 5, the positive electrode 1 and the -17-201212337 negative electrode 2 are respectively coupled. Further, the number of the positive electrode 1 and the negative electrode 2 is not particularly limited. The form of the electrode laminate 5 is not limited to the illustrated example. For example, the positive electrode, the negative electrode, and the separator may be stacked to form a laminated sheet, and the rolled-back structure may be wound up. The positive electrode 1, as shown in Fig. 6, has a positive electrode current collector la and a living material layer lb.

The positive electrode active material layer 1b is formed on the positive electrode current collector 1a. The positive material layer lb, as shown in Fig. 6, can be formed on the positive electrode current collector: formed on both sides, or formed on only one side. The positive electrode active material layer lb is not particularly limited, and is, for example, 60 μm or more and 90 μm or less. The positive electrode active material layer 1b is adjusted into a slurry by, for example, dispersing a powdery positive electrode active, a conductive auxiliary agent, and a binder in a solvent of an aqueous solvent, and then applying the slurry to the positive electrode current collector. The table is dried to form * When the electricity storage unit 18 is a lithium ion capacitor or an electric double layer capacitor, the positive electrode is reversibly loaded with an anion such as hexafluorophosphate (PF6-) and tetrafluoroboric acid BF4-). More specifically, the positive electrode active material, the activated carbon, and the heat-treated product of the aromatic condensation polymer are polyacene. In addition, the positive electrode of the layer is made of a positive electrode, and the material does not have a positive electrode. a thickness of the material organic surface and a living salt (for example, the compound-18-201212337 quality (PAS). When the electricity storage unit 18 is a lithium ion battery, the positive electrode active material is a substance that reversibly contains lithium ions. More specifically The 'positive electrode active material' is, for example, a lithium nickel based oxide, a lithium cobalt based oxide, a lithium manganese based oxide, an iron phosphate based compound, and a mixture thereof. Further, "lithium nickel based oxide" means lithium.

Above, lithium-cobalt oxides and lithium manganese oxides The conductive auxiliary agent is, for example, a carbon material such as carbon black (acetylene black or the like) or a metal powder such as nickel powder. For the adhesive, for example, methyl cellulose (MC) or carboxymethyl cellulose (CMC) can be used. , cellulose such as ethyl cellulose (EC), polyvinyl alcohol, polyacrylate, polyoxyalkylene (for example, polyethylene oxide), polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE), poly a fluorine-based polymer such as a vinylidene fluoride-hexafluoropropylene copolymer (PVDF-HFP) or an organic polymer such as a styrene butadiene block copolymer (SBR). The negative electrode 2, as shown in Fig. 6, The negative electrode current collector 2a and the negative electrode active 19 _ 201212337 material layer 2b.

The thickness of the active material layer 2b is not particularly limited, and is, for example, 60 μm or more and 90 μm or less. The negative electrode active material layer 2b is, for example, dispersed in a powdery negative electrode active material, a conductive auxiliary agent, and a binder. The slurry is adjusted to a slurry in an aqueous solvent or an organic solvent, and then the slurry is applied onto the surface of the negative electrode current collector and dried to form.

The separator 4 can isolate the positive electrode 1 and the negative electrode 2 from each other. Further, the separator 4 can infiltrate the electrolyte. Further, when the electrolyte of the electricity storage unit 18 is a solid electrolyte, the separator 4 is not used because the separator 4 is not used and the short circuit between the positive electrode 1 and the negative electrode 2 does not occur. The electrolyte, for example, is a nonaqueous electrolyte. The non-aqueous electrolyte may be, for example, a liquid non-aqueous electrolyte containing a non-aqueous organic solvent as a main component, or a gel-like solid electrolyte.

According to the electrical storage device 600 of the present embodiment, the heat radiating plate 30 is in contact with the inner surface 603 of the casing 602. As a result, the heat generated by the power storage device 600 and the battery 10 - 21 - 201212337 is transmitted to the casing 602 via the heat dissipation plate 30, and heat is radiated from the casing 602. Therefore, the power storage device 600 can have high heat dissipation. Further, the power storage device 600 of the present embodiment has high heat dissipation, and is particularly suitable for use in a lithium ion capacitor in which the battery 10 has a high capacity and generates a large amount of heat due to charge and discharge. 2. Modified Example Next, a power storage device according to a modification of the embodiment will be described with reference to the drawings. In the case of the power storage device according to the modification of the present embodiment, the same components as those of the power storage device 600 of the present embodiment will be denoted by the same reference numerals, and detailed description thereof will be omitted. 2. 1. Power storage device according to the first modification. First, an electrical storage device according to a first modification of the present embodiment will be described with reference to the drawings. Fig. 7 is a schematic plan view showing a part of a power storage device 300 according to a first modification of the embodiment. Fig. 8 is a schematic view showing a part of power storage device 300 according to a first modification of the present embodiment, as viewed from a direction VIII of Fig. 7. Further, Fig. 7 corresponds to Fig. 4, and Fig. 8 corresponds to Fig. 5. In the case of the power storage device 600, as shown in Fig. 4, the exterior body 12 is disposed inside the outer periphery of the heat dissipation plate 30, and one of the heat dissipation plates 30 overlaps with one of the terminals 20 and 22. On the other hand, in the power storage device 300, in the plan view shown in FIG. 7, the heat dissipation plate 30 and the terminals 20 and 22 are not overlapped, that is, the heat dissipation plate 30, and the terminals 20 and 22 are isolated from each other in plan view-22 - 201212337 For example, when the temperature of the battery rises due to repeated charge and discharge of the battery, and the temperature inside the battery rises above the heat limit of the material, gas may be generated by decomposition of the electrolyte or the like. Second, the gas causes the internal pressure of the battery to rise, which in turn causes the battery to deform. In addition, the heat sink may be deformed by the deformation of the battery. When the heat sink is deformed and the heat sink is in contact with the terminal, a short circuit may occur between the positive terminal and the negative terminal. However, according to the electric storage device 300, even if the heat radiating plate 30 is deformed, the contact of the heat radiating plate 30 with the terminals 20, 22 can be prevented. 2. 2. Power storage device according to the second modification. Next, a power storage device according to a second modification of the embodiment will be described with reference to the drawings. Fig. 9 is a schematic plan view showing a power storage device 400 according to a second modification of the embodiment. Fig. 10 is a schematic view showing a power storage device 400 according to a second modification of the embodiment, as viewed from the X direction of Fig. 9. Further, Fig. 9 corresponds to Fig. 4, and Fig. 10 corresponds to Fig. 5. In the case of the power storage device 100, as shown in FIGS. 4 and 5, the positive electrode terminal 20 extends from the end of one side of the exterior body 12, and the negative electrode terminal 22 is the other from the exterior body 1 2 . The end of one side extends out. On the other hand, in the power storage device 400, as shown in Fig. 9 and Fig. 1 , the terminals 2A and 22' are extended from the one end portion (for example, the right end portion). Further, the heat sink 30 and the terminals 20 and 22' may not overlap each other in the plan view shown in Fig. 9. Thereby, the contact between the heat dissipation plate 30 and the terminals 20 -23 - 201212337 , 22 can be prevented. 2 . 3. Power storage device according to the third modification. Next, a power storage device according to a third modification of the present embodiment will be described with reference to the drawings. Fig. 1 is a schematic view showing a power storage device 700 according to a third modification of the embodiment, corresponding to Fig. 2 . Fig. 12 is a schematic view showing a power storage device 700 according to a third modification of the embodiment, as viewed from the XII direction of Fig. 1 . In the power storage device 700, as shown in Fig. 1, the heat radiating plate 30 is in contact with the inner surface 603 (e.g., the upper surface or the lower surface) of the frame 602 which is identical to each other. That is, through the battery 10, one of the adjacent heat sinks 30 contacts the first inner surface 603a (for example, the upper surface) of the frame 602, and the other heat sink 30 contacts the heat sink 30. The second inner surface 603b (for example, the lower surface) different from the first inner surface 603a of the casing 602. In the example shown in Fig. 1, the heat dissipation plate 30 sandwiched between the battery 10a and the battery 10b, and the heat dissipation plate 30 sandwiched between the battery 10c and the battery 10d are in contact with the first inner surface 603a. The heat dissipation plate 30 sandwiched between the battery 1 Ob and the battery 10 0 and the heat dissipation plate 30 at both ends are in contact with the second inner surface 603b. Thereby, heat is not concentrated on one part of the frame 012, and heat is dispersed throughout, so that heat can be efficiently dissipated. Further, the heat sink 30, as shown in Fig. 12, may also contact the inner surface (side surface) of the frame 602. That is, the heat dissipation plate 30 may also be in contact with the three inner faces 603 of the frame 602. Thereby, the heat can be uniformly conducted to the frame 602. Further, although not shown, the heat sink 3' can be connected to a cooling mechanism such as a unit of -24-201212337. With this form, the heat dissipation of the power storage device 70 can also be improved. 4. Power storage device according to the fourth modification. Next, a power storage device according to a fourth modification of the embodiment will be described with reference to the drawings. Fig. 13 is a schematic view of a power storage device 800 according to a fourth modification of the embodiment, corresponding to Fig. 2. Fig. 14 is a view showing a state in which the power storage device 8A according to the fourth modification of the present embodiment is viewed from the XIV direction of Fig. 13. In the case of the power storage device 600, as shown in Fig. 2, the battery 10a, the battery 10b, the battery 10c, and the battery 10d are disposed in this order, and the heat dissipation plates 3 are disposed so as to sandwich the batteries. In the case of the power storage device 8 ,, as shown in Fig. 13, the heat dissipation plate 30' is disposed only between the battery 10a and the battery 100b, and between the battery 100c and the battery 10d. In the case of the power storage device 800, the battery 10b and the battery 10c are disposed apart from each other by a gap. According to the example of the power storage device 800', for example, compared with the case of the power storage device 600, when the gas is generated in the battery 10, the battery 1 is easily deformed (expanded) because of the gap between the batteries 1〇. Therefore, the power storage device 800' can have high reliability. When gas is generated in the battery and the battery is not deformed, there is a possibility that the internal pressure of the battery rises sharply and malfunctions. 2. 5. Power storage device according to the fifth modification - 25 - 201212337 Next, the power storage device according to the fifth modification of the embodiment will be described with reference to the drawings. Fig. 15 is a schematic view of a power storage device 900 according to a fifth modification of the embodiment, corresponding to Fig. 2. Fig. 16 is a schematic view showing a power storage device 900 according to a fifth modification of the embodiment, as viewed from the XVI direction of Fig. 15. Fig. 17 is a schematic view showing a part of a power storage device 900 according to a fifth modification of the embodiment. Fig. 18 is a schematic perspective view showing a part of power storage device 900 according to an eighth modification of the present embodiment. In addition, in FIG. 17, for convenience, only one battery 10, the terminals 20 and 22 disposed in the battery 10, the heat dissipation plate 30 disposed in the battery 10, and the battery 10 are disposed. The fixing member 40. Further, in Fig. 18, only one battery 10, terminals 20 and 22 disposed in the battery 10, and fixing members 40 disposed in the battery 10 are illustrated for convenience. The power storage device 9 00 has a fixed member 40 as shown in Figs. 15 to 18 . The fixing member 40 is disposed on the outer surface of the exterior body 12, for example, avoiding the heat dissipation plate 30. That is, the fixing member 40 and the heat dissipation plate 30 do not overlap. In the example shown in Fig. 17, the heat radiating plate 30 is disposed at the central portion of the flat outer faces 14b and 16b. The fixing member 40 is disposed so as to avoid the central portion of the flat outer surface 14b so as to be inclined from the flat outer surface 14b to the inclined outer surface 14c which is continuous with the flat outer surface 14b. The fixing member 40 is disposed so as to avoid the central portion of the flat outer surface 16b, and is configured such that the flat outer surface 16b is inclined to the outer surface 16c with respect to the flat outer surface 16b continuous with the flat outer surface 16b. In the example shown in the figure, the fixed member 40 is provided with four batteries. For example, as shown in Fig. 17, the fixing member -26-201212337 40 (the first fixing member 40a) on the first outer film 14 side and the fixing member 40 on the second outer film 16 side (the The fixing member 40 b) holds the battery 10 and fixes the battery 10 in the casing 602. More specifically, the first fixing member 40a is disposed from the flat outer surface 14b of the first exterior film 14 to the inclined outer surface 14c. The second fixing member 40b is disposed from the flat outer surface 16b of the second exterior film 16 to the inclined outer surface 16c. The fixing member 40 has a projection 42 as shown in Fig. 18. In the protruding portion 42, a portion (flat outer surfaces 14b, 16b, etc.) that protrudes due to the housing 12 (battery 10) other than the electric storage unit 18 can be accommodated. Thereby, the battery 10 can be stably fixed. For the method of disposing the fixing member 40 and the exterior body 12, for example, a heat-pressable resin (such as an ethylene-vinyl acetate copolymer resin or an olefin resin) and an adhesive (a hot-melt type adhesive or a moisture-curing type) can be used. The adhesive agent, pressure sensitive adhesive, or the like) is used as a bonding agent having high thermal conductivity. Further, an inorganic binder such as boron nitride or an organic binder such as an epoxy resin may be mixed to the adhesive. The fixing member 40 can be coupled to the inner surface 603 of the casing 021 to fix the battery 10 in the casing 602. The material of the fixing member 40 is, for example, aluminum, iron, copper, or an alloy containing any one of the metals. The method of connecting the fixing member 40 and the frame 602 is not particularly limited. However, for example, it can be screwed to the screw hole 44 of the fixing member 40 (refer to FIG. 18) to fix it in the frame 602. The surface 603 may be fixed by welding or may be implemented by an adhesive as exemplified by the fixing member 40 and the mounting method of the exterior body 12. The rigidity of the fixing member 40 may also be greater than the rigidity of the heat dissipation plate 30. With this -27-201212337, the battery 10 can be stably fixed. For example, as shown in Fig. 19, the rigidity of the fixing member 40 is made larger than the rigidity of the heat radiating plate 30 by making the thickness of the fixing member 40 larger than the thickness of the heat radiating plate 30. Further, in the example shown in Fig. 15, the adjacent batteries 10 share one heat radiating plate 30. However, in the example shown in Fig. 19, one battery 10 is provided with two heat radiating plates 30. In addition, in the example shown in Fig. 15 and Fig. 19, four batteries 1 are provided. However, the number is not particularly limited. For example, one battery 10 may be provided, or four or more batteries may be provided. The battery 10 can be appropriately set according to its intended output voltage and output current. According to the electrical storage device 900, the battery 10 can be stably fixed in the casing 602 by the fixing member 40. Therefore, the power storage device 900 can have high reliability. Further, in the power storage device 900, the rigidity of the fixing member 40 can be made larger than the rigidity of the heat dissipation plate 30 by making the thickness of the fixing member 40 larger than the thickness of the heat dissipation plate 30. Thereby, even in the battery 10, when the battery 10 is deformed by the generation of the gas, the fixing member 40 having a large rigidity can maintain the stability of the battery 10, and the heat sink 30 can follow the battery 1 because of the low rigidity. 0 deformation. For example, a rigid plate with a large rigidity cannot follow the deformation of the battery, and sometimes the contact between the battery and the heat sink is insufficient. It even causes the heat sink to peel off from the battery. Therefore, it sometimes causes a decrease in heat dissipation. According to the power storage device 900, such a problem can be eliminated, and the stability and fixation of the battery 10 can be maintained, so that heat dissipation can be achieved. Further, in the examples shown in Figs. 15 and 17, since the fixing member 40 and the heat radiating plate 30 are not overlapped, the fixing member 40 does not interfere with the deformation of the heat radiating plate 30, and the heat radiating plate 30 can be followed by -28-201212337. The deformation of the battery 〇. Further, in the present invention, "rigidity" refers to the degree to which an object resists deformation when an external force is applied to an object to deform. That is, the smaller the rigidity, the more easily the object is deformed (easy to bend). Further, as shown in FIG. 20, the power storage device 900 may have a heat dissipation plate 30 between the fixing member 40 and the battery 1A. That is, a portion of the fixing member 40 and a portion of the heat dissipation plate 30 may also overlap. Thereby, it is possible to more reliably suppress the peeling of the heat radiating plate from the battery. 2. 6. Power storage device according to a sixth modification. Next, a power storage device according to a sixth modification of the present embodiment will be described with reference to the drawings. Fig. 2 is a schematic view showing a power storage device 1A according to a sixth modification of the present embodiment, and corresponds to the fifth embodiment, and mainly relates to the power storage device 10 00 according to the sixth modification of the embodiment. The difference from the power storage device 900 according to the fifth modification of the embodiment will be described. In the case of the power storage device 900, as shown in Fig. 15, four fixing members 40 are disposed for one battery 10. On the other hand, in the case of the power storage device 1 as shown in FIG. 2, two fixing members 40 are disposed for one battery 10. More specifically, two storage batteries 1 ’ ′ are disposed with the heat dissipation plate 30 interposed therebetween, and two fixing members 40 are disposed with the battery 10 interposed therebetween. According to the power storage device 1A, for example, when the gas is generated in the battery 10 as compared with the case of the power storage device 900, the battery 10 is easily deformed (expanded). Even if gas is generated in the battery and the battery cannot be deformed, the internal pressure of the battery will increase significantly, and malfunction may occur. -29 201212337 The present invention is not limited to the above embodiment, and various modifications can be made.
