本発明の実施形態を、図面を参照しつつ説明する。   Embodiments of the present invention will be described with reference to the drawings.

1 is a perspective view showing the battery module according to the first embodiment, FIG. 2 is an exploded perspective view of the battery module, FIG. 3 is a partial sectional view showing a thin battery (unit cell) forming the battery module, and FIG. FIG. 4 is a partial cross-sectional view showing a structure for fixing a metal lid to an insulating case of the battery module, where (A) shows before fixing and (B) shows after fixing.

第１実施形態に係る電池モジュール１は、絶縁材料からなる絶縁ケース２と、絶縁ケース２に収納される積層された複数の薄型電池３（すなわち、複数の薄型電池３を積層して形成された電池積層体であり、以下ではセルユニット１２と称する）と、セルユニット１２を積層方向から挟む２枚の金属製の金属蓋４と、を有している。絶縁ケース２および金属蓋４は、セルユニット１２を収納するモジュールケースとしての機能を果している。   The battery module 1 according to the first embodiment is formed by stacking an insulating case 2 made of an insulating material and a plurality of thin batteries 3 stacked in the insulating case 2 (that is, a plurality of thin batteries 3). A battery stack, hereinafter referred to as a cell unit 12), and two metal metal lids 4 sandwiching the cell unit 12 from the stacking direction. The insulating case 2 and the metal lid 4 function as a module case that houses the cell unit 12.

薄型電池３は、図３に示すように、金属箔層５の両面に表面樹脂層６および溶着樹脂層７を積層したシート状部材で形成された電池外装材８により発電要素９を覆って形成される二次電池であり、発電要素９に接続された電極端子１０が電池外装材８内部から外部に導出されている。積層される薄型電池３のそれぞれは、電極端子１０が直列または並列に電気的に接続されてセルユニット１２を形成し、このセルユニット１２に接続された正負極一組のモジュール出力端子１１が設けられる。なお、このモジュール出力端子１１は、セルユニット１２としての出力端子であり、従って、複数の薄型電池３が並列接続されたセルユニットであれば、全ての薄型電池３の正負極端子に接続され、複数の薄型電池３が直列に接続されたセルユニットであれば、最上電位の薄型電池３の正極電極端子と、最下位の薄型電池３の負極電極端子に接続される。   As shown in FIG. 3, the thin battery 3 is formed by covering the power generating element 9 with a battery exterior member 8 formed of a sheet-like member in which a surface resin layer 6 and a welding resin layer 7 are laminated on both surfaces of a metal foil layer 5. The electrode terminal 10 connected to the power generation element 9 is led out from the inside of the battery exterior material 8 to the outside. Each of the laminated thin batteries 3 has a cell unit 12 in which electrode terminals 10 are electrically connected in series or in parallel, and a set of module output terminals 11 connected to the cell unit 12 are provided. It is done. In addition, this module output terminal 11 is an output terminal as the cell unit 12. Therefore, if the cell unit is a plurality of thin batteries 3 connected in parallel, the module output terminal 11 is connected to the positive and negative terminals of all the thin batteries 3. In the case of a cell unit in which a plurality of thin batteries 3 are connected in series, the positive electrode terminal of the thin battery 3 having the highest potential and the negative electrode terminal of the thin battery 3 having the lowest potential are connected.

電池外装材８の金属箔層５は、例えばアルミニウムからなり、表面樹脂層６は、例えばナイロンからなり、溶着樹脂層７は、例えばポリプロピレンからなるが、電気絶縁性と電解液に対する耐性を満足する材料であれば他の材質でもよい。   The metal foil layer 5 of the battery outer packaging material 8 is made of, for example, aluminum, the surface resin layer 6 is made of, for example, nylon, and the welding resin layer 7 is made of, for example, polypropylene, but satisfies the electrical insulation and the resistance to the electrolytic solution. Other materials may be used as long as they are materials.

絶縁ケース２は絶縁性の樹脂製であり、重ねられた複数の薄型電池３（セルユニット１２）の側面を覆うとともに、セルユニット１２の薄型電池３積層方向の両面が開口している。絶縁ケース２の両開口部側の面の四隅には、絶縁ケース２と一体で形成されるピン部１３が形成されている。また、絶縁ケース２には、モジュール出力端子１１が嵌合する形状の端子嵌合部１４と、電池モジュール１の電圧測定用のコネクタが外部と接続するためのコネクタ導出穴１５とが、側面に形成される。   The insulating case 2 is made of insulative resin, covers the side surfaces of the stacked thin batteries 3 (cell units 12), and opens both surfaces of the cell units 12 in the stacking direction of the thin batteries 3. Pin portions 13 formed integrally with the insulating case 2 are formed at the four corners of the surface on the both opening side of the insulating case 2. Further, the insulating case 2 has a terminal fitting portion 14 shaped to fit the module output terminal 11 and a connector lead-out hole 15 for connecting a voltage measurement connector of the battery module 1 to the outside. It is formed.

金属蓋４は、表面に電気的に絶縁性の樹脂が被覆されて絶縁処理されていることが好ましく、本実施携帯では、アルミニウム製の板にPET樹脂フィルムが被覆されている。なお、金属蓋４の材質および被覆する樹脂の材質として、他の材質を使用することも可能である。   The metal lid 4 is preferably coated with an electrically insulating resin on the surface and insulated, and in this embodiment, a plate made of aluminum is coated with a PET resin film. It should be noted that other materials can be used as the material of the metal lid 4 and the resin material to be coated.

金属蓋４の四隅には、絶縁ケース２のピン部１３に対応して、貫通孔１６が設けられる。   In the four corners of the metal lid 4, through holes 16 are provided corresponding to the pin portions 13 of the insulating case 2.

金属蓋４は、絶縁ケース２に収納された薄型電池３の積層方向の両面から薄型電池３を挟み、絶縁ケース２のピン部１３が貫通孔１６に挿通され、図４に示すようにピン部１３を潰すことによって絶縁ケース２と固定される。このように、貫通孔１６とピン部１３により構成される固定手段により、金属蓋４がセルユニット１２を積層方向から所定の圧力で押圧しつつ、挟持する。この際には、例えば絶縁ケース２の開口方向の厚さを、積層された薄型電池３よりも多少短くすることにより、金属蓋４によりセルユニット１２に圧力を付与することができる。このように薄型電池３に所定の圧力を付与することにより、電池の寿命を確保することができる。ピン部１３および貫通孔１６の位置や数は、任意に変更することが可能である。また、ピン部１３を潰すのではなく、ピン部１３に反しをつけて固定することもできる。また、ネジやボルトを用いて固定したり、接着剤を用いることも可能である。   The metal lid 4 sandwiches the thin battery 3 from both sides in the stacking direction of the thin battery 3 housed in the insulating case 2, and the pin portion 13 of the insulating case 2 is inserted into the through hole 16, as shown in FIG. 4. The insulating case 2 is fixed by crushing 13. In this way, the metal lid 4 holds the cell unit 12 while pressing the cell unit 12 with a predetermined pressure from the stacking direction by the fixing means constituted by the through hole 16 and the pin portion 13. At this time, for example, by making the thickness of the insulating case 2 in the opening direction slightly shorter than that of the stacked thin batteries 3, the metal unit 4 can apply pressure to the cell unit 12. Thus, by applying a predetermined pressure to the thin battery 3, it is possible to ensure the life of the battery. The positions and number of the pin portions 13 and the through holes 16 can be arbitrarily changed. Further, instead of crushing the pin portion 13, the pin portion 13 can be warped and fixed. It is also possible to fix with screws or bolts or to use an adhesive.

薄型電池３から導出されるモジュール出力端子１１は、絶縁ケース２の端子嵌合部１４（モジュールケース内部から外部に貫通した端子嵌合部、すなわち貫通孔）に嵌合される。ケースが金属製の場合には、モジュール出力端子１１とケースの間を絶縁するための部材が必要となるが、本実施形態では絶縁材からなる絶縁ケース２が用いられるため、他の絶縁部材を設けることなしにモジュール出力端子１１を絶縁ケース２に直接固定できる。   The module output terminal 11 derived from the thin battery 3 is fitted into a terminal fitting portion 14 (a terminal fitting portion that penetrates from the inside of the module case to the outside, that is, a through hole) of the insulating case 2. When the case is made of metal, a member for insulating between the module output terminal 11 and the case is required. However, in this embodiment, since the insulating case 2 made of an insulating material is used, other insulating members are used. The module output terminal 11 can be directly fixed to the insulating case 2 without being provided.

本実施形態により、薄型電池３の電極端子１０や、薄型電池３の電池外装材８に使用される金属箔層５の端部が触れる可能性のある絶縁ケース２が絶縁材からなるため、薄型電池３の絶縁を確実に確保できる。   According to the present embodiment, since the insulating case 2 that may be touched by the electrode terminal 10 of the thin battery 3 and the end of the metal foil layer 5 used for the battery exterior material 8 of the thin battery 3 is made of an insulating material, the thin case is thin. The insulation of the battery 3 can be ensured reliably.

また、セルユニット１２の薄型電池３積層方向表面に金属蓋４が接するため、電池モジュール１の冷却能力を確保することができる。   Moreover, since the metal lid 4 is in contact with the surface of the cell unit 12 in the stacking direction of the thin battery 3, the cooling capacity of the battery module 1 can be ensured.

また、金属蓋４に絞り加工を施す必要が必ずしもないため、金属蓋４に被覆される樹脂が損傷し難く、絶縁を確保し易い。   In addition, since it is not always necessary to perform drawing processing on the metal lid 4, the resin coated on the metal lid 4 is not easily damaged and it is easy to ensure insulation.

図５は第１実施形態に係る電池モジュール１の変形例を示す斜視図である。   FIG. 5 is a perspective view showing a modification of the battery module 1 according to the first embodiment.

第１実施形態に係る電池モジュール１の変形例として、絶縁ケース２の側面に、冷却空気が流入出可能な通気孔１７を形成することができる。なお、通気孔１７は、絶縁ケース２を成形型を用いて成形する際に、スライド型を用いることによって容易に形成することが可能である。   As a modification of the battery module 1 according to the first embodiment, a vent hole 17 through which cooling air can flow in and out can be formed on the side surface of the insulating case 2. The vent hole 17 can be easily formed by using a slide mold when the insulating case 2 is molded using a mold.

＜第２実施形態＞

FIG. 6 is an exploded perspective view showing the battery module according to the second embodiment. In addition, about the site | part which has the same function as 1st Embodiment, the same code | symbol is used and in order to avoid duplication, the description is abbreviate | omitted.

第２実施形態に係る電池モジュール２０の絶縁ケース２１は、薄型電池３の積層方向の一方面のみが開口している。したがって、金属蓋４も開口部が設けられる一方面にのみ設けられる。例えば、絶縁ケース２１の開口部の深さが、積層された薄型電池３よりも多少短く設定されることにより、金属蓋４によって薄型電池３に圧力を付与することができる。   In the insulating case 21 of the battery module 20 according to the second embodiment, only one surface of the thin battery 3 in the stacking direction is opened. Therefore, the metal lid 4 is also provided only on one surface where the opening is provided. For example, by setting the depth of the opening of the insulating case 21 to be slightly shorter than the stacked thin batteries 3, the metal lid 4 can apply pressure to the thin batteries 3.

第２実施形態に係る電池モジュール２０は、第１実施形態よりも冷却能力が劣るが、第１実施形態よりも絶縁能力に優れ、また絶縁ケース内において薄型電池３を位置決めし易く、製造が容易であるという利点がある。   The battery module 20 according to the second embodiment is inferior in cooling capacity to the first embodiment, but has better insulation performance than the first embodiment, and the thin battery 3 is easily positioned in the insulation case, and is easy to manufacture. There is an advantage of being.

＜第３実施形態＞

The module output terminal 32 can be easily installed by inserting into the mold and insert molding when molding the insulating case 31.

また、積層される薄型電池３からは、第１実施形態におけるモジュール出力端子１１の代わりに、電極端子１０が直列または並列に電気的に接続されて、一組のモジュール出力タブ３３が設けられる。このモジュール出力タブ３３は、電池モジュール３０が組み立てられる際に、絶縁ケース３１のモジュール出力端子３２に対してレーザ溶接またはスポット溶接により接続される。   Moreover, from the laminated thin battery 3, instead of the module output terminal 11 in the first embodiment, the electrode terminals 10 are electrically connected in series or in parallel, and a set of module output tabs 33 is provided. The module output tab 33 is connected to the module output terminal 32 of the insulating case 31 by laser welding or spot welding when the battery module 30 is assembled.

なお、本発明は上述した実施の形態に限定されるものではなく、特許請求の範囲の範囲内で種々改変することができる。例えば、第２，第３実施形態の絶縁ケース２１，３１に通気孔１７を設けてもよく、また第３実施形態の絶縁ケース３１の開口を、第２実施形態のように一方面にのみ設けてもよい。また、薄型電池３は、必ずしも矩形でなくてもよい。   The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the claims.
