Description

本発明は、蓄電素子がラミネートフィルムに収納されたラミネート電池セル、及びラミネート電池セルが複数積層されたラミネート電池モジュールに関する。   The present invention relates to a laminate battery cell in which a storage element is housed in a laminate film, and a laminate battery module in which a plurality of laminate battery cells are laminated.

従来より電動車両などには電池モジュールが搭載されている。電動車両などに用いられる比較的容量の大きな電池モジュールを構成する電池は、充放電可能な二次電池で構成されており、充放電過程で電池の内部抵抗による発熱で電池の温度が上昇する。特に、放電時には電池の内部からの発熱反応熱まで加えられるので、発熱の程度がさらに大きく、それによる温度上昇はさらに大きくなる。電池の温度が上昇すると、電池の寿命特性が低下する虞があり、電池を冷却することが重要となっている。   Conventionally, a battery module is mounted on an electric vehicle or the like. A battery constituting a battery module having a relatively large capacity, which is used for an electric vehicle or the like, is constituted of a chargeable / dischargeable secondary battery, and the temperature of the battery rises due to heat generation due to the internal resistance of the battery in the charge / discharge process. In particular, since the exothermic reaction heat from the inside of the battery is added at the time of discharge, the degree of heat generation is further increased, and the temperature rise thereby is further increased. When the temperature of the battery rises, the life characteristics of the battery may be degraded, and it is important to cool the battery.

例えば特許文献１には、ラミネートシートからなる電池ケースに収容された２つ以上の電池組立体の間に放熱部材を介在させ、放熱部材の一部を外部に露出させることで、充放電時に電池セルの内部で発生する熱を放熱部材を介して外部に伝達させることが記載されている。   For example, according to Patent Document 1, a battery with heat dissipation is interposed between two or more battery assemblies housed in a battery case made of a laminate sheet, and a part of the heat dissipation member is exposed to the outside, thereby allowing battery to be charged or discharged. It is described that the heat generated inside the cell is transmitted to the outside through the heat dissipation member.

特表２０１５−５２２９１２号公報JP-A-2015-522912

しかしながら、特許文献１に記載の冷却機構では、放熱部材を介してのみ放熱するもので、放熱性能の点で改善の余地があった。   However, in the cooling mechanism described in Patent Document 1, heat is dissipated only through the heat dissipation member, and there is room for improvement in terms of heat dissipation performance.

本発明は、ラミネート電池セル及びラミネート電池モジュールにおいて、放熱性能を向上させる技術を提供する。   The present invention provides a technology for improving the heat dissipation performance in a laminate battery cell and a laminate battery module.

先ず、本発明の第１実施形態に係るラミネート電池セルについて図１〜図５を参照しながら説明する。 First Embodiment
First, a laminated battery cell according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 5.

図１の符号１０は蓄電素子であり、符号１１はセパレータである。セパレータ１１には電解液とリチウムイオンが含浸されている。セパレータ１１の片面には、正極１２が形成されている。正極１２は、例えば、ＬｉＭＯ２（Ｍは金属元素）などの正極活物質とアセチレンブラックなどの正極導電材とをＰＶＤＦなどのバインダーで固めて構成される。セパレータ１１の他面には、負極１３が形成されている。負極１３は、Ｓｉなどの負極活物質とアセチレンブラックなどの負極導電材とをＰＶＤＦなどのバインダーで固めて構成される。図１において符号１４は正極集電箔であり、符号１５は負極集電箔であり、正極集電箔１４と負極集電箔１５とを区別するため、正極集電箔１４を実線で、負極集電箔１５を点線で示している。 The code | symbol 10 of FIG. 1 is an electrical storage element, and the code | symbol 11 is a separator. The separator 11 is impregnated with an electrolytic solution and lithium ions. The positive electrode 12 is formed on one side of the separator 11. The positive electrode 12 is configured by, for example, solidifying a positive electrode active material such as LiMO 2 (M is a metal element) and a positive electrode conductive material such as acetylene black with a binder such as PVDF. The negative electrode 13 is formed on the other surface of the separator 11. The negative electrode 13 is configured by solidifying a negative electrode active material such as Si and a negative electrode conductive material such as acetylene black with a binder such as PVDF. In FIG. 1, reference numeral 14 denotes a positive electrode current collector foil, and reference numeral 15 denotes a negative electrode current collector foil. In order to distinguish between the positive electrode current collector foil 14 and the negative electrode current collector foil 15, the positive electrode current collector foil 14 is indicated by a solid line The current collector foil 15 is shown by a dotted line.

図２に示すように、上記構成の蓄電素子１０はその厚さ方向に互いに積層され、正極集電箔１４は箔２２で正極集電タブ２３に接続され、負極集電箔１５は箔２４で負極集電タブ２５に接続されている。正極集電タブ２３は、例えばＡｌ板、又はＡｌ板の表面に有機被膜又は無機被膜を設けた金属板と、ポリオレフィン系樹脂からなるタブフィルムと、から構成される。負極集電タブ２５は、例えばＣｕ板、又はＮｉメッキＣｕ板の表面に有機被膜又は無機被膜を設けた金属板と、ポリオレフィン系樹脂からなるタブフィルムと、から構成される。なお、図２以降の図面において、箔２２及び正極集電タブ２３を実線で、箔２４及び負極集電タブ２５を点線で示している。   As shown in FIG. 2, the storage elements 10 of the above configuration are stacked on one another in the thickness direction, the positive current collector foil 14 is connected to the positive current collector tab 23 by a foil 22, and the negative current collector foil 15 is a foil 24. It is connected to the negative electrode current collection tab 25. The positive electrode current collection tab 23 is made of, for example, an Al plate or a metal plate provided with an organic film or an inorganic film on the surface of the Al plate, and a tab film made of a polyolefin resin. The negative electrode current collection tab 25 is composed of, for example, a Cu plate or a metal plate provided with an organic film or an inorganic film on the surface of a Ni-plated Cu plate and a tab film made of a polyolefin resin. In the drawings after FIG. 2, the foil 22 and the positive electrode current collecting tab 23 are indicated by solid lines, and the foil 24 and the negative electrode current collecting tab 25 are indicated by dotted lines.

積層された蓄電素子１０はラミネートフィルム２１で気密に包装されることでラミネート電池セル２０が構成されている。ラミネート電池セル２０は、図３に示すように、蓄電素子１０の積層方向から見て略矩形形状を有し、ラミネート電池セル２０のラミネートフィルム２１の長手方向一方側からは正極集電タブ２３が突出し、ラミネートフィルム２１の長手方向他方側からは負極集電タブ２５が突出している。   The laminated battery cell 10 is airtightly packaged with the laminate film 21 to constitute a laminate battery cell 20. As shown in FIG. 3, the laminated battery cell 20 has a substantially rectangular shape as viewed from the stacking direction of the storage element 10, and the positive electrode current collection tab 23 is from one side in the longitudinal direction of the laminated film 21 of the laminated battery cell 20. The negative electrode current collection tab 25 protrudes from the other side of the laminate film 21 in the longitudinal direction.

ラミネート電池セル２０には、蓄電素子１０が発生する熱を放熱する放熱機構３０が設けられている。放熱機構３０は、ラミネートフィルム２１の一面２１ａ側に配置される冷却部材３１と、負極集電タブ２５又は正極集電タブ２３に接続されるとともに冷却部材３１に接続される放熱部材３５と、を備える。   The laminated battery cell 20 is provided with a heat release mechanism 30 for releasing the heat generated by the storage element 10. The heat dissipation mechanism 30 includes a cooling member 31 disposed on one surface 21 a side of the laminate film 21, and a heat dissipation member 35 connected to the negative electrode current collecting tab 25 or the positive electrode current collecting tab 23 and connected to the cooling member 31. Prepare.

図２及び図３を用いてより具体的に説明すると、ラミネートフィルム２１の一面２１ａには、放熱部材３５を挟んで冷却部材３１が配置されている。放熱部材３５は、一端部が負極集電タブ２５に溶接されるとともに、他端部がラミネートフィルム２１の一面２１ａと冷却部材３１との間に介在する放熱シート又は放熱プレートである。放熱部材３５を放熱シート又は放熱プレートとすることで、ラミネート電池セル２０の大型化を抑制しながら効果的にラミネート電池セル２０の放熱を行うことができる。放熱部材３５は、正極１２及び負極１３の面積と同等の大きさを有する放熱部材本体３５ａと、放熱部材本体３５ａから負極集電タブ２５に延びる放熱部材接合部３５ｂと、を有する。発熱するのは電極であるため、放熱部材本体３５ａを発熱部位と同等の大きさとすることで、冷却効率をあげつつ放熱部材３５を小型化できる。   If it demonstrates more concretely using FIG.2 and FIG.3, the cooling member 31 will be arrange | positioned on one surface 21a of the laminate film 21 on both sides of the thermal radiation member 35. As shown in FIG. The heat dissipating member 35 is a heat dissipating sheet or a heat dissipating plate in which one end is welded to the negative electrode current collecting tab 25 and the other end is interposed between the one surface 21 a of the laminate film 21 and the cooling member 31. By using the heat dissipating member 35 as a heat dissipating sheet or a heat dissipating plate, it is possible to effectively dissipate the heat of the laminate battery cell 20 while suppressing an increase in size of the laminate battery cell 20. The heat dissipating member 35 has a heat dissipating member main body 35 a having a size equal to the area of the positive electrode 12 and the negative electrode 13, and a heat dissipating member bonding portion 35 b extending from the heat dissipating member main body 35 a to the negative electrode current collecting tab 25. Since it is the electrode that generates heat, by making the heat dissipating member main body 35a the same size as the heat generating portion, the heat dissipating member 35 can be miniaturized while improving the cooling efficiency.

なお、図２及び図３の実施形態は、放熱部材３５の一端部が負極集電タブ２５に溶接されたものだが、放熱部材３５の一端部が、負極集電タブ２５の代わりに正極集電タブ２３に溶接されていてもよい。また、放熱部材３５は、金属箔又は金属プレートであることが好ましく、溶接される集電タブと同じ材質であることがさらに好ましい。即ち、放熱部材３５が負極集電タブ２５に溶接される場合、Ａｌ箔又はＡｌ板が好ましく、放熱部材３５が正極集電タブ２３に溶接される場合、Ｃｕ箔又はＣｕ板が好ましい。これにより、放熱部材３５と集電タブ２３、２５の溶接が容易となる。   In the embodiment of FIGS. 2 and 3, one end of the heat dissipation member 35 is welded to the negative electrode current collection tab 25, but one end of the heat dissipation member 35 is positive electrode current collection instead of the negative electrode current collection tab 25. It may be welded to the tab 23. Further, the heat dissipation member 35 is preferably a metal foil or a metal plate, and more preferably the same material as the current collection tab to be welded. That is, when the heat radiating member 35 is welded to the negative electrode current collecting tab 25, an Al foil or an Al plate is preferable, and when the heat radiating member 35 is welded to the positive electrode current collecting tab 23, a Cu foil or a Cu plate is preferable. Thereby, welding of the heat radiating member 35 and the current collection tabs 23 and 25 becomes easy.

冷却部材３１は、例えば、ラミネートフィルム２１の片面に沿って配置される冷却プレートであって、冷却部材３１には、図４に示すように、ラミネート電池セル２０の長手方向に沿って少なくとも１つ冷媒流路３３が内部に形成されていてもよい。図４に記載の冷却部材３１は、２つの冷媒流路３３が内部に形成されたものである。   The cooling member 31 is, for example, a cooling plate disposed along one side of the laminate film 21, and as shown in FIG. 4, at least one cooling member 31 is provided along the longitudinal direction of the laminated battery cell 20. The refrigerant flow path 33 may be formed inside. The cooling member 31 shown in FIG. 4 has two refrigerant channels 33 formed therein.

また、冷却部材３１には必ずしも冷媒流路３３が形成されている必要はなく、図５に示すように、冷媒流路３３が形成された冷媒基板３４から冷却部材３１が立設されていてもよい。なお、冷媒流路３３を流れる冷媒は、液体でもよく、気体でもよい。   Further, the coolant passage 33 is not necessarily formed in the cooling member 31, and as shown in FIG. 5, even if the cooling member 31 is erected from the refrigerant substrate 34 in which the coolant passage 33 is formed. Good. The refrigerant flowing through the refrigerant channel 33 may be liquid or gas.

図２に戻って、このように構成されたラミネート電池セル２０において、蓄電素子１０が発生する熱は、ラミネートフィルム２１の一面２１ａから放熱部材３５を介して冷却部材３１に伝達される放熱経路Ｐ１と、負極集電タブ２５から放熱部材３５を介して冷却部材３１に伝達される放熱経路Ｐ２の２つの放熱経路で冷却部材３１に伝達されるので、効果的にラミネート電池セル２０の放熱を行うことができる。   Returning to FIG. 2, in the laminated battery cell 20 configured as described above, the heat radiation path P1 in which the heat generated by the storage element 10 is transmitted from the one surface 21 a of the laminate film 21 to the cooling member 31 via the heat radiation member 35. Since the heat is transmitted to the cooling member 31 through the two heat radiation paths of the heat radiation path P2 which is transmitted to the cooling member 31 from the negative electrode current collection tab 25 through the heat radiation member 35, the laminate battery cell 20 is effectively dissipated. be able to.

［第２実施形態］

図６を用いてより具体的に説明すると、ラミネートフィルム２１の一面２１ａには、第１放熱部材３５Ａを挟んで第１冷却部材３１Ａが配置される。第１放熱部材３５Ａは、一端部が負極集電タブ２５に溶接されるとともに、他端部がラミネートフィルム２１の一面２１ａと第１冷却部材３１Ａとの間に介在する放熱シート又は放熱プレートである。ラミネートフィルム２１の他面２１ｂには、第２放熱部材３５Ｂを挟んで第２冷却部材３１Ｂが配置される。第２放熱部材３５Ｂは、一端部が正極集電タブ２３に溶接されるとともに、他端部がラミネートフィルム２１の他面２１ｂと第２冷却部材３１Ｂとの間に介在する放熱シート又は放熱プレートである。   If it demonstrates more concretely using FIG. 6, the 1st cooling member 31A will be arrange | positioned on the one surface 21a of the laminate film 21 on both sides of the 1st thermal radiation member 35A. The first heat radiating member 35A is a heat radiating sheet or a heat radiating plate whose one end is welded to the negative electrode current collecting tab 25 and the other end is interposed between the one surface 21a of the laminate film 21 and the first cooling member 31A. . The second cooling member 31B is disposed on the other surface 21b of the laminate film 21 with the second heat radiation member 35B interposed therebetween. The second heat dissipating member 35B is a heat dissipating sheet or a heat dissipating plate whose one end is welded to the positive electrode current collecting tab 23 and the other end is interposed between the other surface 21b of the laminate film 21 and the second cooling member 31B. is there.

このように構成されたラミネート電池セル２０では、蓄電素子１０が発生する熱は、ラミネートフィルム２１の一面２１ａから第１放熱部材３５Ａを介して第１冷却部材３１Ａに伝達される放熱経路Ｐ１と、負極集電タブ２５から第１放熱部材３５Ａを介して第１冷却部材３１Ａに伝達される放熱経路Ｐ２と、ラミネートフィルム２１の他面２１ｂから第２放熱部材３５Ｂを介して第２冷却部材３１Ｂに伝達される放熱経路Ｐ３と、正極集電タブ２３から第２放熱部材３５Ｂを介して第２冷却部材３１Ｂに伝達される放熱経路Ｐ４との４つの放熱経路で冷却部材３１に伝達されるので、効果的にラミネート電池セル２０の放熱を行うことができる。   In the laminated battery cell 20 configured in this manner, the heat generation path P1 in which the heat generated by the storage element 10 is transmitted from the one surface 21a of the laminate film 21 to the first cooling member 31A via the first heat radiating member 35A; Heat dissipation path P2 transmitted from the negative electrode current collecting tab 25 to the first cooling member 31A through the first heat dissipation member 35A, and from the other surface 21b of the laminate film 21 to the second cooling member 31B through the second heat dissipation member 35B.

［第３実施形態］
図７は、第３実施形態のラミネート電池モジュール４０の模式図である。なお、図７〜図９において、第１及び第２実施形態のラミネート電池セル２０と同一の構成要素については同一の符号を付して説明を省略する場合がある。 Third Embodiment
FIG. 7 is a schematic view of a laminate battery module 40 according to the third embodiment. In FIGS. 7 to 9, the same components as those of the laminate battery cell 20 of the first and second embodiments may be assigned the same reference numerals and descriptions thereof may be omitted.

ラミネート電池モジュール４０は、ラミネート電池セル２０を複数積層して構成される。ラミネート電池モジュール４０では、隣り合うラミネート電池セル２０のうち一方のラミネート電池セル２０の長手方向一方側が正極集電タブ２３、長手方向他方側が負極集電タブ２５の場合、他方のラミネート電池セル２０の長手方向一方側が負極集電タブ２５、長手方向他方側が正極集電タブ２３となるようにラミネート電池セル２０が並べられる。即ち、ラミネート電池モジュール４０では、長手方向一方側でも長手方向他方側でも、積層方向に沿って正極集電タブ２３と負極集電タブ２５とが交互に配列され、ラミネート電池セル２０が直列に接続されている。   The laminate battery module 40 is configured by laminating a plurality of laminate battery cells 20. In the laminate battery module 40, in the case where one longitudinal direction side of one laminate battery cell 20 of the adjacent laminate battery cells 20 is the positive electrode current collection tab 23 and the other longitudinal direction side is the negative electrode current collection tab 25, the other laminate battery cell 20 is Laminated battery cells 20 are arranged such that one side in the longitudinal direction is the negative electrode current collection tab 25 and the other side in the longitudinal direction is the positive electrode current collection tab 23. That is, in the laminated battery module 40, the positive electrode current collection tab 23 and the negative electrode current collection tab 25 are alternately arranged along the stacking direction on either side in the longitudinal direction or the other side in the longitudinal direction, and the laminated battery cells 20 are connected in series. It is done.

隣り合うラミネート電池セル２０間には、蓄電素子１０が発生する熱を放熱する冷却部材３１と、一端部が隣り合うラミネート電池セル２０のうち一方のラミネート電池セル２０の負極集電タブ２５に接続されるとともに、他端部が該一方のラミネート電池セル２０のラミネートフィルム２１と冷却部材３１との間に介在する放熱部材３５と、を備える。言い換えると、ラミネート電池セル２０が冷却部材３１によって両側から挟まれ、ラミネート電池セル２０の片側には負極集電タブ２５に接続された放熱部材３５が冷却部材３１との間に介在している。   The cooling member 31 for radiating heat generated by the storage element 10 is connected between adjacent laminate battery cells 20, and one end is connected to the negative electrode current collection tab 25 of one laminate battery cell 20 of the adjacent laminate battery cells 20. And a heat dissipation member 35 interposed between the laminate film 21 of the one laminate battery cell 20 and the cooling member 31 at the other end. In other words, the laminated battery cell 20 is sandwiched from both sides by the cooling member 31, and the heat dissipation member 35 connected to the negative electrode current collecting tab 25 is interposed between the laminated battery cell 20 and the cooling member 31 on one side.

A first heat dissipation member 35A connected between the laminate film 21 of the one laminated battery cell 20 and the cooling member 31 while being connected, and the other of the laminated battery cells 20 having one end adjacent thereto A second heat dissipation member 35B is connected to the positive electrode current collecting tab 23 of the laminate battery cell 20 and the other end is interposed between the laminate film 21 of the other laminate battery cell 20 and the cooling member 31. . In other words, the laminated battery cell 20 is sandwiched from both sides by the cooling member 31, and the first heat dissipation member 35 A connected to the negative electrode current collection tab 25 is interposed between the laminated battery cell 20 and the cooling member 31. A second heat dissipating member 35 B connected to the positive electrode current collecting tab 23 is interposed between the laminate battery cell 20 and the cooling member 31 on the opposite side.

図９を用いてより具体的に説明すると、ラミネートフィルム２１の一面２１ａには、第１放熱部材３５Ａを挟んで冷却部材３１が配置されている。第１放熱部材３５Ａは、一端部が負極集電タブ２５に溶接されるとともに、他端部がラミネートフィルム２１の一面２１ａと冷却部材３１との間に介在する放熱シート又は放熱プレートである。ラミネートフィルム２１の他面２１ｂには、第２放熱部材３５Ｂを挟んで冷却部材３１が配置されている。第２放熱部材３５Ｂは、一端部が正極集電タブ２３に溶接されるとともに、他端部がラミネートフィルム２１の他面２１ｂと冷却部材３１との間に介在する放熱シート又は放熱プレートである。   If it demonstrates more concretely using FIG. 9, the cooling member 31 will be arrange | positioned on the one surface 21a of the laminate film 21 on both sides of the 1st thermal radiation member 35A. The first heat dissipating member 35A is a heat dissipating sheet or a heat dissipating plate whose one end is welded to the negative electrode current collecting tab 25 and the other end is interposed between the surface 21a of the laminate film 21 and the cooling member 31. The cooling member 31 is disposed on the other surface 21b of the laminate film 21 with the second heat radiation member 35B interposed therebetween. The second heat dissipating member 35 B is a heat dissipating sheet or a heat dissipating plate whose one end is welded to the positive electrode current collecting tab 23 and the other end is interposed between the other surface 21 b of the laminate film 21 and the cooling member 31.

このように構成されたラミネート電池モジュール４０では、隣り合うラミネート電池セル２０間に冷却部材３１が設けられるので、１つの冷却部材３１によって両側のラミネート電池セル２０を冷却することができる。また、全ての第１放熱部材３５Ａは、一端部がラミネート電池セル２０の負極集電タブ２５に溶接されるとともに、全ての第２放熱部材３５Ｂは、一端部がラミネート電池セル２０の正極集電タブ２３に溶接されるので、両方の集電タブ２３、２５から積極的に放熱することができる。   In the laminated battery module 40 configured as described above, since the cooling members 31 are provided between the adjacent laminated battery cells 20, the laminated battery cells 20 on both sides can be cooled by one cooling member 31. Moreover, while all the 1st thermal radiation members 35A are welded to the negative electrode current collection tab 25 of the lamination battery cell 20 at one end part, the positive electrode current collection of the lamination battery cell 20 is one end part of all the 2nd thermal radiation members 35B. Since it is welded to the tab 23, heat can be actively dissipated from both current collecting tabs 23, 25.

The heat radiation path P2 transmitted to the cooling member 31 via the heat radiation path P3 transmitted to the cooling member 31 via the second heat radiation member 35B from the other surface 21b of the laminate film 21; Since the heat is transmitted to the cooling member 31 through the four heat radiation paths of the heat radiation path P4 transmitted to the cooling member 31 through the heat radiation member 35B, the laminated battery cell 20 can be effectively dissipated.
