Further, the exemplified cutting position K is the boundary of the metal layer 7, but as long as the metal layer 7 does not span the two tab leads, the exposed portion of the flat conductor 11 may be cut with a certain amount of margin.
该极耳引线3在后述的方式中密封在非水电解质电池等中，但成为下述方式，即在以扁平导体11作为基础的扁平的引线导体(以下，称为引线导体)5的中间部的两面上，粘贴绝缘树脂膜6而作为密封部，且在露出到外部一侧的端部具有由易于软钎焊的金属材料构成的金属层(软钎焊连接部)7。而且，如作为上述主要的特征而说明的那样，软钎焊连接部7和绝缘树脂膜6之间的间隔d大于或等于2mm。The tab lead 3 is sealed in a non-aqueous electrolyte battery or the like in a manner to be described later, but is formed in the middle of a flat lead conductor (hereinafter referred to as a lead conductor) 5 based on the flat conductor 11 . On both sides of the portion, the insulating resin film 6 is attached as a sealing portion, and a metal layer (softened joint portion) 7 made of a metal material which is easily soldered is provided at an end portion exposed to the outside.

参照图2A、图2B，对将极耳引线3密封在锂离子电池等非水电解质电池中时的安装状态进行说明。图2A是表示使用了图1C的引线部件(极耳引线)3的非水电解质电池的一个例子的剖面图，图2B是表示在该非水电解质电池中将引线部件3弯曲的状态的剖面图。The mounting state when the tab lead 3 is sealed in a nonaqueous electrolyte battery such as a lithium ion battery will be described with reference to FIGS. 2A and 2B. 2A is a cross-sectional view showing an example of a non-aqueous electrolyte battery using the lead member (pole lead) 3 of FIG. 1C, and FIG. 2B is a cross-sectional view showing a state in which the lead member 3 is bent in the non-aqueous electrolyte battery. .
在图2A中例示的非水电解质电池1构成为：将隔着隔膜而层叠的正极板和负极板以及电解液收容在由包含金属箔的多层膜构成的外装体2中，将正极侧的极耳引线3和负极的极耳引线(未图示)经由绝缘树脂膜6而密封封装在外装体2的密封部2d上，并从外装体2取出。The nonaqueous electrolyte battery 1 illustrated in FIG. 2A is configured such that a positive electrode plate and a negative electrode plate laminated with a separator and an electrolytic solution are housed in an exterior body 2 composed of a multilayer film including a metal foil, and the positive electrode side is provided. The tab lead 3 and the tab lead (not shown) of the negative electrode are sealed and sealed on the sealing portion 2d of the exterior body 2 via the insulating resin film 6, and taken out from the exterior body 2.
在非水电解质电池1中，正极侧的极耳引线3的导体由于要施加高电位，因此由在高电位下不会溶解在电解液中的金属材料，即铝或者铝的合金形成，未图示的负极侧的极耳引线大多使用镀镍铜。此外，在双电层电容器中，正极侧、负极侧的极耳引线的导体均使用铝或者铝的合金。因此，即使负极侧的极耳引线，也能够使用如极耳引线3 所述的构造。In the nonaqueous electrolyte battery 1, the conductor of the tab lead 3 on the positive electrode side is formed of a metal material which is not dissolved in the electrolytic solution at a high potential, that is, an alloy of aluminum or aluminum, because a high potential is applied. Most of the tab leads on the negative side are nickel-plated copper. Further, in the electric double layer capacitor, an alloy of aluminum or aluminum is used for the conductors of the tab wires on the positive electrode side and the negative electrode side. Therefore, even the tab lead on the negative side can be used as the tab lead 3 The configuration described.
外装体2成为非水电解质电池1的外装壳体，例如通过将矩形的2片多层膜周边的密封部2d利用热熔接而密封，由此进行密封。绝缘树脂膜6通过预先热熔接而与正极的极耳引线3、负极的极耳引线接合。该绝缘树脂膜6和外装体2的多层膜被热熔接，这些极耳引线被密封封装。The exterior body 2 is an exterior case of the nonaqueous electrolyte battery 1, and is sealed by, for example, sealing the sealing portion 2d around the two rectangular multilayer films by heat welding. The insulating resin film 6 is bonded to the tab lead of the positive electrode and the tab wire of the negative electrode by thermal fusion bonding in advance. The insulating resin film 6 and the multilayer film of the exterior body 2 are thermally welded, and these tab leads are hermetically sealed.
正极侧的极耳引线3是从带卷状部件10b切出的，如图1C所示，通过如下过程而形成，即，形成将铝导体切断为长方形的引线导体5，并在该引线导体5的两面上从外装体2的取出部分处贴合2片绝缘树脂膜6。而且，向外装体2的外侧露出的部分，即在形成与外部电连接的部分处，以绝缘树脂膜6作为边界的一方的端部侧，具有由能够进行软钎焊连接的金属层构成的软钎焊连接部7。其中，如上述所述，设为上述边界和软钎焊连接部7具有大于或等于2mm的间隔d。以绝缘树脂膜6作为边界的另一方的端部侧保持铝导体的状态与电池内的电极板引线8连接。The tab lead 3 on the positive electrode side is cut out from the tape-like member 10b, as shown in Fig. 1C, by a process of forming a lead conductor 5 which cuts an aluminum conductor into a rectangular shape, and at the lead conductor 5 Two insulating resin films 6 are bonded to the removed portions of the exterior body 2 on both sides. Further, a portion exposed to the outside of the outer casing 2, that is, a portion on the side where the insulating resin film 6 is bordered on the portion electrically connected to the outside, has a metal layer which can be soldered. The joint 7 is soldered. Here, as described above, it is assumed that the boundary and the solder joint portion 7 have an interval d of 2 mm or more. The state in which the aluminum conductor is held on the other end side of the boundary with the insulating resin film 6 is connected to the electrode plate lead 8 in the battery.
绝缘树脂膜6例如能够由在引线导体5上粘接或者焊接的内侧层6a、以及与外装体2熔接的外侧层6b这2层形成。内侧层6a预先通过热熔融而与引线导体5密接，并对导体进行封装。外侧层6b使用熔点高于内侧层6a的熔点的材料，在进行与引线导体5的封装时，保持形状。而且，在与外装体2的密封时，能够通过使外侧层6b和外装体2熔接，而外装体2内的金属箔层2b和引线导体5不会发生电短路。绝缘树脂膜能够设为一层或者三层的结构。在三层的情况下，将中间层的熔点设为高于两面的层(外层或者内层)的熔点。The insulating resin film 6 can be formed, for example, of two layers of the inner layer 6a bonded or welded to the lead conductor 5 and the outer layer 6b welded to the outer casing 2. The inner layer 6a is in close contact with the lead conductor 5 by heat fusion in advance, and encapsulates the conductor. The outer layer 6b is made of a material having a melting point higher than the melting point of the inner layer 6a, and retains its shape when it is packaged with the lead conductor 5. Further, at the time of sealing with the exterior body 2, the outer layer 6b and the exterior body 2 can be welded, and the metal foil layer 2b and the lead conductor 5 in the exterior body 2 are not electrically short-circuited. The insulating resin film can be formed in one layer or three layers. In the case of three layers, the melting point of the intermediate layer is set to be higher than the melting point of the two layers (outer layer or inner layer).
形成外装体2的多层膜至少由3层的层叠体构成，该最内层膜2a作为不会溶解在电解液中且适合于防止电解液从密封部2d漏出的材料，使用聚烯烃树脂(例如：马来酸酐改性的低密度聚乙烯或者聚丙烯)。金属箔层2b使用铝、铜、不锈钢等的金属箔，提高对电解液的密封性。最外层膜2c是用于保护较薄的金属箔层2b的结构，由聚对苯二甲酸乙二醇酯(PET)等形成。The multilayer film forming the exterior body 2 is composed of at least three layers of a laminate which is a material which does not dissolve in the electrolytic solution and is suitable for preventing leakage of the electrolytic solution from the sealing portion 2d. For example: maleic anhydride modified low density polyethylene or polypropylene). The metal foil layer 2b is made of a metal foil such as aluminum, copper or stainless steel to improve the sealing property to the electrolytic solution. The outermost layer film 2c is a structure for protecting the thin metal foil layer 2b, and is formed of polyethylene terephthalate (PET) or the like.
上述的非水电解质电池1具有例如连接在实际使用时进行电池温 度的监视、充放电的控制而保护电池的保护电路基板(未图示)而设为一体的情况，或将多个电池的正极侧的极耳引线3和负极侧的极耳引线串联地电连接而使用的情况等。即使在如上所述的情况下，如果使用具有能够进行软钎焊的软钎焊连接部7的铝的极耳引线，则也能够通过软钎焊连接在上述保护电路基板上的保护电路的导体图案上，容易进行组装。The above nonaqueous electrolyte battery 1 has, for example, a battery temperature for connection in actual use. The monitoring of the degree of charge, the control of charge and discharge, and the protection of the protective circuit board (not shown) of the battery are integrated, or the tab lead 3 on the positive side of the plurality of batteries and the tab lead on the negative side are electrically connected in series. Connection and use, etc. Even in the case as described above, if the tab wire of aluminum having the solder joint portion 7 capable of soldering is used, the conductor of the protective circuit which can be connected to the above-mentioned protective circuit substrate by soldering can be used. Easy to assemble on the pattern.
而且，极耳引线3利用上述主要的特征，在如图2B例示那样弯折而使用时，也能够在引线导体5露出的部分处弯折，因此能够避免如软钎焊连接部7剥落而飞落的情况。另外，扁平导体11的厚度是0.1mm～0.2mm左右等，只要以与间隔d相对应而只在露出部分处弯折的方式适当决定即可。Further, the tab lead 3 can be bent at a portion where the lead conductor 5 is exposed when it is bent and used as illustrated in FIG. 2B. Therefore, it is possible to prevent the solder joint portion 7 from being flake off. The situation of falling. In addition, the thickness of the flat conductor 11 is about 0.1 mm to 0.2 mm, and may be appropriately determined so as to be bent only at the exposed portion in correspondence with the interval d.
此外，在图2A、图2B中例示的极耳引线3不限于从图1B中例示出的带卷状部件10b中切出的结构，也可以是逐一制造的结构。此外，也可以如在专利文献2中记载所述，使扁平导体11平行排列多个而行进，将绝缘树脂膜6跨越该多个扁平导体11(横切多个扁平导体11)而从两面粘贴。通过采用如上所述的方法，尤其能够将上述间隔d高精度地保持为恒定。另外，软钎焊连接部7的形成易于在贴合绝缘树脂膜6之前进行，但也可以在贴合后进行。Further, the tab lead 3 illustrated in FIGS. 2A and 2B is not limited to the structure cut out from the rolled member 10b illustrated in FIG. 1B, and may be manufactured one by one. In addition, as described in Patent Document 2, the plurality of flat conductors 11 may be arranged in parallel and travel, and the insulating resin film 6 may be pasted from both sides across the plurality of flat conductors 11 (transversely intersecting the plurality of flat conductors 11). . By adopting the method as described above, in particular, the above-described interval d can be kept constant with high precision. Further, the formation of the solder joint portion 7 is easy to be performed before the insulating resin film 6 is bonded, but it may be performed after bonding.
优选将多个扁平导体并行排列而集中地粘贴绝缘树脂膜(多个扁平导体利用绝缘树脂膜架桥)。在扁平导体的长度方向以恒定的间隔多处粘贴绝缘树脂膜。It is preferable that a plurality of flat conductors are arranged in parallel to collectively adhere an insulating resin film (a plurality of flat conductors are bridged by an insulating resin film). An insulating resin film is attached at a plurality of places at a constant interval in the longitudinal direction of the flat conductor.
而且，对绝缘树脂膜进行切断，而能够得到在一个扁平导体上多处粘贴有绝缘树脂膜的带卷件。Further, the insulating resin film is cut, and a tape wound member in which an insulating resin film is adhered to a plurality of flat conductors can be obtained.
在与绝缘树脂膜相距一定距离(例如2mm)的部位处设置软钎焊用金属层(冷喷涂等)。如果软钎焊用金属层与绝缘树脂膜的距离小于2mm，则在绝缘树脂膜上粘附金属而绝缘树脂膜的厚度发生变化，绝缘性劣化而不优选。A soldering metal layer (cold spray or the like) is provided at a portion spaced apart from the insulating resin film by a certain distance (for example, 2 mm). When the distance between the soldering metal layer and the insulating resin film is less than 2 mm, the metal is adhered to the insulating resin film, and the thickness of the insulating resin film changes, and the insulating property is deteriorated, which is not preferable.
此外，要求从绝缘树脂膜到软钎焊用金属层为止的间隔在各部位处恒定。在多个扁平导体上集中地粘贴绝缘树脂膜的情况下，在粘贴绝缘树脂膜之后再将金属层设置在各扁平导体上的方法容易将从绝缘 树脂膜到金属层为止的距离设为恒定。Further, the interval from the insulating resin film to the metal layer for soldering is required to be constant at each portion. In the case where an insulating resin film is collectively attached to a plurality of flat conductors, the method of disposing the metal layer on each of the flat conductors after the insulating resin film is pasted is easy to be insulated. The distance from the resin film to the metal layer was made constant.
