Description
本发明涉及在很狭的间隙内配置大容量的电气双层电容器单元的构造。
电气双层电容器的容量比其他电容器的容量大,现一直用于待用的电源等。
图6表示已有的电气双层电容器单元(以下有时简称“电容器单元”)。在图6中C为电容器单元,1为集电电极、2为封口材料、3为电极层、4为多孔隔离层。
封口材料2为筒状,多孔隔离层4配置在封口材料2的内部的大致中央的部位上。又在多孔隔离层4的两侧充填电极层3,并设置集电电极1以覆盖电极层3的表面和封口材料2的边缘。
集电电极1可用例如导电橡胶薄板、封口材料2可用例如非导电橡胶,多孔隔离层4可用例如聚丙烯的多孔膜。又,电极层3可用由活性炭(粒子)和稀硫酸混合后作成的糊状物。
图7表示将多个上述的单元C集合起来而形成的已有的电气双层电容器。图7中,5为壳体,6、7为电极板,6-1、7-1为端子,8为绝缘板,9、10为加强板,C为电容器单元。
加强板9和电极板7相连,加强板10经壳体5与电极板7相连,端子6-1是将电极板6的一部分切开后竖起来的。端子7-1是将电极板7的一部分切开后竖起来的。绝缘板8是为了使电极板6、7之间绝缘而插入的。
在简单地进行层叠的情况下因单元C的活性炭粒子的接触电阻大,故电容器的内阻大。因而,在层叠时通过壳体5的开口边缘部分卷起向层叠体施加压力,使上述接触电阻变小,从而使电容器的内阻减小。
在上述例子中不是在单个电容器单元阶段加压,而是在层叠后的多个电容器单元阶段加压,而也有如下面所示对单个电容器单元进行加压处理的例子。
图8为作成钮扣形的电气双层电容器的单元。图8中,11、12为集电电极、13为电极层、14为多孔隔离层、15为封口材料、16为绝缘材料。
集电电极12成圆筒状,其中装有电极层13、多孔隔离层14、封口材料15等,通过用集电电极11压在他们的上面,并使集电电极12的开口边缘部分向内侧弯曲变形而制成电容器单元。通过使集电电极12卷曲变形的力进行加压,使内阻变小。
图9为将钮扣形电容器单元层叠起来而形成的电气双层电容器。为了得到所希望的电压而将必要个数的电容器单元层叠起来并装入外壳17内。在这个阶段只要确保电气的接触良好,而不需要加压。
如上所述,在已有的电气双层电容器中,是将电容器单元层叠起来进行配置的。
又与电气双层电容器有关的已有的文献有例如特开昭56-2621号的公报等。
但是存在的问题是在要求将大容量的电气双层电容器装到很狭小的间隙内时,用已有的方式对电容器单元进行层叠的作法,不能满足上述的要求。
例如在要将电气双层电容器装到构成汽车壁的板和板之间等的狭小的间隙内时,如用已有的层叠结构则厚度变大,而不能装入该间隙。
本发明的目的是为了解决上述问题。
为了解决上述课题,本发明的电气双层电容器单元的配置构造是在板状体的表面上不导电地贴上第1极板,在该第一极板上导电地贴上电气双层电容器单元,在该电气双层电容器单元之上导电地贴上第2极板。
如采用上述配置构造,则即使空间狭小,只要有面积,就可以配置很多的电容器单元。
从而,可利用原来不能有效地利用而放置着的狭小空间来装上大容量的电容器。
下面根据附图对本发明的实施例进行详细说明。
图1表示本发明的电气双层电容器单元的配置构造的分解透视图,图2表示其断面图。在这些图中,20为板状体,21为粘接剂,22、24为极板,23为导电性接合材料,C为电容器单元,L为引线。
板状体20为例如构成汽车的壁的板等。首先,用粘接剂21将极板22贴到板状体20的表面上。接着,将电容器单元C经导电性结合材料23贴到极板22上。最后仍经导电性结合材料23将极板24贴到电容器单元C上。且可以根据需要,用其曲面与板状体20相同的非导电性的板材从极板24上推压。引线L从极板22、24处引出。
在近处有导电的器具时,为了避免和其接触,在如上所述贴好之后涂上绝缘材料,或用绝缘材料覆盖。
在本发明中由于不是将电容器单元C层叠起来进行配置的,而是通过粘贴成平面状而配置成的,故所需要的空间的厚度仅比一个电容器单元C的厚度厚些即可。因而即使间隙狭小,仍能装上大容量的电气双层电容器。
极板22、24可用例如铜板或不锈钢板。而当板状体20成曲面时,极板最好是薄板以便可以沿板状体2的曲面紧密地张贴。
又,当板状体20为导电性材料时粘接剂21应使用非导电性的。
在上例中所表示的为在极板22、24之间并联两个电容器单元,而如下所示,在配置时可适当确定电容器单元C的连接关系。
图3表示根据本发明的配置构造的串并联连接构成。其符号与图1的符号相对应。又25为极板。
使贴有极板24的3个电容器单元C作并联连接,贴有极板25的2个电容器单元C也作并联连接。这2个并联连接体经共用的极板22接成串联。
因而,等效电路如图4所示,可在所要的耐电压下得到所要的容量的电容器。图4中的符号22、24、25与图3中的符号相对应。
图5表示使电容器单元C在板状体20上的安装更牢固的手段的图。图5中的符号与图1对应。26为紧固用具,27为孔。所开的孔27要避开电容器单元C,并贯穿板状体20,极板22、24等。将紧固用具26压入此孔27内,并通过将极板24推压到板状体20一侧而紧固在一起。
这样,电容器单元C和板状体20非常牢固地装在一起,同时由于增大施加到电容器单元C上的压力,而使电容器的内阻减小。
如上所述,根据本发明的电气双层电容器单元的配置构造,即使空间很狭小,但只要有面积,就可以配置很多的单元。
为此,可以利用原来不能有效地利用而放置着的狭小空间(例如汽车的壁间的空间)来放置大容量的电容器。
