Description

用于成形扁平原电池的装置
技术领域
本发明涉及一种成形扁平原电池的装置，后文中也叫扁平电池。
背景技术
在很多情况下，可充电原电池，具体而言是锂离子电池，包含由多个单个元件组成的电池组。组装成这样的电池组的单个电池或单个元件是由导电体、活性电极膜以及隔板形成的叠层。包括永久性连接的单个部件的这种叠层(这也叫做双电池)以这种形式制造，具体而言以这种可能的顺序制成：负极-隔板-正极-隔板-负极或正极-隔板-负极-隔板-正极。
美国专利5460904公开了一种制造这种可充电锂离子电池的方法。在这些方法中，如果需要的话，活性材料和附加剂，如电极中的导电增强剂或隔板中的稳定剂、特定的共聚物，如聚偏氟乙烯-六氟丙烯(PVDF-HFP)，和增塑剂的部分，在很多情况下为酞酸二丁脂(DBP)，在添加丙酮以释放该共聚物后被完全混合并被拉成薄片。以这种方式形成的电极膜和隔板膜经几个层叠加工过程被处理成上述双电池。然后将几个双电池一个叠在另一个的顶上以形成叠层。该叠层被插入一容器，例如，该容器由深拉分层的铝片制成，该容器充满了电解质，用罩密封，设置了叠层，用一端封密封，将最终的组件制成最终电池。
成形大量这种扁平电池要求精心设计的装置，在该装置中，导电体或电池电接线端在成形过程中形成电接触，并且电池被固定就位。例如，如果这种类型的扁平电池平躺并靠在各电池上设置的导电体上，它们的触针将压靠在它们上面。如果导电体的结构或间隙改变，则必需进行精细的改造和调整。
发明内容
本发明的目的是要形成一种装置，该装置用于成形大量扁平原电池，具体而言是例如锂离子电池的扁平电池，该装置适用于均匀地让大量元件经受成形处理，并且特别是将允许形成具有各种构造的导电体连接片的元件而无需改造。
本发明通过形成具有权利要求1所述特征的用于成形扁平原电池特别是锂离子电池的装置来解决该问题。在从属权利要求中描述了本发明的优选实施例。通过明显参照方式，将权利要求书中的措词作为本说明书的组成部分。
根据本发明，将大量扁平元件一个接一个地插入该装置中的凹槽内，所述凹槽适合与电池的横截面相配，其中在扁平元件上的导电体连接片指向同一方向并靠在接触件上，该接触件被设置在支架上并优选为板的形式。导电体连接片也可以夹持在所述接触件之间。这些接触件具体是位于导电体连接片的两侧，并具有比导电体宽得多的接触表面。它们可以是接触弹簧。原电池可以是开端型的锂离子电池。
根据本发明的装置将根据附图在下面详细说明，附图已经被限定为示意性的表示。
附图说明
图1表示用于接触扁平电池的传统的方式；
图2、3和4表示根据本发明的接触件结构；和
图5表示根据本发明的成形装置。
具体实施方式
图1表示具有通过与示意性表示的电源4相连的触针3以传统方式接触的导电体连接片2的扁平电池1。
图2表示具有设置在支架5、6之间的导电体2的同样的扁平电池1，所示支架5、6处于它们的敞开位置。这些支架5、6中的至少一个带有接触弹簧7。这些接触弹簧7具有大的接触面积，并且可以压靠在导电体连接片2的两侧。如图3和4所示，这些接触弹簧7的大接触面积允许在同一装置上检查各种各样的不同类型的电池。即，可以在不更换接触弹簧7的情况下，适应大量不同的导电体间隔。正如从图3和4所示的例子所看到的，间隔很接近的导电体连接片2和间隔很宽的导电体连接片2可以使用同样的接触弹簧7进行接触。
图5表示根据本发明的成形装置，该成形装置是将大量扁平电池1一个接一个排列的支架8。各扁平电池1被安置在支架8的凹槽中，使该凹槽适合与电池的横截面相配。它们的导电体连接片2被设置成所有导电体连接片2都指向同一方向，具体而言是指向上方。在成形过程中，要将这些电体连接片2夹持在大面积的接触弹簧7之间。
如上所述，依照本发明的接触弹簧7的大接触面积允许接触具有各种尺寸的各种各样的扁平电池，且允许导电体连接片具有不同间隔。其消除了对附加接触单元的基本投资和仓库贮存这种单元的成本的要求。此外，在制造工作中没有过长的准备时间，并且该成形装置灵活地使自身适应各种电池结构。接触导电体连接片的两侧使其在不占太多空间的情况下可以可靠地接触它们。
