相关专利申请的交叉参考
本申请所要求的权利要求以2004年9月22日递交韩国知识产权局的韩国专利申请No.10-2004-0076134为优先权并获益于该申请，该申请的全部内容通过引用被合并到本申请中。
技术领域
本发明涉及二次电池，尤其是用于容纳二次电池的袋、使用该袋的二次电池以及用于密封二次电池的装置。
背景技术
由于诸如摄录机、移动电话、便携式PC等便携式电子产品的广泛使用，能够用作这些便携式电子产品驱动电源的二次电池，已经逐渐变得重要。这是因为锂二次电池比诸如传统的铅蓄电池、镍镉电池、镍氢电池和镍锌电池等其他二次电池，每单位重量具有更大的能量密集度。另外，锂二次电池可以被快速地充电。由于所有这些原因，锂二次电池的使用明显增加。
锂离子电池根据所使用的电解液分类。锂离子电池使用液体电解液，和锂离子聚合物电池使用固体聚合物电解液。锂离子聚合物电池可以使用不包含液体电解液的全固体聚合物电解液，也可以使用包括一些液体电解液的凝胶型聚合物电解液。
使用液体电解液的锂离子电池，能够被容纳在被焊接密封的圆柱形或有角的金属罐中。这些罐型二次电池在形状上具有局限性，限制了利用这些电池作电源的电子产品的设计。另外，使用罐型二次电池，难于减小电子产品的体积。
针对这些局限性，袋型二次电池已经被开发作为罐型二次电池的备选方案，其中两个电极、一块隔板和电解液被容纳在一个包括膜的密封的袋中。
图1和图1A说明了典型的现有技术的袋型二次电池。如图1A所示，典型的锂离子聚合物电池的袋，具有包括聚烯烃热粘合层15、铝金属层13、水和氧气的阻挡层、尼龙层11和保护层的多层结构。其中，充当密封剂的聚烯烃热粘合层15具有热粘合性能；铝金属层13充当用于保持机械强度的材料。袋通过依次层压这些层而被形成。流延聚丙烯(CPP)通常被用作聚烯烃层。
如图1所示，袋包括具有腔室21的容器20和用于覆盖腔室21的盖10。电极组件30被容纳在腔室21中，并且包括阳极31、阴极35和隔板33。阳极31、阴极35和隔板33被层压及卷绕从而形成电极组件30。电极接线片37和38从阳极和阴极突起，而带39被附到每个接线片压在袋的容器20的唇缘23上的部分。
袋型二次电池是柔性的并且可以采用多种形状，使得制造具有相同容量而具有减少的体积和重量的二次电池成为可能。然而，与罐型二次电池不同，使用在袋型二次电池中的袋是柔软的，造成袋型二次电池不牢固，并且降低袋的密封的可靠性。因此，袋型二次电池主要和使用凝胶型或全固体聚合物电解液的锂离子聚合物电池一起使用，而不和使用液体电解液的、可能泄漏的锂离子二次电池一起使用。
电极组件被安置在袋型二次电池的袋中，因此正如对二次电池所要求的，小的袋能够具有大的容量。另外，由于唇缘23与电池的容量或电池的功能无关，需要减小围绕容器20的唇缘23的范围。当唇缘23被减小时，具有更大容量的电极组件能够被容纳在袋中，导致具有更大容量的二次电池。然而，由于盖10被密封到容器20的面积被减小，唇缘23的减小也降低了密封的可靠性。
然而，在盖10的热粘合聚烯烃层热熔到容器20的热粘合聚烯烃层的过程中，由于在热熔中施加的外部压力，一部分熔化的聚烯烃层从袋中渗出。 这种事件不利地影响袋的外观，并且减小熔化的聚烯烃层的厚度，从而降低密封的可靠性。此外，在密封过程中很多聚烯烃层可能从袋中渗出，从而露出聚烯烃层以下的金属阻挡层。这种事件造成袋和电极接线片之间的短路。
发明内容
本发明致力于提供一种用于容纳二次电池的袋。在通过包括在袋上加热和加压力的热熔密封中，该袋防止形成袋的树脂层尤其是热粘合层渗出袋。任凭袋的密封区域的减小，该袋还提高了密封的可靠性，并且给予增加的电池容量。
在本发明的另一实施例中，提供了一种用于密封袋的装置。该装置防止多层袋的至少一些树脂层在热熔中离开它们的原始位置。这个装置防止金属阻挡层暴露，从而防止短路。
根据本发明的一个实施例，一种用于二次电池的袋，包括在容器的唇缘和盖的边缘两者中至少一个之上的多个凹槽。一旦密封，至少一些凹槽被填充热粘合层的树脂。凹槽能够采用点或线的形状，并且可以被仅形成在密封区域或者包括密封区域的袋的容器的整个表面。
凹槽可以被排列在袋的盖和容器上，因此，在盖上的凹槽与在容器上的凹槽相互重叠。另一方面，在盖上的凹槽对应于在容器上的凹槽，因此热粘合层的树脂形成粘合芯。
在本发明的另一实施例中，二次电池包括具有被隔板隔开的正负电极的电极组件。电极和隔板被层压以形成电极组件，其被容纳在包括两或更多层的袋中。凹槽被形成在袋的容器和袋的盖两者中至少一个之上，并且一旦密封该袋，至少一些凹槽被填充有热粘合层的树脂。
在一个实施例中，凹槽仅被形成在袋的盖和袋的容器两者中的一个之上，并且厚的热粘合层被形成在袋的盖和容器两者中的另一个之上。
根据本发明的另一实施例，一种用于密封二次电池的袋的装置，包括密封夹具或密封模具，其在袋的密封区域上加压，从而密封该袋。例如，密封 夹具的一个表面接触袋的盖的顶面，而另外一个表面接触容器唇缘的底面。通过向密封夹具的表面加热和加压来密封袋。在一个实施例中，夹具在其表面具有至少一个孔，因此一旦向袋加压，空气通过孔被排出。

具体实施方式
现在将参照附图详细描述本发明的示例性实施例。在描述中，为了避免相同或相似成分的重复描述，类似的参考标号被用于识别类似的成分。
在本发明的一个实施例中，用于容纳二次电池电极组件的袋100，包括 容器120和盖110。容器120包括唇缘123和用于容纳电极组件的腔室121。盖110适合于容器120，并且具有与容器的唇缘123重叠的部分。如图2所示，凹槽117被形成于袋100的密封区域。密封区域包括容器120的唇缘123和盖110的与唇缘123重叠的部分。
容器120的腔室121可以通过模压多层膜而被形成。气室可以在腔室的侧面上形成，用于除去由最初老化或充电、放电产生的气体。位于密封区域的凹槽117，可以在腔室121的形成之外被另行形成。另一方面，凹槽117可以与腔室121同时通过模压被形成，从而降低处理时间和成本。凹槽117可以采用任何合适的形状。例如，凹槽可以是如图5所示的点状，或者它们可以包括如图2、4和6所示的线形槽。
如图2A和2B所示，根据本发明一个实施例的二次电池，包括容纳在袋中的电极组件130，该袋包括容器120和盖110。电极组件130包括阳极131和阴极135，其中每个通过用电极活性材料填充栅格或用电极活性材料涂覆薄膜而被形成。阳极131、阴极135和被安置于阳极和阴极之间的隔板133，被层压和卷绕以形成胶卷形结构。除了使用全固体聚合物电解液的锂离子聚合物电池，电极组件的胶卷型隔板被浸泡了电解液。使用全固体聚合物电解液的锂离子聚合物电池，不需要这种额外的电解液浸泡，因为这种电池中的隔板包括了电解液。电极组件130被容纳在袋的容器121中。
电极接线片137和138分别被附在阳极131和阴极135上，并且彼此被隔开预定的距离。电极接线片将电极组件电连接到外部电源上。另外，热粘合带139可以被附在电极接线片37和38与袋的容器120的唇缘123重叠的部分。这些带139使电极接线片139能够更好地粘合到袋上。
在本发明的一个实施例中，袋包括三层。然而，可以理解，更多的层可以被提供。另外，袋的层可以包括与具体描述不同的材料。例如，流延聚丙烯(CPP)热粘合层115另一方面可以包括从包含如下材料的组中选择的材料：氯丙烯、聚乙烯、乙烯丙烯共聚物、聚乙烯和丙烯酸的共聚物以及聚丙烯和丙烯酸的共聚物。
袋包括尼龙层111、流延聚丙烯层115和铝层113。整个袋的厚度为从约40至约120微米。尼龙层111和CPP层115各自具有从约10至约40微米的厚度。铝层113的厚度为从约20至约100微米。
在如图3B所示的一个实施例中，每个凹槽217的的深度约为100微米，并且通常对应于袋的厚度。在如图3A所示的另一实施例中，凹槽317仅在热粘合层中被形成，并且每个凹槽为约10至约40微米深，通常对应于热粘合层315的厚度。
每个凹槽可以具有任何合适的横截面形状，例如半圆形或三角形，因此凹槽很容易被形成。每个凹槽的宽度可以等于它的深度。凹槽的深度可以通过控制凹槽之间的距离以及热熔期间的温度和压力而被控制。另外，热熔期间的温度和压力能够通过控制凹槽之间的距离和凹槽的深度而被控制。控制这些参数是必要的，从而确保热粘合层不会从袋中渗出。
图4是根据本发明一个实施例的密封的二次电池400的透视图。如同所示，凹槽417在形状上是线形的，并且仅被形成在袋的密封区域上，例如，凹槽417被形成在袋的容器的唇缘423上以及袋的盖的与唇缘423重叠的部分上。在此实施例中，在袋的盖上的每个凹槽在位置上对应于在容器的唇缘423上的凹槽的位置。
在密封袋时，大部分凹槽417被填充部分在热量和压力的施加中离开原始位置的热粘合层。在凹槽中的热粘合层然后被冷却和硬化，从而形成硬的密封。
图5是根据本发明另一实施例的密封的二次电池500的透视图。在此实施例中，凹槽517是点状的，并且通过模压被形成。为了提供热粘合层的空间，点状凹槽517的间距比线形凹槽417的间距更大。
图6是根据本发明再一实施例的密封的二次电池600的透视图。与图4和5不同，在此实施例中的凹槽617在形状上是线形的，并且被形成在包括密封区域的袋的整个盖上。另外，凹槽617可以被形成在包括腔室的容器的整个表面上，或者仅仅在容器的唇缘上。根据此实施例，由于凹槽不需要被 单独形成，二次电池的加工被简化。然而，可以理解，过剩的热粘合层仅填充在密封区域的凹槽。
图7是根据本发明又一实施例的袋的密封区域的局部截面图。当袋的盖被密封到容器的唇缘时，凹槽被填充入热粘合层715，产生粘合芯753。
如图7所示，在热熔过程中，压力被施加到凹槽上，导致过剩的热粘合层715填充到凹槽中。在袋的容器的唇缘上的凹槽和在袋的盖上的凹槽在位置上相对应，因此一旦冷却和硬化就在凹槽内产生粘合芯753。
图8是根据本发明一个实施例的安置于密封装置中的袋的密封区域的局部截面图。密封装置可以包括袋的密封区域被插入其中的夹具或者模具。密封夹具和密封模具的结构是公知的。
参照图8，电极组件(未示出)被安置在袋的腔室中，并且腔室被袋的盖覆盖。密封区域于是被置于密封装置的第一板850a和第二板850b之间。密封装置然后被用于加热和加压于袋的密封区域，从而密封此袋。尽管没有示出，密封装置包括用于加热该装置的第一板850a和第二板850b的加热器。密封装置还包括诸如虎钳的装置，用于共同加压于该装置的第一板850a和第二板850b。
在一个实施例中，至少一个、优选是多个凹槽851被形成在接触袋的密封区域的第一板850a和第二板850b上。一旦加压，尼龙层811、金属阻挡层813和热粘合层815部分地熔化，变得柔软，并且渗入位于密封装置的板850a和852b中的凹槽851。结果，袋的一部分会比层的其余部分更厚。特别地，当热粘合层815收集在板850a和850b的凹槽851中，粘合芯被产生，从而增强袋的密封。密封的袋可以具有如图4或5所示的外观。
在如图9所示的另一实施例中，凹槽951被形成于第一板950a和第二板950b的区域，其接触袋的密封区域。另外，通常位于凹槽951的区域的孔953，被提供在板950a和950b中。一旦加压，压缩在凹槽951内的空气可以通过孔953排出，防止凹槽951中的压力增加，并且能够使得在凹槽951中热粘合层915的树脂的收集变得容易。
根据本发明的一个实施例，热粘合层在密封中依照热粘合层的热熔和加压被形成在凹槽中。这种结构防止熔化的热粘合层泄漏到袋外面，从而提高粘合力。根据本发明的另一实施例，密封装置的板包括用于在密封中收集融化的层的凹槽。这种结构防止部分熔化的树脂泄漏到袋外面，并且防止袋的外观的损坏。另外，部分收集的熔化的树脂，提高袋的密封。因此，任凭袋的密封区域的减小，本发明的袋提高袋的密封的可靠性，从而增加电池容量。
仅为了说明性的目的，描述本发明示例性的实施例。熟悉本领域的技术人员应能理解，在不背离如所附权力要求公开的发明的范围和精神的前提下，各种修改、增添和等价替换都是可能的。
