摘要： The present invention relates to a electrode stacking method, wherein electrodes are stacked in such a manner that the electrodes are disposed to face each other on both sides of a separation layer to which predetermined tension force is applied along the longitudinal direction of said separation layer, and the electrode assembly is turned so that another separation layer is formed outside the electrodes. According to the rechargeable lithium ion batteries in accordance with the present invention, the electrode stack in which the arrangement of anode electrodes and cathode electrodes is not disordered because uniform stress is applied to the entire battery and the separation layer maintains a constant tension force can be fabricated. Accordingly, the lifespan of a rechargeable lithium ion battery can be increased, and the input and output characteristic of the battery can be improved.
摘要翻译：电极堆叠方法技术领域本发明涉及一种电极堆叠方法，其中电极以这样的方式堆叠，使得电极在沿着所述分离层的纵向方向施加预定张力的分离层的两侧彼此面对，并且电极组件被转动，使得在电极外部形成另一个分离层。根据本发明的可再充电锂离子电池，由于均匀的应力施加在整个电池上并且分离层保持恒定的张力，因此阳极电极和阴极电极的布置不会导致排列紊乱的电极堆叠制造。因此，可以提高可充电锂离子电池的使用寿命，能够提高电池的输入输出特性。

摘要： Disclosed herein is a unit cell for a lithium ion secondary battery, which includes an electrode laminate formed in such a manner that a plurality of unit structures are stacked, each of which includes and least one electrode and at least one separation layer; and at least one conductive sheet layer located between certain layers in the electrode laminate and electrically connected to an electrode lead. The conductive sheet layer of the unit cell for the lithium ion secondary battery rapidly conducts current to the outside or generates heat in quantity smaller than the quantity of heat generated in positive and negative electrodes when short-circuit occurs due to a physical or electrical impact applied to the battery. Accordingly, it is possible to reduce the risk of firing or explosion due to the physical or electrical impact to improve the safety of the lithium ion secondary battery.
摘要翻译：本发明公开了一种用于锂离子二次电池的单元电池，其包括以多个单元结构堆叠的方式形成的电极层压体，每个单元结构包括至少一个电极和至少一个分离层; 以及位于所述电极层叠体中的某些层之间并电连接到电极引线的至少一个导电片层。用于锂离子二次电池的单元电池的导电片层在由于施加的物理或电子冲击而发生短路时迅速地将电流传导到外部或产生小于正极和负极中产生的热量的热量到电池。因此，可以降低由于物理或电气冲击引起的烧毁或爆炸的风险，以提高锂离子二次电池的安全性。

摘要： The present invention discloses a crude cell for a large secondary battery comprising unit cells alternately stacked in the fold/fold type or a crude cell for a large secondary battery comprising unit cells wound and stacked in the jelly roll type, each unit cell having an anode, a cathode and a separator, in which a polymer film is inserted in the crude cell to support the crude cell. According to the present invention, it is possible to prevent structural distortion caused by external impact and self reaction of the crude cell by firmly supporting the crude cell. Consequently, it is possible to prevent short of the anode and the cathode in the crude cell by electrical connection and to improve interfacial properties of the anode, the cathode and the separator.
