    • 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.
    • 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。
