    • Disclosed is a flat battery which includes power generating element 18 accommodated in an inner space formed by sealing outer peripheral edges of package members 16 and 17, collector 11a, 13a connected to an electrode plate of power generating element 18 and an electrode tab 14, 15 taken out from the outer peripheral edges of package members 16 and 17. Electrode tab 14, 15 has conducting portion 151 overlapping and joined to collector 11a, 13a and stress relieving portion 152 formed of a material having higher elasticity than that of conducting portion 151. It is thus possible to prevent the occurrence of wrinkles in collector 11a, 13a or electrode tab 14, 15 and separations in weld joints due to a difference in expansion/contraction rate between collector 11a, 13a and electrode tab 14, 15.
    • 公开了一种扁平电池,其包括容纳在通过密封封装构件16和17的外周边缘而形成的内部空间中的发电元件18,连接到发电元件18的电极板的集电体11a,13a和电极接头14,15 从封装构件16和17的外周边缘取出。电极接头14,15具有重叠并连接到集电体11a,13a和由具有比导电部分151的弹性高的材料形成的应力消除部分152的导电部分151。 因此,可以防止集电体11a,13a或电极片14,15的褶皱的发生,以及由于集电体11a,13a和电极片14,15之间的膨胀/收缩率的差异导致的焊缝的分离。
