    • There are provided an electrode assembly and a secondary battery using the same. An electrode assembly includes a first electrode plate having a first non-coating portion formed along one end portion in a length direction thereof; a second electrode plate having a second non-coating portion formed along the other end portion opposite to the first non-coating portion; and a separator interposed between the first and second electrode plates. In the electrode assembly, the first electrode plate, the second electrode plate and the separator are wound in a jelly-roll shape, and the electrode assembly further includes a clamping member that fixes at least one of the first and second non-coating portions. Accordingly, although the thickness of an electrode tab is increased, it is possible to simply manufacture high-power, high-capacity medium- and large sized batteries.
    • 提供电极组件和使用其的二次电池。 电极组件包括:第一电极板,其具有沿其长度方向的一个端部形成的第一非涂覆部分; 第二电极板,具有沿着与第一非涂覆部分相对的另一端部形成的第二非涂覆部分; 以及插入在第一和第二电极板之间的隔膜。 在电极组件中,第一电极板,第二电极板和隔板以胶卷形状卷绕,并且电极组件还包括固定第一和第二非涂覆部分中的至少一个的夹持构件。 因此,尽管电极片的厚度增加,但是可以简单地制造大功率,大容量的中型和大型电池。
