Abstract

An electrode assembly includes: an electrode plate which is wound together with an electrode plate having a different polarity and then formed in a form of a jelly roll and includes a plurality of non-coated portions that are spaced apart from each other; and a plurality of tabs attached to the plurality of non-coated portions, respectively, in which the plurality of non-coated portions includes a first non-coated portion having a set or predetermined width, and a second non-coated portion having a different width from the width of the first non-coated portion. According to the exemplary embodiments of the present invention, it is possible to more easily align and bond multiple tabs, and weld the multi-tab structure to a CID (or a can). Furthermore, it is possible to increase an output of a secondary battery by reducing resistance of the battery.
