<p>PROBLEM TO BE SOLVED: To provide an electrode assembly of a secondary battery capable of stacking a first electrode tab and a second electrode tab at desired positions, respectively, without a process of removing a non-overlapped portion of the first electrode tab and the second electrode tab.SOLUTION: In an electrode assembly of a secondary battery, first and second electrode plates are sequentially stacked, and a first separation membrane is interposed between the first and second electrode plates to be wound. The first electrode plate has one surface on which first electrode tabs are formed and an other surface on which the first electrode tabs are not formed. The second electrode plate has one surface on which second electrode tabs are formed and an other surface on which the second electrode tabs are not formed. The first and second electrode plates further include a stacking surface formed between the one surface and the other surface thereof and having a width increased by a predetermined interval whenever they are wound.</p> |
