PURPOSE: An electrode assembly with minimized internal stress, and a secondary battery including thereof are provided to secure the low resistance and the high output powder of the electrode assembly. CONSTITUTION: An electrode assembly(110) includes a first electrode(112), a second electrode(113), and a separator(114) located in between the first and second electrodes. The first and second electrodes and the separator are winded into a jelly-roll shape. The first electrode includes at least two uncoated units separated formed from each other, and first tabs(135a,135b) and a second tab(136b) protruded from one side of the jelly roll and attached to the first uncoated unit. |
