Abstract
Disclosed is a jellyroll-type electrode assembly including a first electrode, a second electrode, and a separator interposed between the electrodes folded together, in which the first electrode has a non-coating part and a first electrode tab attached onto the non-coating part, the non-coating part representing a part of the first electrode not coated with an active material, and the at least double-folded-layer separator is disposed between the first electrode tab and the second electrode.
