The present invention relates to a jelly-roll type electrode assembly. Provided is the jelly-roll type electrode assembly containing a structure of cathode/separation membrane/anode, wherein each electrode is coated with an active material coating layer on one surface or both surfaces of a sheet-type current collector, the active material layer comprises a first active material layer and a second active material layer having different loading amounts, and a loading amount of the second active material layer is lower than that of the first active material layer. |
