The present invention relates to an electrode assembly and, more specifically, to an electrode assembly comprising a plurality of unit cells and a separation film which continuously winds the unit cells. In the electrode assembly of the present invention, the first unit cell to an n^th unit cell are sequentially wound so that an (n-1)^th unit cell and the n^th unit cell can be placed on the outermost perimeter of the electrode assembly, and a first unit cell is positioned at the central portion of the electrode assembly with respect to a lamination direction of the unit cells while n unit cells are disposed on the separation film which is longer than the width. On one side or both sides of a unit cell lamination structure, one to six unit cells, sequentially from the outermost unit cell, comprise: a positive electrode which is composed of a relatively reduced amount of a conductive material than the unit cells positioned therein other than the one to six unit cells or does not comprise the conductive material at all, or the positive electrode and a negative electrode. The present invention further relates to a lithium secondary battery comprising the same. |
