Abstract

A wrapping electrode assembly for use in a secondary battery manufactured by an electrode-stacking method includes: an electrode plate which has a coating layer of an electrode active material and a non-coated protruding portion, the electrode active material being capable of reversibly inserting and extracting lithium ions; first and second separator films which cover both surfaces of the electrode plate while exposing only the non-coated protruding portion; and an insulating polymer film which is positioned between the first separator film and the second separator film at least on a portion of a circumference of the electrode plate to be bonded to the first separator film and the second separator film, wherein the insulating polymer film is formed as being divided into at least two parts.
