Abstract
The present invention relates to an electrode assembly and a method for manufacturing the same, and more particularly, to an electrode assembly which is capable of improving an alignment of a secondary battery, realizing a high-capacity battery, and simplifying manufacturing processes of the secondary battery, and a method for manufacturing the same. The electrode assembly includes an electrode stack in which a plurality of first electrodes spaced apart from each other are disposed between two separators and second electrodes attached to both outer surfaces of the electrode stack at alternate positions of a plurality of positions on which the first electrodes are disposed, wherein, in the electrode stack, an area between the first electrode and the adjacent first electrode is folded.
