Stack-folding type electrode assembly

A stack-folding typed electrode assembly, comprising:

• an electrode assembly having a structure in which a plurality of unit cells overlaps and a continuous folding separator is interposed between each overlapping part,
• wherein the continuous folding separator comprises a continuous porous polymer substrate having pores;
• and an organic-inorganic porous coating layer formed of a mixture of inorganic particles and a binder polymer,
• wherein the organic-inorganic porous coating layer is discontinuously provided at the overlapping part, such that the organic-inorganic porous coating layer has a plurality of discontinuous portions, adjacent ones of the discontinuous portions being spaced apart from one another by gradually increasing intervals in a folding direction of the continuous folding separator.
