Abstract
The present disclosure provides a stack-folding typed electrode assembly including 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, to allow easy impregnation of an electrolyte solution, and reduce the volume compared to a traditional electrode assembly.
