Beschreibung
Zusammenfassung:	Disclosed is a method for manufacturing an electrode assembly, including at least one step selected from: a step of passing heat treated first separator and electrodes through a pair of surface-patterned rollers under pressurization to prepare a preliminary electrode assembly including the first separator laminated with the electrodes; and a step of passing a second separator on which the preliminary electrode assemblies are disposed through a pair of surface-patterned rollers under pressurization, and then carrying out winding in such a manner that the second separator may be interposed between the preliminary electrode assemblies. An electrochemical device including the electrode assembly is also disclosed.
