Abstract
The present invention relates to an electrode assembly, and more specifically to an electrode assembly for a polymer secondary battery cell, including a cell stack part defined by stacking at least one radical unit having a four-layered structure in which a first electrode, a first separator, a second electrode and a second separator are stacked in turn, wherein at least one of the first electrode and the second electrode has a size corresponding to 99.7% to 100% of a size of the first separator or the second separator and thus is aligned to be coincided with or close to an end of the first separator or the second separator.
