Abstract

Disclosed herein is an electrode assembly including two or more electrode plates, each of which has electrode tabs, and a separator plate disposed between the electrode plates and/or a one-unit separation sheet disposed between the electrode plates to cover side surfaces of the electrode plates, which constitute an electrode tab non-formation region, wherein the electrode plates are stacked in a height direction on the basis of a plane such that the electrode plates having opposite polarities face each other in a state in which the separator plate and/or the separation sheet is disposed between the electrode plates, a stack constituted by the electrode plates includes electrode plates having different sizes, and an absolute value of the difference in thickness between the electrode plates having different sizes facing each other is 0 to 79 μm.
