Abstract: Provided is a stacked electrode assembly including: a lowermost electrode arranged on a lowermost portion of the stacked electrode assembly; an uppermost electrode arranged on an uppermost portion of the stacked electrode assembly; at least one unit stacked body arranged between the lowermost electrode and the uppermost electrode and including a positive electrode, a negative electrode, and a separator, the separator being arranged between the positive electrode and the negative electrode; and a separator arranged between the lowermost electrode and the at least one unit stacked body, and between the at least one unit stacked body and the uppermost electrode. A capacity and energy density of a lithium battery may be improved by employing an electrode including a mesh electrode current collector as the lowermost electrode or the uppermost electrode of the stacked electrode assembly.
