Claim 16:
17. A stacked electrode assembly, comprising;
a first electrode at a first portion of the stacked electrode assembly;
a second electrode at a second portion of the stacked electrode assembly;
a unit stacked body between the first electrode and the second electrode;
a first separator between the first electrode and the unit stacked body; and
a second separator between the unit stacked body and the second electrode, wherein:
the unit stacked body includes a first positive electrode, a first negative electrode, and a third separator, the third separator being between the first positive electrode and the first negative electrode,
the first electrode includes a first mesh electrode current collector and a second mesh electrode current collector, the first mesh electrode current collector being spaced apart from the second mesh electrode current collector in a thickness direction of the first electrode,
the first electrode includes a third mesh electrode current collector, which is spaced apart from each of the first mesh electrode current collector and the second mesh electrode current collector in the thickness direction of the first electrode,
the first mesh electrode current collector is interposed between the second mesh electrode current collector and the third mesh electrode current collector, and
the second and third mesh electrode current collectors have openings at different locations or have different aperture ratios from the first mesh electrode current collector.
