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.

Electrode assembly and lithium battery comprising same

A secondary battery including an electrode assembly; a first case that includes an electrode assembly accommodating space; and a second case that coupled to the first case, the second case facing the first case and having a convex-concave pattern.

Secondary battery

A stack-type electrode assembly includes a lowermost electrode in a lowermost portion of the electrode assembly; an uppermost electrode in an uppermost portion of the electrode assembly; at least one unit stack between the lowermost electrode and the uppermost electrode, the at least one unit stack comprising a positive electrode, a negative electrode, and a separator disposed between the positive electrode and the negative electrode; and a plurality of separators between the lowermost electrode and unit stack, between the unit stacks, and between the unit stack and the uppermost electrode.
