A complex electrode assembly includes a first sheet-type wiring which extends in a lengthwise direction of the first sheet-type wiring and comprises a sheet region of which a width that is perpendicular to the lengthwise direction is greater than a thickness that is perpendicular to the lengthwise direction and a width direction of the first sheet-type wiring, and electrode assemblies which are arranged separate from each other in the lengthwise direction of the first sheet-type wiring and are electrically connected to the first sheet-type wiring. The first sheet-type wiring may be disposed to face an outer surface of each of the electrode assemblies.

Complex electrode assembly including plurality of electrode assemblies and electrochemical device comprising the complex electrode assembly

An electrode assembly includes an electrode jelly-roll, which includes a winding including a first electrode plate, a second electrode plate, and a separator disposed between the first and second electrode plates; an outer surface parallel to a winding axis of the prismatic electrode jelly-roll, side surfaces perpendicular to the winding axis; a first electrode tab, which is electrically connected to the first electrode plate and extends in a winding axis direction of the prismatic electrode jelly-roll; a second electrode tab, which is electrically connected to the second electrode plate and extends in a winding axis direction of the electrode jelly-roll, wherein an end portion of at least one of the first electrode tab and the second electrode tab is bent in a direction opposite to the direction in which the corresponding electrode tab extends and faces an outer surface of the prismatic electrode jelly-roll.
