COMPLEX ELECTRODE ASSEMBLY INCLUDING PLURALITY OF ELECTRODE ASSEMBLIES AND ELECTROCHEMICAL DEVICE COMPRISING THE COMPLEX ELECTRODE ASSEMBLY

摘要

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.

1. A complex electrode assembly comprising:
a first sheet-type wiring which extends in a lengthwise direction thereof and comprises a sheet region, a width of which in a direction perpendicular to the lengthwise direction is greater than a thickness thereof in a direction perpendicular to the lengthwise direction and a width direction of the first sheet-type wiring; and a plurality of electrode assemblies which are arranged to be spaced apart from each other in the lengthwise direction of the first sheet-type wiring and are electrically connected to the first sheet-type wiring, wherein each of the electrode assemblies comprises a first electrode tab electrically connected to the first sheet-type wiring, wherein outer surfaces of each of the electrode assemblies comprises a first outer surface and a second outer surface arranged opposite to each other in the lengthwise direction of the first sheet-type wiring, a third outer surface and a fourth outer surface arranged opposite to each other in the width direction of the first sheet-type wiring, and a fifth outer surface and a sixth outer surface arranged opposite to each other in a thickness direction of the first sheet-type wiring, the first sheet-type wiring is disposed to face the fifth or sixth outer surface of at least one of the electrode assemblies, and the first electrode tab is partially bent in a way such that a portion of the first electrode tab is bonded with the first sheet-type wiring.
