Claim Text:
1. A stacking or stacking/folding type electrode assembly comprising: a plurality of metal foils having electrode tabs; an electrode lead coupled and being electrically connected to the electrode tabs, the electrode lead being formed in the shape of a straight line in vertical section; wherein the electrode assembly is constructed in a structure in which the electrode tabs, having no active material applied thereto, protrude from the plurality of metal foils; and wherein the electrode tabs are joined to the top and the bottom of the electrode lead at an electrode lead-electrode tabs joint portion and the average resistance difference between the electrode tabs is less than 0.05 milliohms; and wherein the number of the electrode tabs joined to the top of the electrode lead is approximately equal to that of the electrode tabs joined to the bottom of the electrode lead; wherein the electrode tabs include bending sections and coupling sections, the bending sections being angled in one direction between 0 and 90 degrees with respect to the electrode lead.
