Abstract
Disclosed herein is a stacking or stacking/folding type electrode assembly of a cathode/separator/anode structure, wherein the electrode assembly is constructed in a structure in which tabs (electrode tabs), having no active material applied thereto, protrude from electrode plates constituting the electrode assembly, electrode leads are located at one-side ends of the stacked electrode tabs such that the electrode leads are electrically connected to the electrode tabs, and protruding lengths of the electrode tabs are gradually increased according to the distances between the electrode leads and the electrode tabs, whereby the lengths of the electrode tabs at joint portions between the electrode tabs and the electrode leads are the same. Also disclosed is an electrochemical cell including the electrode assembly.
