ELECTRODE ASSEMBLY HAVING TAB-LEAD JOINT PORTION OF MINIMIZED RESISTANCE DIFFERENCE BETWEEN ELECTRODES AND ELECTROCHEMICAL CELL CONTAINING THE SAME

摘要

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, the electrode tabs are electrically connected to an electrode lead, and the pluralities of electrode tabs are joined to the top and the bottom of the electrode lead at an electrode lead-electrode tabs joint portion such that the resistance difference between electrodes at the electrode lead- electrode tabs joint portion is minimized. Also disclosed is an electrochemical cell including the electrode assembly.
