Abstract: Disclosed herein is a secondary battery including two or more stacking-folding type cells (‘unit cells’) manufactured by winding small-sized electrode assemblies (‘bicells’) constructed in a stacking type structure in which electrodes having the same polarity are located at opposite sides of each electrode assembly and small sized electrode assemblies (‘full cells’) constructed in a stacking type structure in which electrodes having different polarities are located at opposite sides of each electrode assembly using a long separator sheet, wherein the unit cells are mounted in a battery case, each unit cell has one or more electrode terminals protruding from each end of each unit cell, and the unit cells are mounted in a receiving part of the battery case such that the unit cells are arranged in a stacking arrangement structure or a plane arrangement structure while the electrode terminals of the unit cells are connected with each other.

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, 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.
