摘要： 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.
