Abstract
A method of manufacturing an electrode assembly includes a first step of forming one kind of a radical unit or at least two kinds of radical units having an alternately stacked structure of a same number of electrodes and separators; and a second step of forming a cell stack part by repeatedly stacking one kind of the radical units, or by stacking at least two kinds of the radical units. Edge of the separator is not joined with that of adjacent separator. One kind of radical unit has a four-layered structure in which first electrode, first separator, second electrode and second separator are sequentially stacked together or a repeating structure in which the four-layered structure is repeatedly stacked, and at least two kinds of radical units are stacked by ones to form the four-layered structure or the repeating structure.
