摘要： An electrode assembly includes at least one first unit cell obtained by stacking a first electrode, a separator, a second electrode, a separator and a first electrode one by one, and at least one second unit cell obtained by stacking a second electrode, a separator, a first electrode, a separator and a second electrode one by one. The first unit cell and the second unit cell are alternately and repeatedly disposed between a separator sheet folded in zigzags.

摘要： An electrode assembly includes a cell stack part having (a) a structure in which one kind of radical unit is repeatedly disposed, or (b) a structure in which at least two kinds of radical units are disposed in a predetermined order. The one kind of radical unit has a four-layered structure in which first electrode, first separator, second electrode and second separator are sequentially stacked or a repeating structure in which the four-layered structure is repeatedly stacked. Each of the at least two kinds of radical units are stacked by ones to form the four-layered structure or the repeating structure. The separator has a larger size than the electrode to expose an edge part of the separator to outside of the electrode and the separator. The edge parts of the separators included in one radical unit or in the cell stack part are attached to form a sealing part.

摘要： An electrode assembly includes a cell stack part having (a) a structure in which one kind of radical unit is repeatedly disposed, or (b) a structure in which at least two kinds of radical units are disposed in a predetermined order, the one kind or the at least two kinds of radical units having same number of electrodes and separators alternately disposed. The one kind of radical unit has four-layered structure in which first electrode, first separator, second electrode and second separator are sequentially stacked or repeating structure of the four-layered structure. Each of the at least two kinds of radical units are stacked by ones to form the four-layered structure or the repeating structure. An outer separator that is a separator among separators of a radical unit positioned at the outermost part of the cell stack part is extended from a side of the cell stack part.
