ELECTRODE ASSEMBLY AND METHOD OF MANUFACTURING THE SAME

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

主权项

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