Claim 2:
3. An electrode assembly, comprising:
a first electrode in the form of a single sheet that is repetitively in-folded and out-folded at a predetermined interval, the first electrode being a single-sided electrode in which a first electrode active material is applied to only a first surface of a first electrode collector and not to a second surface of the electrode collector opposite to the first surface;
a plurality of second electrodes interposed in spaces formed by in-folding the first electrode, each of the plurality of second electrodes being interposed only in a corresponding one of the spaces formed by in-folding the first electrode;
a separator in the form of a single sheet that is interposed between the first electrode and the plurality of second electrodes so as to be repetitively in-folded and out-folded at the predetermined interval together with the first electrode; and
an insulating part in the form of a single film disposed on the second surface of the first electrode collector, the insulating part having adjacent confronting portions that are in surface contact with one another wherein the second surface of the first electrode collector has adjacent confronting portions that face one another with only the insulating part therebetween.
