Abstract
An electrode assembly according to an embodiment of the present invention for achieving the above object includes: a first electrode formed in the form of a single sheet and repetitively in-folded and out-folded at a predetermined interval; a second electrode provided in plurality and respectively interposed in spaces formed by folding the first electrode; a separator formed in the form of a single sheet and interposed between the first electrode and the second electrode so as to be repetitively in-folded and out-folded at a predetermined interval together with the first electrode; and a cover part configured to cover at least portions of an area, on which the separator is out-folded and an exposed surface, which is exposed to the outside together with the second electrode.
Claims15
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;
- a plurality of second electrodes interposed in spaces formed by folding the first electrode;
- a separator formed 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
- a cover part covering exposed out-folded portions of the separator and exposed end portions of the plurality of second electrodes, the cover part being in the form of a single film, the cover part being adjacent to the exposed out-folded portions of the separator,
- wherein the cover part does not contact exposed out-folded portions of the first electrode, and
- wherein the cover part is located at a first side of the electrode assembly and not at a second side of the electrode assembly opposite from the first side.
A method for manufacturing an electrode assembly, the method comprising:
- stacking a separator in the form of a single sheet on a first surface of a first electrode in the form of a single sheet;
- seating a plurality of second electrodes on the separator, the plurality of second electrodes spaced a predetermined interval from each other on the separator so as to form an electrode stack;
- in-folding and out-folding the first electrode and the separator to fold the electrode stack;
- and
- covering exposed out-folded portions of the separator and exposed end portions of the plurality of second electrodes with a cover part that is in the form of a single film,
- wherein the cover part is adjacent to the exposed out-folded portions of the separator,
- wherein the cover part does not contact exposed out-folded portions of the first electrode, and
- wherein the cover part is located at a first side of the electrode assembly and not at a second side of the electrode assembly opposite from the first side.
