ELECTRODE ASSEMBLY, BATTERY COMPRISING SAME, AND METHOD FOR MANUFACTURING SAME

摘要

An electrode assembly, a battery including the same, and a method of manufacturing the battery. The electrode assembly includes an electric insulation layer comprising a base unit having a first main surface and a second main surface opposite to the first main surface; a first electrode formed on the first main surface of the electric insulation layer; a first lead electrically connected to the first electrode and extending out of the electric insulation layer; a second electrode formed on the second main surface of the electric insulation layer and having different polarity from that of the first electrode; a second lead electrically connected to the second electrode and extending in a direction opposite from the extending direction of the first lead; and a separator arranged on at least one of the first electrode and the second electrode, wherein the electric insulation layer comprises a first anti-leakage unit formed along at least a portion of edges of the first main surface of the base unit and a second anti-leakage unit formed along at least a portion of edges of the second main surface of the base unit, and wherein the electric insulation layer is wound at least once around a winding axis parallel to the extending directions of the first lead and the second lead.
