Secondary battery

A secondary battery, comprising:

• an electrode assembly including a first electrode plate, a second electrode plate, and a separator between the first and second electrode plates, the electrode assembly being wound around a winding axis;
• a wrapping tape including a first surface facing the electrode assembly and a second surface opposite to the first surface, the wrapping tape including a first end and a second end, the wrapping tape being wound around the winding axis of the electrode assembly to completely surround the electrode assembly such that the first end and the second end meet each other when the wrapping tape is wound, and the wrapping tape having adhesive layers coated only on parts of the first surface such that other parts of the first surface of the wrapping tape do not have adhesive layers coated thereon, wherein the adhesive layers include a first adhesive layer on the first surface of the wrapping tape at the first end of the wrapping tape, a second adhesive layer on the first surface of the wrapping tape at the second end of the wrapping tape, and a third adhesive layer on the first surface of the wrapping tape between the first adhesive layer at the first end of the wrapping tape and the second adhesive layer on the first surface of the wrapping tape at the second end of the wrapping tape, wherein a portion of the other parts of the first surface of the wrapping tape that do not have adhesive layers coated thereon directly contact the electrode assembly;
• a can including an opening at a side thereof to insert the electrode assembly therethrough, the can accommodating the electrode assembly therein;
• and
• a cap assembly configured to close the opening of the can.
