1. A battery comprising:
an electrode assembly including a first electrode, a second electrode, and a separator between the first electrode and second electrode, wherein the first electrode, the second electrode, and the separator are wound about an axis, wherein the first electrode has a pair of first sides and a pair of second sides extending between the pair of first sides, a first portion including an active material extending between the pair of first sides, and a second portion extending between the pair of first sides and exposed beyond the separator, wherein at least a part of the second portion includes an electrode tab;
a battery housing having a first end with a first opening, a second end with a second opening opposite the first end, and an inner surface, the battery housing accommodating the electrode assembly through the first opening formed at the first end;
a first current collector comprising a tab coupling portion coupled to the second portion of the first electrode and a housing coupling portion extending from the tab coupling portion and electrically coupled to the inner surface of the battery housing; and
a cap covering the first opening of the battery housing, the cap being separate from the first current collector,
wherein the first current collector is located between the electrode assembly and the cap,
wherein the second portion of the first electrode is connected to an inner surface of the first current collector so as to not extend through the first current collector,
wherein the battery housing comprises a beading portion formed on an end portion adjacent to the first opening at the first end and press-fitted inward, and
wherein the housing coupling portion comprises:
a contact portion coupled to the beading portion of the battery housing; and
a connecting portion to connect the tab coupling portion to the contact portion.
