Claim 13:
14. An electronic device comprising:
a housing defining an inner space;
a battery including an electrode assembly including:
a positive electrode including a positive electrode tab provided at one end,
a negative electrode disposed on one surface of the positive electrode and including a negative electrode tab provided at one end,
a first separator disposed between the positive electrode and the negative electrode to separate the positive electrode from the negative electrode and including an extension extending from another end of the positive electrode or the negative electrode, and
a second separator including one surface disposed on another surface of the positive electrode or the negative electrode, and
a pouch wrapping the electrode assembly, the battery being disposed in the inner space; and

a bracket on which the battery is seated,
wherein the positive electrode, the negative electrode, the first separator, and the second separator are wound so that the extension of the first separator is in contact with an inner surface of the pouch, and the first separator is fixed to the pouch by an adhesive layer provided on an exposed surface of the extension,
wherein the first separator includes a base film and a binder disposed on both surfaces of the base film, and
wherein the base film and the binder are wound such that the adhesive layer is attached to a terminal end of the binder at an interior of the electrode assembly, and terminates after winding to form an exterior surface of the electrode assembly.
