Zusammenfassung:	A secondary battery including an electrode assembly having a positive electrode plate, a negative electrode plate and a separator being wound together, a can for receiving the electrode assembly; the can having an opening. A cap assembly includes a cap plate having an electrolyte injection hole, the cap assembly sealing the opening of the can. A lead plate is welded to an exterior-facing surface of the cap plate so as to cover the electrolyte injection hole and a protection circuit board is electrically coupled to the cap assembly. At least one positioning member is located to be aligned with at least one edge of the lead plate, the at least one positioning member defining a region for receiving the lead plate.
