摘要： An exemplary embodiment of the present invention provides a rechargeable battery that can block a current of a cell without causing quality scatter by removing operating scatter of the overcharge safety device upon occurrence of overcharge in the cell.
An overcharge safety device according to an exemplary embodiment of the present invention includes: an electrode assembly in which a first electrode and a second electrode are disposed at opposite sides of a separator; a case in which the electrode assembly is accommodated; a cap plate that is combined to an opening of the case; a first electrode terminal and a second electrode terminal that are provided in terminal holes of the cap plate and respectively connected to the first electrode and the second electrode; and an overcharge safety device in which a first free end and a second free end of a first short-circuit member and a second short-circuit member that are respectively connected to the first electrode terminal and the second electrode terminal in the cap plane are disposed apart from each other and received in a tube.
