NOVELTY - The battery has a case for housing an electrode assembly. An electrode connection assembly is electrically coupled to the electrode assembly and provided with a terminal (331). A current collector (334) is electrically coupled to the electrode assembly. An insulating element (333) is arranged between the terminal and the collector. A portion of the insulating element is spaced from the terminal and the collector. A connection element (335) is coupled to the terminal and the collector, and comprises a fuse part (335d). The portion of the insulating element overlaps with the connection element.    USE - Rechargeable battery e.g. low-capacity rechargeable battery for a small electronic device such as mobile phone, laptop computer and camcorder, and large-capacity rechargeable battery for use as a power supply for driving a motor of a hybrid vehicle and an electric car. Can also be used for lithium polymer battery or cylindrical battery.    ADVANTAGE - The electrode assembly is moved even if external impact is applied to the rechargeable battery so as to prevent the electrode assembly from being damaged by configurations installed to a molding part between cap plates. The battery can absorb arc or heat generated when the fuse part of the connection element is fractured, to another portion of the insulating element positioned between a first coupling part and a second coupling part, so that an electrode of the rechargeable battery can be prevented from being damaged by fracturing of the fuse part. The battery avoids abnormal operation of the fuse part that is fractured at temperature higher or lower than predetermined temperature. The battery ensures that a supporting protrusion of the insulating element inserted into a fuse hole of the fuse part absorbs the arc or heat generated between broken surfaces after the fuse part is fractured so as to prevent the arc or heat from being moved outside an insulating layer, so that the rechargeable battery can be prevented from being damaged. The connection element is positioned between a coating region coated with active material of the electrode assembly and the cap plate, so that an electrode uncoated region is prevented from being damaged by the arc or heat generated when the fuse part of the connection element is fractured.
