Zusammenfassung:A rechargeable battery includes an electrode assembly including first and second electrodes; a case accommodating the electrode assembly; a cap plate having a short-circuit opening; a first terminal coupled to the first electrode; a second terminal coupled to the second electrode; and a short-circuit member at the cap plate, corresponding to the short-circuit opening, and configured to deform to electrically couple the first and second electrodes; and a short-circuit protrusion at the second terminal and configured to contact the short-circuit member, wherein a surface roughness of the short-circuit protrusion is greater than that of the cap plate.
