RECHARGEABLE BATTERY HAVING FUSE UNIT

摘要

A rechargeable battery includes: an electrode assembly including a first electrode and a second electrode, a case configured to receive the electrode assembly, a first current collecting member including a first fuse unit coupled to the first electrode and having a cross-sectional area that is smaller than a cross-sectional area of a periphery of the first current collecting member, and a second current collecting member including a second fuse unit coupled to the second electrode and having a cross-sectional area that is smaller than a cross-sectional area of a periphery of the second current collecting member, in which the first fuse unit is configured to melt more quickly than the second fuse unit at a first current, and the second fuse unit is configured to melt more quickly than the first fuse unit at a second current that is lower than the first current.
