Claim:
1. A rechargeable battery comprising: an electrode assembly comprising a first electrode and a second electrode; a case configured to receive the electrode assembly; a first current collecting member comprising 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 comprising 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, wherein 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, and wherein a melting point of the first fuse unit is M1, a melting point of the second fuse unit is M2, and a resistance of the first fuse unit is equal to M1/M2 multiplied by a resistance of the second fuse unit.
