1. A rechargeable battery, comprising:
- at least one electrode assembly that performs charging and discharging;
a case receiving the electrode assembly;
a cap assembly coupled to the case and including at least one terminal electrically connected to the electrode assembly;
a lead tab electrically connecting the terminal and the electrode assembly; and
a supporting member between the lead tab and the case,wherein;
the lead tab includes at least one coupling bar attached to the electrode assembly,the supporting member includes a supporting protrusion coupled to one surface of the coupling bar and a base supported by an inner surface of the case,the coupling bar includes a welding portion welded to an uncoated region of the electrode assembly,the coupling bar includes a protruding hook portion, the hook portion being bent to protrude obliquely with respect to a plane of the welding portion,the coupling bar includes an insertion tip on the hook portion such that the hook portion is between the insertion tip and the welding portion, the insertion tip being separated from the uncoated region of the electrode assembly and being parallel with the welding portion,the at least one electrode assembly includes a plurality of electrode assemblies, andthe insertion tip of the coupling bar extends between adjacent uncoated regions of the plurality of electrode assemblies.
