A rechargeable battery comprising:
- an electrode assembly comprising electrodes having coated and uncoated regions and being located at opposite sides of a separator;
- a case accommodating the electrode assembly;
- a cap plate sealing the case and having terminal holes through which electrode terminals coupled to the uncoated regions extend;
- a gasket between each electrode terminal and the cap plate;
- and
- a first insulating plate between the cap plate and the electrode assembly and fastened to the gaskets, wherein the uncoated regions and the electrode terminals are coupled by lead tabs located on the first insulating plate facing the cap plate, and wherein the uncoated regions pass through receiving grooves on the first insulating plate and are coupled to the lead tabs.
