Rechargeable battery

A rechargeable battery, comprising:

• an electrode assembly including a first electrode having a first electrode uncoated region at a first end of the electrode assembly, a second electrode having a second electrode uncoated region at a second end of the electrode assembly opposite the first end, and a separator interposed between the first and second electrodes;
• a first current collecting plate and a second current collecting plate spaced apart from each other, the first and second current collecting plates being electrically connected to the first and second electrode uncoated regions, respectively;
• a case configured to receive the electrode assembly, the first current collecting plate, and the second current collecting plate;
• a cap plate configured to seal the case;
• a first electrode terminal and a second electrode terminal extending through the cap plate, the first and second electrode terminals being electrically connected to the first and second current collecting plates, respectively;
• a first retainer adjacent to the cap plate, the first retainer being coupled to a first region of each of the first and second current collecting plates;
• and
• a second retainer coupled to a second region of each of the first and second current collecting plates or to each of the first and second electrode uncoated regions, the second retainer being separated from the first retainer, and the second regions of the first and second current collecting plates being different from the first regions of the first and second current collecting plates,
• wherein the first retainer includes:
• a first receiving part and a second receiving part, each of the first and second receiving parts having a receiving hole, and the first region of each of the first and second current collecting plates being inserted into a respective receiving hole, each of the first and second receiving parts overlapping at least four different surfaces of a respective inserted first region of the first and second current collecting plates, and
• a first supporting part connecting tops of the first receiving part and the second receiving part, the first supporting part being a horizontal portion of the first retainer parallel to the cap plate, and
• wherein the second retainer includes:
• a first connection part and a second connection part, each of the first and second connection parts having coupling holes, and the second regions of each of the first and second current collecting plates being inserted into respective coupling holes, and
• a second supporting part connecting the first connection part and the second connection part, the second supporting part being parallel to the cap plate and overlapping a bottom of the electrode assembly.
