Rechargeable battery

A rechargeable battery comprising:

• a case;
• an electrode assembly housed in the case and comprising a first electrode, a second electrode, and a separator between the first electrode and the second electrode, the first electrode having a coated portion coated with a first active material and an uncoated portion absent the first active material;
• a cap assembly physically coupled to the case and comprising a terminal electrically coupled to the electrode assembly;
• a safety assembly housed in the case, the safety assembly comprising a first electric conductive plate of a first electrical polarity, a first supporting protrusion extending from the first electric conductive plate and physically coupled to the uncoated portion, and a second electric conductive plate of a second electrical polarity different from the first electrical polarity the first electric conductive plate and the second electric conductive plate both being on only a single side of the electrode assembly;
• a current collecting tab electrically coupling the electrode assembly with the terminal and physically coupled to the uncoated portion;
• and
• a first auxiliary plate physically coupled to the uncoated portion at a surface of the uncoated portion opposite to where the first supporting protrusion is physically coupled to the uncoated portion.
