Secondary battery

A secondary battery comprising:

• an electrode assembly comprising a first electrode plate, a second electrode plate, and a separator between the first electrode plate and the second electrode plate;
• a case accommodating the electrode assembly and comprising a top opening;
• a cap plate sealing the top opening of the case and comprising a short-circuit hole;
• a first electrode terminal electrically coupled to the first electrode plate and protruding to an upper portion of the cap plate;
• an inductive element electrically coupled to the first electrode terminal and having self-inductance;
• a first connection plate electrically coupled to the inductive element and separated from the cap plate;
• and
• an inversion plate in the short-circuit hole,
• wherein the inductive element couples the first electrode terminal and the first connection plate to each other and comprises a plurality of conductive plates forming a coil shape.
