SECONDARY BATTERY

A secondary battery is provided in which a first electrode (negative electrode) terminal and a second electrode (positive electrode) terminal may be concurrently (e.g., simultaneously) implemented in a cap assembly. A secondary battery includes: a case including a beading part and a crimping part; an electrode assembly physically coupled to the case and including a first electrode plate and a second electrode plate, the first electrode plate being electrically connected to the case; a first insulating gasket between the beading part and the crimping part; a cap plate coupled between the beading part and the crimping part through the first insulating gasket; a second insulating gasket extending through and coupled to the cap plate; and a rivet terminal extending through and physically coupled to the second insulating gasket, wherein the rivet terminal is electrically connected to the second electrode plate of the electrode assembly.
