<p>PURPOSE: A secondary battery is provided to simplify production process, to increase a coupling force of a first coupling terminal, a second coupling terminal, and a bus bar, and to improve electric reliability between secondary batteries, or a secondary battery and an external electronic element. CONSTITUTION: A battery terminal of a secondary battery comprises: a current collecting terminal with a body part connecting to an electrode assembly inside a case of the secondary battery; and a coupling terminal(123) electrically and mechanically connecting to the body part. The coupling terminal comprises a body hoe penetrating through the body part, a screw thread connecting the coupling terminal to another secondary battery or an external element, and an anti-rotation element. A secondary battery(100) comprises an electrode battery, a battery terminal electrically connecting to the electrode assembly, a case(140) accepting the electrode assembly, and a cap assembly(150) comprising a cap plate sealing the case.</p> |
