PURPOSE: A secondary battery is provided to be formed in order to combine the current collection terminal and coupling terminal with a terminal plate, thereby increasing coupling force of a bus bar and an electrode terminal. CONSTITUTION: A secondary battery comprises an electrode assembly(110), a case(140) in which the electrode assembly is put, a cap assembly(150) in which a cap plate(151) which seals a top opening of the case, and electrode terminals(120,130) which are electrically connected to the electrode assembly and are projected to outside of terminal holes. The electrode terminal comprises current collecting terminals(125,135) which passes through the terminal holes of the cap plate, terminal plates(123,133) which is combined to the current collection terminal, and coupling terminals(121,131) which is combined to the terminal plate. A short circuit hole is formed in the cap-plate which is corresponding to the coupling terminal. |
