NOVELTY - The secondary battery has a cap plate (130) coupled with the case which accommodates an electrode assembly. A terminal (141) is electrically connected to the electrode assembly and is extended through a terminal hole (131) of the cap plate. A safety component (160) is provided between the terminal and the cap plate. A hemisphere apex base is electrically connected to cap plate and the terminal. The apex top portion is contacted with the other side surface of the cap plate and the terminal to electrically connect together the cap plate and the terminal.    USE - Secondary battery of battery pack for use as power source for smart phone, digital camera, electric scooter and hybrid electric vehicles (HEV).    ADVANTAGE - Since terminal and uncoated portion are made of the same material such as copper, copper alloy, nickel and a nickel alloy, the terminal can be easily welded to the uncoated portion. As the first region of the insulating molding resin is closely contacted with the top and bottom surfaces of the cap plate, the coupling force between the cap plate and the terminal can be improved. Hence sealing efficiency of the case is improved. Since the case and the cap plate are arranged without reaching the corrosion potentials, the corrosion of the case and the cap plate can be prevented. As the safety component is positioned between the cap plate and terminal, the current flowing from the terminal to the cap plate can be prevented. The nail penetration or crush of the secondary battery can be prevented so as to improve the penetration safety of the secondary battery. As the first terminal portion and the second terminal portion are coupled by the insulating molding resin using an insert molding method, the assembling process of the secondary battery can be simplified. Hence the numbers of components of the first terminal portion and the second terminal portion is relatively small. The length of current path and current resistor can be reduced so as increase the size of electrode assembly by reducing volumes of terminal portions.
