摘要： A secondary battery having an improved current-collecting structure is provided. In an example embodiment, the secondary battery includes an electrode assembly including a plurality of unit electrode plates each including a pair of non-coating portion tabs at a first side and a plurality of separators each located between the unit electrode plates; and a current collector plate welded to the non-coating portion tabs, and the current collector plate is welded in a state in which the pair of non-coating portion tabs are bent in opposite directions. The pair of non-coating portion tabs are bent in opposite directions to then be welded to the current collector plate, and welding may be complementarily performed, thereby securing electrical stability.

摘要： A secondary battery has a simplified structure of a terminal part to reduce the number of parts, and terminal parts can be directly connected without requiring a separate part (for example, a bus bar) for mutual electrical connection between a battery and another battery. A secondary battery comprises: an electrode assembly, a case for accommodating the electrode assembly; a cap plate coupled to the case; and a terminal part that is electrically connected to the electrode assembly and is extended to penetrate through the cap plate, wherein the terminal part comprises a first area having a first thickness that is electrically connected to the electrode assembly from the inside of the case, and a second area having a second thickness that is thicker than the first thickness and is electrically connected to the first area from the outer side of the case.
