Rechargeable battery having fuse unit |
摘要 |
A rechargeable battery includes: an electrode assembly including first and second electrodes; a case containing the electrode assembly; a cap plate covering an opening of the case; a first terminal protruding outside of the case and electrically coupled to the first electrode; a second terminal protruding outside of the case and electrically coupled to the second electrode; a current collector including first and second fuse units, and electrically coupled to the first electrode, wherein the first fuse unit and the second fuse unit each have a cross-sectional area smaller than a cross-sectional area of an adjacent region and are spaced from each other; and a connector coupled to the current collector between the first fuse unit and the second fuse unit, and adapted to electrically couple the cap plate and the current collector, wherein a resistance of the connector is less than that of the first terminal. |
