Abstract

The present invention relates to a secondary battery, wherein an electrode tab of an electrode assembly and a pack tab for modularization are electrically connected by a cap-up without any other configuration, so as to reduce resistance and heat generation, which may occur on a current path. For this purpose, a secondary battery is disclosed, the secondary battery including: a cylindrical can having an upper end opening; an electrode assembly received in the cylindrical can and having an electrode tab; and a cap assembly for sealing the upper end opening of the cylindrical can. The cap assembly includes: a circular-plate-shaped safety plate having a bent which is broken when the pressure inside the cylindrical can increases; and a cap-up disposed on the upper portion of the safety plate and surrounding the edge portion of the safety plate, and the electrode tab is in contact with and coupled to the cap-up.
