Abstract
The present application discloses a secondary battery, a battery module, and a device using the secondary battery as a power source. The secondary battery includes: a casing; an electrode assembly disposed in the casing; a cap assembly; and a current collecting member including an adapting piece and a connecting component provided separately and connected with each other; the adapting piece connected with the electrode terminal of the cap assembly and including a guiding section; the connecting component including a current collecting section to be connected with the guiding section and a tab connecting section to be connected with the electrode assembly; and the connecting component has a rigidity less than that of the guiding section, so that deformation of the guiding section toward the electrode assembly can be reduced when a portion of the connecting component connected with the electrode assembly is bent with respect to the length direction.
