Provided is a secondary battery comprising a core (7), tabs (4) protruded from an end of the core (7), a tab lead-out device placed at the end of the core (7), and a cover plate (1). The tab lead-out device includes an insulating layer (6) adjacent to the end of the core (7) and a conductive layer (5) distant from the end of the core (7). The tabs (4) are electrically connected to the conductive layer (5). The conductive layer (5) is electrically connected to the cover plate (1). The secondary battery further comprises a connector and a pad (3) stacked between the conductive layer (5) of the tab lead-out device and the cover plate (1). The tabs (4) are compacted between the pad (3) and the conductive layer (5) of the tab lead-out device by the connector. |
