Abstract
A secondary battery includes an electrode assembly, a case and a tab film. The electrode assembly has first and second electrode tabs formed to protrude therefrom. The case accommodates the electrode assembly so that a portion of at least one of the first and second electrode tabs is exposed to an outside thereof, and has a sealing portion formed along an edge portion thereof. The tab film is formed to surround at least one of the first and second electrode tabs that come in contact with the sealing portion of the case. In the tab film, at least one region of the tab film is formed of a material having a melting point different from that of the other region. Accordingly, the explosion and fire of the secondary battery is prevented, thereby improving the safety of the secondary battery.
