Beschreibung
Zusammenfassung:	The present invention relates to a safety apparatus and a protection method of a secondary battery, which can prevent explosion and fire of the secondary battery using a rupture switch attached on the outside of the secondary battery if a swelling degree of the secondary battery reaches a predetermined value when the secondary battery is swelled due to abnormal usage such as overcharge, short-circuit, reverse-connection and heat-exposure of large-capacity lithium polymer battery.
