摘要： The present invention describes a component for a secondary battery and a manufacturing method thereof, and a secondary battery manufactured by using the component. The component for a secondary battery according to the present invention comprises a lead-free soldering bridge having a melting point of 150 to 300 °C and containing tin (Sn) and copper (Cu) as a main ingredient; the first and second metal plates spaced therebetween through a gap and coupling with the lead-free soldering bridge.
According to the present invention, when an over-current flows through the component for a secondary battery, the temperature of the lead-free soldering bridge is locally increased rapidly to melt the lead-free soldering bridge, thereby efficiently interrupting the flow of an over-current.

摘要： The present disclosure relates to a secondary battery having improved safety. The present disclosure provides a pouch type secondary battery which includes an electrode assembly and a pouch sheath material including a first pouch portion and a second pouch portion. The pouch-type secondary battery includes dual electrode leads wherein a first electrode lead is attached to the first pouch portion and a second electrode lead is attached to the second pouch portion. In the pouch-type secondary battery, electric current is interrupted by using a volumetric swelling phenomenon caused by swelling or pressure generated upon overcharge so that the battery may be prevented from being further charged. In addition, when pressure is increased by an additional reaction, venting occurs toward the inner lead portion of each of the dual electrode leads. As a result, it is possible to increase the stability of a battery cell, module and a pack received in the pouch, and thus to improve the life of a battery.
