摘要： Positive and negative electrode plates are respectively joined to positive and negative electrode terminals through leads. At least one of the leads joined to the positive or negative electrode plate is made of a stack of first and second metal layers. The first metal layer has a resistance higher than that of the second metal layer. The second metal layer has a melting point lower than that of the first metal layer. When a short-circuit current flows in the secondary battery, current is concentrated in the second metal layer to cause a blowout of the second metal layer, and then, an increase in an heat generation amount due to an increase in a current density of a short-circuit current flowing in the first metal layer causes a blowout of the first metal layer, thereby causing a blowout of the lead to interrupt the short-circuit current.

摘要： A battery pack includes: a plurality of secondary batteries; a housing for containing the secondary batteries; and at least one heat insulating layer for separating the secondary batteries from one another. The at least one heat insulating layer includes a foam material capable of foaming at a first predetermined temperature of 110° C. or more and less than 200° C. When the foam material foams, gas bubbles are produced in the heat insulating layer, so that the thickness of the heat insulating layer increases. The battery pack thus has excellent safety, exhibiting a high heat insulation effect in the event of abnormal heat generation of the batteries.
