Abstract
This adhesive film for a metal terminal is interposed between a metal terminal electrically connected to an electrode of a battery element and a wrapping material sealing the battery element and is provided with at least one resin layer having a polyolefin backbone. When the adhesive film for the metal terminal is measured with a differential scanning calorimeter, a melting peak is observed within the range of 120° C. to 156° C.
Claims17
