Document Type and Number:
Japanese Patent JP6950857
Kind Code:
B2
Abstract:
Provided is an adhesive film for metal terminals that exhibits high adhesion strength to a metal terminal even when the heating temperature during bonding of the adhesive film for metal terminals to the metal terminal is a low temperature of 140 to 180°C, for example. An adhesive film for metal terminals, which is to be interposed between a metal terminal electrically connected to an electrode of a power storage device element and a power storage device packaging material for sealing the power storage device element, wherein a value of the following tensile elastic modulus A after heating is smaller than a value of the following tensile elastic modulus B before heating:tensile elastic modulus A after heating: a tensile elastic modulus as measured in an environment at a temperature of 25°C, after the adhesive film for metal terminals is allowed to stand in a heating environment at a temperature of 140°C for 12 seconds, and then in an environment at a temperature of 25°C for 1 hour;tensile elastic modulus B before heating: a tensile elastic modulus as measured in an environment at a temperature of 25°C.
