Title:
ADHESIVE FILM FOR METAL TERMINALS, METAL TERMINAL WITH ADHESIVE FILM FOR METAL TERMINALS, ELECTRICITY STORAGE DEVICE USING SAID ADHESIVE FILM FOR METAL TERMINALS, AND METHOD FOR PRODUCING ELECTRICITY STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/006351
Kind Code:
A1
Abstract:
The present invention provides an adhesive film for metal terminals, said adhesive film exhibiting high adhesion strength to a metal terminal even if the heating temperature during bonding to the metal terminal is low, for example a low temperature from 140°C to 180°C. An adhesive film for metal terminals to be interposed between a metal terminal that is electrically connected to an electrode of an electricity storage device element and an outer covering material for electricity storage devices, said outer covering material sealing the electricity storage device element, wherein the value of the tensile elastic modulus A after heating described below is smaller than the value of the tensile elastic modulus B before heating described below. Tensile elastic modulus A after heating: The tensile elastic modulus as measured in an environment at 25°C after leaving the adhesive film at rest for 12 seconds in a heating environment at 140°C and subsequently leaving the adhesive film at rest for one hour in an environment at 25°C. Tensile elastic modulus B before heating: The tensile elastic modulus as measured in an environment at 25°C.
