Title:
METAL TERMINAL ADHESIVE FILM, METAL TERMINAL ADHESIVE FILM-ATTACHED METAL TERMINAL, BATTERY USING SAID METAL TERMINAL ADHESIVE FILM, AND BATTERY MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/021997
Kind Code:
A1
Abstract:
A metal terminal adhesive film which is interposed between a metal terminal connected to an electrode of a battery element and a packaging material for sealing the battery element is provided with a first polyolefin layer, a base material film comprising a stretched film including polyethylene naphthalate, and a second polyolefin layer in this order. At least one of the first and the second polyolefin layers includes acid-denatured polyolefin. When infrared absorption spectra are acquired with respect to a surface of the base material film by polarization measurement using a single-reflection ATR method of Fourier transform infrared spectroscopy in a direction perpendicular to a thickness direction and in 18 directions at 10° intervals from an arbitrary reference direction of 0° to 170°, a value obtained by calculating, in each direction, a value Y by dividing an absorption peak intensity Y765 of the infrared absorption spectra at 765 cm-1 by an absorption peak intensity Y1181 at 1181 cm-1, and then by dividing a maximum value Ymax of the values Y by a minimum value Ymin is not less than 1.0 and not more than 1.3.
