Title:
ENERGY CONVERSION FILM, ENERGY CONVERSION ELEMENT AND METHOD FOR PRODUCING ENERGY CONVERSION FILM
Document Type and Number:
WIPO Patent Application WO/2021/020427
Kind Code:
A1
Abstract:
The present invention suppresses deterioration over time in adhesion between an electrode and a porous resin film. An energy conversion film which is a porous resin film having at least one surface that satisfies formula (1) and formula (2) described below. (1) 0.8 ≤ S1/S0 ≤ 1.0 (2) 2.0 ≤ S0 (In the formulae, S0 represents the oxygen atom concentration (atm%) before cleaning treatment (A); and S1 represents the oxygen atom concentration (atm%) after cleaning treatment (A). The oxygen atom concentration is the ratio of the number of oxygen atoms to the total number of oxygen atoms, carbon atoms and nitrogen atoms as determined by X-ray photoelectron spectroscopy (XPS), namely (number of oxygen atoms)/((number of oxygen atoms) + (number of carbon atoms) + (number of nitrogen atoms)). Cleaning treatment (A) is a cleaning treatment by means of distilled water.)
