US 2024/0176200 A1 · GEL ELECTROLYTE AND ELECTROCHROMIC ELEMENT

Abstract

A gel electrolyte includes a cured product of an electrolyte composition containing a binder resin and a supporting electrolyte. The gel electrolyte has a peeling index of 5.5 mm−1 or greater but 7.5 mm−1 or less. The peeling index is obtained by dividing a maximum stress by an integral value obtained by integrating stress based on peeling distance, where the stress, peeling distance, and maximum stress are measured by probe tack test performed at environmental condition of 25° C. by bringing stainless steel probe having diameter of 5 mm into contact with the gel electrolyte having average thickness of 700 micrometers from above the gel electrolyte at a speed of 120 mm/second, keeping the stainless steel probe under pressing load of 40 gf for a pressing load retention time of 5 seconds, and peeling the stainless steel probe in perpendicular direction at speed of 400 mm/second.
