Gel polymer electrolyte separator, and preparation method and use thereof

Abstract

Provided are a gel polymer electrolyte separator, and a preparation method and use thereof. The gel polymer electrolyte separator is prepared from raw materials including a masterbatch and an extractant, where the masterbatch includes the following components in mass percentage, based on a mass of the gel polymer electrolyte: 53% to 81% of an organic solvent, 10% to 21% of a polymer substrate, 6% to 19% of a pore-forming agent, and 1% to 8% of a nano-functional material; the polymer substrate is one or two selected from the group consisting of a polyvinylidene fluoride (PVDF) homopolymer and a PVDF-hexafluoropropylene (HFP) copolymer; and the nano-functional material is one or more selected from the group consisting of Al2O3, SiO2, TiO2, LLZO, LLZTO, LLTO, NASICON, LAGP, and LATP.
