Gel polymer electrolyte and lithium secondary battery including the same

Abstract

The present disclosure aims at providing a gel polymer electrolyte which has a great effect of inhibiting leakage of an organic solvent by confining the organic solvent in a three-dimensional polymer network and has oxidation stability, flame retardancy, thermal stability, and excellent lithium ion conductivity. In order to achieve the above object, the present disclosure provides a gel polymer electrolyte including a cross-linked polymer having a thiol-ene structure, wherein the thiol-ene structure is formed by a click reaction of a thiol group of a thiol compound containing at least four reactive thiol groups per molecule and an acrylic group of a fluorinated polyether diacrylate.
