Gel Polymer Electrolyte And Lithium Secondary Battery Comprising Same

Abstract: The purpose of the present invention is to provide a gel polymer electrolyte, which has a great effect of suppressing the leakage of an organic solvent by confining the organic solvent in a three-dimensional polymer network and has oxidation stability, flame retardancy, and heat stability as well as excellent lithium ion conductivity. To attain the purpose, the present invention provides a gel polymer electrolyte comprising a crosslinked 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 acryl group of fluorinated polyether diacrylate.
