GEL POLYMER ELECTROLYTE, METHOD FOR MANUFACTURING THE SAME, AND ELECTROCHEMICAL DEVICE INCLUDING THE SAME

摘要

The present invention relates to a gel polymer electrolyte, a method for manufacturing the same, and an electrochemical device including the same. The present invention provides the gel polymer electrolyte, the method for manufacturing the same by thermal cross-linking or optical cross-linking, and the electrochemical device including the same. The gel polymer electrolyte includes: a multi-element cross-linking polymer matrix; a disassociable salt; and an organic solvent. The multi-element cross-linking polymer matrix has a content of 1 to 50 wt%. The multi-element cross-linking polymer matrix has a network structure that is formed by at least three different types of monomers which are capable of cross-linking being coupled by cross-linking. Each of the monomers capable of cross-linking includes at least one functional group selected from the group consisting of a carboxylic group, an acrylate group, and a cyano group.
