Abstract
The teachings herein relate to a gel polymer electrolyte, manufacturing of a gel polymer electrolyte, and an electrochemical device including the gel polymer electrolyte. The present gel polymer electrolyte preferably includes a multi-component crosslinked polymer matrix; a dissociable salt; and an organic solvent. The content of the multi-component crosslinked polymer matrix preferably is 1 to 50 weight percent and preferably has a net structure formed by crosslinking at least three different kinds of cross-linkable monomers. Each of the cross-linkable monomers preferably includes at least two of the following functional groups: a carboxylic group, an acrylate group, or a cyano group. The method of manufacturing the gel polymer electrolyte preferably uses a thermal crosslinking or photo-crosslinking process.
