Gel polymer electrolyte, electrochemical device, and methods thereof

A gel polymer electrolyte comprising:

• a multi-component crosslinked polymer matrix;
• a dissociable salt;
• and
• an organic solvent,
• wherein a content of the multi-component crosslinked polymer matrix is 1 to 50 wt %, and
• the multi-component crosslinked polymer matrix has a net structure formed by crosslinking at least three different kinds of crosslinkable monomers including a first monomer, a second monomer, and a third monomer,
• wherein each of the crosslinkable monomers includes any functional group selected from the group consisting of a carboxylic group, an acrylate group, and a cyano group;
• and
• the multi-component crosslinked polymer matrix includes the acrylate group, together with the carboxlic group or the cyano group;
• wherein the first monomer includes two or more functional groups which are each an acrylate group, and the second and third monomers are different from the first monomer in that they include a functional group different from an acrylate.
