Abstract
The present invention discloses a copolymer for a polymer electrolyte, and a gel polymer electrolyte and a lithium secondary battery which include the same. Specifically, the present invention discloses a copolymer for a polymer electrolyte, which includes a fluorine-based polymer main chain and a unit derived from an acrylate-based monomer or an acrylate-based polymer containing an ion conductive functional group grafted to the fluorine-based polymer main chain, and a gel polymer electrolyte in which lithium ion transfer capability is improved by including the same. Also, the present invention may prepare a lithium secondary battery with enhanced high-temperature safety by including the gel polymer electrolyte.
