Abstract

The present invention relates to a composition for a gel polymer electrolyte and a gel polymer electrolyte prepared using the same, and specifically provides a composition for a gel polymer electrolyte including a lithium salt, an organic solvent, and a polymer A having an epoxy group represented by Formula 1, and a polymer B having an amine group and a cyanide group represented by Formula 2, wherein the polymers A and B are included in an amount of 1 to 20 wt % based on the total weight of the composition for a gel polymer electrolyte, and wherein a gel polymer electrolyte for a secondary battery can be prepared that includes a polymer network formed by combining the polymer A having an epoxy group represented by Formula 1 and the polymer B having an amine group and a cyanide group represented by Formula 2 in a three-dimensional structure.
