| abstract |
The present invention relates to a composition for a gel polymer electrolyte and a gel polymer electrolyte prepared therefrom, specifically, a lithium salt, an organic solvent, a polymer A comprising an epoxy group represented by the formula (1) and an amine group represented by Formula 2 and cyanide A polymer B comprising a group, wherein the polymers A and B are represented by Chemical Formula 1 by providing a composition for gel polymer electrolyte that is contained in an amount of 1 wt% to 20 wt% based on the total weight of the gel polymer electrolyte composition. A polymer A including an epoxy group, and a polymer B including an amine group represented by Formula 2 and a polymer B including a cyanide group are bonded in a three-dimensional structure to prepare a gel polymer electrolyte for a secondary battery. |
