Abstract
A polymer electrolyte having improved reliability and safety by increasing thermal stability of a polymer of the polymer electrolyte and crosslinking density of a matrix of the polymer while improving electrode impregnation capability by inducing low viscosity in a pre-gel composition, and a lithium rechargeable battery including the same are disclosed. The polymer electrolyte is a cured product of a polymer electrolyte composition including a lithium salt, a non-aqueous organic solvent, and a pre-gel composition including a first monomer represented by Chemical Formula 1, a second monomer represented by Chemical Formula 2 and a third monomer represented by Chemical Formula 3.
