PURPOSE: Provided is a polymer electrolyte for a lithium secondary battery, which is excellent in ion-conductivity, processability, electric insulation ability, and mechanical property. CONSTITUTION: The polymer electrolyte comprises a polymer matrix, an ionic inorganic salt, and a solvent, wherein the polymer matrix comprises a vulcanized polymer containing 1-15wt% of sulfur. The vulcanized polymer is produced by reacting the sulfur with a polymer selected from the group consisting of polybutadiene, polyisobutylene, polyisoprene, polybutyl rubber, polyacrylate, and polymethylacrylate. And the polymer electrolyte is coated on both sides of a separator. |
