Provided is a polymer electrolyte containing an ionic liquid, which has a uniform pore distribution, contains a large amount of an organic electrolyte and an ionic liquid, and shows excellent ion conductivity and electrochemical stability. The polymer electrolyte containing an ionic liquid comprises a polymer film obtained by spin-coating a mixed solution containing a polymer and a solvent via a phase transition process, wherein the polymer film is impregnated with an organic electrolyte comprising an ionic liquid and a lithium salt. The polymer film is obtained by using a mixed solution comprising 10-40 wt% of the polymer and 60-90 wt% of the solvent. The organic electrolyte contains at least one carbonate solvent. The ionic liquid includes 1-butyl-3-methylimidazolium tetrafluoroborate. |
