Beschreibung
Zusammenfassung:	A polymeric gel electrolyte and a lithium battery employing the same are disclosed. The polymeric gel electrolyte includes a first ionic conductive polymer having a weight-average molecular weight of greater than or equal to 5,000 and smaller than 100,000, a second ionic conductive polymer having a weight-average molecular weight of 100,000 to 5,000,000, and an electrolytic solution that includes a lithium salt and an organic solvent. The first ionic conductive polymer preferably is at least one polymer selected from polyethyleneglycol dimethylether, polyethyleneglycol diethylether, polyethyleneglycol dimethacrylate, polyethyleneglycol diacrylate, polypropyleneglycol dimethacrylate, polypropyleneglycol diacrylate, and mixtures and combinations thereof, and the second ionic conductive polymer preferably is at least one polymer selected from polyvinylidenefluoride, polyvinylidenefluoride-hexafluoropropylene copolymer, polyurethane, polyethylene oxide, polyacrylonitrile, polymethylmethacrylate, polyacrylamide, polyacetate, and mixtures and combinations thereof.
