Popis:	Five novel lithium polyelectrolyte-ionic liquid systems, using poly (lithium 2-acrylamido-2-methyl propanesulfonate; PAMPSLi) were prepared and their electrochemical properties were measured. The ionic conductivity of the PAMPSLi/1-ethyl-3-methylimidazolium tricyano methanide (emImTCM) system was exhibited high conductivity (1.28 × 10−3 S/cm−1). The high conductivity and low viscosity of PAMPSLi/emImTCM system is due to the high flexibility of imidazolium cation and dissociation of lithium cation from the polymer chains. The PAMPSLi/N,N-dimethyl-N-propyl-Nbutylammonium tricyanomethanide (N1134TCM) and PAMPSLi/N, N-dimethyl-N-propyl-N-butylammonium dicyanamide (N1134DCA) systems showed fairly high conductivity (6.3 × 10 −4 S/cm−1, 6.0 × 10−4 S/cm−1). PAMPSLi/Trihexyl (tetradecyl) phosphonium bis (trifluoromethane sulfonyl) amide (P66614TFSA) exhibited low conductivity (2.22 × 10 −5 Scm−1) and thermally stable over 400C.
