Single-Ion Conduction and Electrochemical Characteristics of Poly (Oxyethylene)/ Lithium Methoxy Oligo(Oxyethylene) Sulfate Blend

The ion conduction of a blend of poly(oxyethylene) (PEO) and lithium methoxy oligo(oxyethylene) sulfate (SAL8) and its electrochemical characteristics were studied. The maximum ambient conductivity...

Single Ion Conduction in Lithium Methoxy Oligo(Oxyethylene) Sulfate-Comblike Polyether Complex

Abstract Two kinds of lithium methoxy oligo(oxyethylene) sulfate (LiSAEO8 and LiSAEO12) were synthesized, and their complexes were prepared with poly[methoxy oligo(oxyethylene) methacrylate-co-acrylamide] [P(MEO16-AM)]. Both the crystallinity and the glass transition temperature of the complexes decrease with increasing salt concentration. P(MEO16-AM)/LiSAEO8 and P(MEO16-AM)/LiSAEO12 exhibit single ion conduction characteristics, and their ionic conductivities at 25°C are 1.4 × 10−5 and 7.7 × 10−6 S/cm, respectively.
