✦ Synopsis

The single-Li+ conduction of the cross-linking poly [ oligo (oxyethylene) methacrylate-colithium methacryloyl hexylsulfonate 1s was studied, and an Li+ ionic transport number of 0.994 estimated from the isothermal transient ionic current (ITIC) , in which an ion-blocking platinum electrode was used. The results show that Li+-ionic conduction can be reasonably described by Vogel-Tammann-Fulcher ( VTF ) equation, suggesting that there is close correlation between ionic migration and segmental motion in these polymers. The battery composed of lithium/ this copolymer film/polyaniline supplied a constant short circuit current ( J s c ) of 45 pA/cm2 and an open circuit potential (V,) of 3.6 V at 25°C.
