Abstract

Conductivity, transport and interfacial studies on an amorphous methoxy-linked poly(ethylene oxide)/Zn(CF3SO3)2 System over the O:Zn range 100:1 to 10:1 are reported. A passivating layer on the zinc electrode has been studied and a convenient technique of electrochemical polishing has been devised to reduce its impedance. Standard ac conductivity and DSC studies have been supplemented by dc polarization measurements using the symmetric cell Zn\polymer electrolyte\Zn. Preliminary results of transference number determination using the Hittorf method suggest that transport of zinc in a concentration gradient is augmented by motion of neutral ionic complexes.
