Abstract
The polymer electrolyte PEO + AgNO3 has been investigated by IR, optic al absorption, DTA, electrical conductivity, mobility, and transport n umber measurements. The material is a mixed (ionic + electronic) condu ctor. The ionic conductivity is due to Ag+ and anionic movement. The m aterial properties change with time, mainly associated with an increas ed electronic conductivity due to reduction of Ag+ in PEO lattice. The maximum electrical conductivity has been found to be approximate to 3 X 10(-7) s cm(-1) for the composition Ag+/EO=0.014 to 0.085.
