Analysis of the frequency dispersion together with conductivity and transference number determinations have been performed for the cells Ni\(PEO)(x)NiCl2\Ni, Ni\(PEO)(x) NiI2\Ni, Zn\(PEO)(x)ZnCl2\Zn and Zn\(PEO)(x)ZnI2\Zn with x varying between 4 and 20. The electrolytes were obtained using solvent casting as a preparation method. Working temperatures between 20 and 155 degrees C rendered conductivity values ranging from 10(-9) to 5 X 10(-4) S cm(-1). It has been shown that the nickel-containing samples are mainly anionic polymer electrolytes while those containing zinc are essentially mixed ionic conductors. Fitting based on nonlinear least-squares allowed the building of equivalent circuits to obtain parameters associated to low frequency data.
