Electric conductivity of gel-polymeric electrolytes with Ca, Mg and Zn perchlorate salts

Abstract

The gel-polymeric electrolytes were prepared with calcium, magnesium and zinc perchlorates dissolved in propylene carbonate together with poly (acrylo nitrile) or poly(methyl methacrylate) as a solution immobilizing polymers. The electric conductivity of these electrolytes was examined in the dependence of temperature and solvent content, at a constant salt-to-polymer concentration ratio. The electrolyte compositions were outlined having the conductivity close to 10 3 S cm 1. It was demonstrated that among the factors determining the conductivity, the cation nature plays a minor role, while the dominant role plays a liquid solvent (propylene carbonate) concentration.
