New lithium conducting polymer electrolytes for power sources

The main roads of development in industrially useful solid polymer electrolytes (SPEs) are briefly reviewed. New SPEs based on acrylonitrile copolymers PBAN and PAN and lithium salts LiAsF₆, LiCF₃SO₃, LiCIO₄ have been obtained. The limits of salts solubility in polymer matrix PBAN were established. Ion solvation and ion association processes have been studied by 1R spectroscopy. Conducting properties of SPEs were measured at 20-100°C. The existence of different ion transport mechanisms corresponding to different salt concentration regions are discussed.
