Abstract: 

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 IR 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.

Key words: 
solid polymer electrolytes
polyacrylonitrile
ion transport
