solid polymer electrolytes

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 IR spectroscopy. Conducting properties of SPEs were measured at 20-100°C.

Polymer Electrolytes for Sodium-ion Batteries


The critical analysis of literature of last 15 years, concerning solid polymer electrolytes with Na+-ion-conductivity is presented. True polymer electrolytes as well as gel-polymer electrolytes based on polyethylene oxide, polyacrylonitrile, polyvinyl alcohol, polyvinyl chloride, polyvinyl pyrrolidone, PVdF–HFP, PMMA, Nafion are reviewed. Special attention is paid for temperature dependence of conductivity.
