Electrochemical Properties of Polyethylene Oxide ‐ Li [ ( CF 3 SO 2 ) 2 N ] ‐ Gamma ‐ LiAlO2 Composite Polymer Electrolytes

Abstract
The electrochemical properties of polymer electrolytes based on polyethylene oxide (PEO) and , with and without the addition of dispersed powder, are reported. The results clearly indicate that the use of the ceramic filler combined with the salt greatly reduces the crystallization rate and enhances the lithium/electrolyte interface stability.
