摘要

Poly(ethylene oxide)-based composite gel polymer electrolytes (CGPE's) were prepared for various concentrations of magnesium aluminate (MgAl2O4) and LiTFSI as salt with a combination of 1,3-dioxolane (DOL) and tetraethylene glycol dimethyl ether (TEGDME) as plasticizer by a simple solution casting technique. The addition of plasticizers has significantly improved the ionic conductivity of the gel electrolytes. The prepared CGPEs were subjected to scanning electron microscopy, thermal, and FT-IR analysis. The electrochemical properties such as ionic conductivity, compatibility, and charge-discharge behavior have also been studied. Preliminary studies revealed that the prepared CGPE can be employed as a potential electrolyte for lithium-sulfur (Li-S) batteries. (C) 2016 Wiley Periodicals, Inc.
