Poly(ethylene oxide)‐based composite gel polymer electrolytes (CGPE's) were prepared for various concentrations of magnesium aluminate (MgAl 2 O 4 ) 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. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.
