A Comparative Review of Characterization of Polymer Electrolytes for Energy Storage Application

Abstract

In this review article, the recent progress in poly (ethylene oxide) based polymer electrolytes are comparatively studied based on the characterization of the poly(ethylene oxide) for its application in energy storage devices. Requirements for the polymer host, salt, solvent, nanofiller, and ionic liquid are elaborated in detail followed by the comparison of polymer electrolytes obtained by complexation of silver trifluoromethane sulfonate [AgCF 3 SO 3 ] (also known as silver triflate) with PEO and PEO blend of Lithium trifluoromethanesulfonate with linear formula CF 3 SO 3 Li based on influence of addition of additives to improve electrical conductivity and crystallinity of the PEO matrix.
