One-Pot Production of Gel Polymer Electrolyte for Fabrication of Lithium-Ion Batteries

This study presents the preparation of a gel polymer electrolyte (GPE) based on ethylene oxide forlithium-ion battery. Initially, two monomers, poly(ethylene glycol) methacrylate (PEGMA) andglycidyl methacrylate (GMA), were dissolved in an appropriate carbonated solvent and lithium saltmixture, followed by polymerization through the radical polymerization method to achieve thedesired polymer electrolyte gel. The structure of the gel was characterized using FT-IR spectroscopy.Furthermore, the electrochemical properties assessed by electrochemical impedance spectroscopy(EIS) testing indicated that the gel with its intrinsic resistance of ۲۳۷ moh and other beneficialelectrochemical characteristics such as the zero kinetic resistance, has potential for batteryapplications.
