The key components of GPEs include: - Polymer Matrix: Provides structural integrity and mechanical stability. Common polymers used include poly(ethylene oxide) (PEO), poly(acrylonitrile) (PAN), and poly(vinylidene fluoride) (PVDF). - Liquid Electrolyte: Imparts ionic conductivity to the polymer matrix. It typically consists of a solvent like ethylene carbonate or propylene carbonate, and a salt such as lithium perchlorate (LiClO4) or lithium bis(trifluoromethanesulfonyl)imide (LiTFSI). - Plasticizers: Enhance the flexibility and ionic conductivity of the GPE by reducing the glass transition temperature of the polymer.
