Single-ion conductor nanocomposite organic-inorganic hybrid membranes for lithium batteries

A modified sol-gel synthesis of di-urethanosil resins provides an easy preparation of single-ion conductor membranes, by combining in one pot the in situ formation of oligosilsesquioxane nanofillers, the cross-linking of PEO chains and the covalent grafting of anion groups. Prototypal membranes demonstrated promising combination of thermal stability, flexibility and lithium ion conductivity performance.
