The nanocomposite films have possible application as templated nanocomposite cathodes for lithium rechargeable batteries. In this study, films consisting of a vanadium pentoxide phase formed within a rubbery block copolymer were developed towards nanocomposite cathodes for lithium rechargeable batteries. Nanocomposite films were prepared by sol-gel synthesis from vanadyl triisopropoxide precursor in poly(oligooxyethylene methacrylate)-block-poly(butyl methacrylate), POEM-b-PBMA. The in situ growth of amorphous V2O5 was confirmed by WAXS, XPS and SAXS. STEM and DSC demonstrated the selective incorporation of vanadium oxide within the ion-conducting POEM domains, while the oxide morphology was revealed by TEM to be a filamentous network. Templated nanocomposite films incorporating up to 34 wt% vanadium oxide were flexible and semi-transparent. |
