   Abstract:
   We have prepared Ag-Ag 0.08V 2O 5· nH 2O composite films by dispersing Ag nanowires into V 2O 5·nH 2O sol and have investigated electrochemical properties of the films for Li ⁺-ion intercalation applications. With the molar ratio of Ag nanowires to V 2O 5·nH 2O as 0.1, such prepared films are composed of metallic Ag nanowires embedded in the matrix of Ag 0.08V 2O 5·nH 2O, due to partial Ag reacted with V 2O 5·nH 2O. At a current density of 85 mA/g, such Ag-Ag 0.08V 2O 5·nH 2O film can intercalate about two equivalents of Li ions and delivers twice the capacity of the V 2O 5·nH 2O xerogel film. Such improved electrochemical performance is ascribed to the changes in the microstructure and crystallinity of the Ag-Ag 0.08V 2O 3·nH 2O films including (i) further amorphization of V 2O 3·nH 2O, (ii) increased porosity, and (iii) enhancement of electrical conductivity. © 2005 WILEY-VCH Verlag GmbH & Co.
