| Abstract: | Poly ethylene oxide(PEO) x-V 2O 5-MoO 3(x=0,0.5,1) films were prepared by the sol-gel method.The synthesis and structure of the films were investigated by XRD,TG-DTA,FTIR,etc.The results show that V 2O 5-MoO 3 xerogel has a layered structure and its interlayer space increased from 1.3181nm at x=0 to 1.7898nm at x=1 after the nanocomposite films were dried,and PEO in the interlayer changes the interface structure by forming hydrogen bonds with V=O bands.CV measurement indicates that the intercalation of PEO improves insertion/extration properties of Li+ ions in the interlayer. |
