Abstract

The effects of platinum doping on the structural and electrochemical properties of amorphous vanadium pentaoxide (V2O5) films grown by radio frequency (rf) magnetron sputtering were studied. The cycling behavior was gradually degraded with increasing platinum content. The short range ordered structure reappeared when the films were doped by cosputtering at rf powers of 30 and 50 W. It was shown that doping at a rf power of 50 W results in the formation of amorphous and nanocrystalline PtO5 phases embedded in the V2O5 matrix.
