MoO3-doped V2O5 thin films electrode exhibit much enhanced electrochemical performances than the pure V2O5 counterpart. 1M nonaqueous solution of LiClO4 in propylene carbonate (PC) was the electrolyte solution about cyclic voltammetry (CV) of V2O5/MoO3/ITO glass electrodes at room temperature. With the increasing proportion of MoO3 doped in V2O5, all the redox peak currents of the five samples increased, suggesting that their electrochemical activity increased with the initial CV cycles. Disappearing of some phase transition peaks also show that the MoO3-doped V2O5 film makes cyclic stability declining. Compared with the switching speed of films, the coloring and the bleaching times of the MoO3-doped V2O5 thin films are shorter.
