Good electrode materials play an important part in rechargeable Li batteries. In this paper, safe and inexpensive
vanadium pentoxide (V2O5) aerogel materials were used as cathode materials. We discussed preparation of the films and
lithium ion diffusion at the interface between the cathode and electrolyte by potential-step current transient technique and
digital simulations. The results showed that diffusion coefficient (DLi) of the V2O5 aerogel film was 9.18×10-14cm2/s and
exchange current was 12.5×10-6A at potential step 3.6~3.5VLi/Li+.
