Abstract

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 (D_Li) of the V₂O₅ aerogel film was 9.18×10^-14cm²/s and exchange current was 12.5×10^-6A at potential step 3.6~3.5V_Li/Li+.
