文摘

Amorphous vanadium oxide/carbon composite (V₂O₅/C) was first applied to the positive electrode active material for rechargeable aluminum batteries. Electrochemical properties of V₂O₅/C were investigated by cyclic voltammetry and charge鈥揹ischarge tests. Reversible reduction/oxidation peaks were observed for the V₂O₅/C electrode and the rechargeable aluminum cell showed the maximum discharge capacity over 200 mAh g^鈥? in the first discharging. The XPS analyses after discharging and the following charging exhibited that the redox of vanadium ion in the V₂O₅/C active material occurred during discharging and charging, and the average valence of V changed between 4.14 and 4.85.
