Vanadium(V) oxide was coated by poly(3,4-ethylenedioxythiophene) (PEDOT) by chemical oxidation of EDOT. The obtained composite (V2O5/PEDOT) was studied as cathode material for aqueous zinc-ion batteries. V2O5/PEDOT electrodes demonstrate excellent electrochemical performance in the (0.3-1.4) V (vs. Zn/Zn2+) potential range in comparison to electrodes based on the pristine V2O5. V2O5/PEDOT material provides high specific capacity 380 mA.Mg-1 at 0.3 16 A.g(-1), improved C-rate capability (274 mA.Mg-1 and 102 mA.Mg-1 at 5 A.g(-1) and 20 A.g(-1), and better stability during long-term cycling (7% capacity fading during 200 cycles at 5 A.g(-1)).
