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⋅h⋅g⁻¹ at 0.3 A⋅g⁻¹, improved C-rate capability (274 mA⋅h⋅g⁻¹ and 102 mA⋅h⋅g⁻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).
