Abstract

V₂O₅·0.6H₂O nanoribbons were prepared and their electrochemical behaviors in K₂SO₄ aqueous solution were investigated. Results show for the first time that K⁺ ions could intercalate/deintercalate reversibly in the V₂O₅·0.6H₂O lattice. An asymmetric supercapacitor activated carbon/0.5 mol/l K₂SO₄/V₂O₅·0.6H₂O was successfully assembled, which could be cycled reversibly in the voltage region of 0-1.8 V. This supercapacitor presents an energy density of 29.0 Wh/kg based on the total mass of the active electrode materials, a very good rate behavior with energy density of 20.3 Wh/kg at power density of 2 kW/kg, and also a rather good cycling performance.
