Pervanadyl (V O+2) is a pale yellow^[1] oxycation of vanadium(V). It is the predominant vanadium(V) species in acidic solutions with pH between 0 and 2, and its salts are formed by protonation of vanadium(V) oxide in such solutions:^[2]^[3]

V₂O₅ + 2 H⁺ → 2 VO+2 + H₂O (K = 3.42×10⁻²)

The ion can form a complex with a single aminopolycarboxylate ligand,^[4] or with tridentate Schiff base ligands.^[5]

The VO+2/VO²⁺ redox couple is used at the cathode of the vanadium redox battery.^[6] The standard reduction potential of this couple is +1.00 V.^[7]
