Abstract

To determine the mechanism responsible for the formation of electrolytic sodium-vanadium oxide bronze 6-Na_xV₂O₅, synthesized earlier from acid vanadyl sulfate electrolyte, β-bronze i-Na_xV₂O₅ is synthesized by exposing electrolytic oxide e-V₂O₅ in the same sodium-containing electrolyte under open-circuit conditions, with a subsequent annealing of the sample. It is established that the two modifications of β-bronze (e-Na_xV₂O₅ and i-Na_xV₂O₅) are identical and that electrolytic precursors of β-bronze Na_xV₂O₅ form via an ion-exchange mechanism.
