Abstract :
Bi-ionic oxide bronzes of the AxBOy type (A=Na, Ca, Na–Ca, Sr, Na–Sr; B=V) were synthesized by solid state method. The values of partial electronic conductivity in the zNa0.33V2O5–(1−z)Ca(Sr)0.165V2O5 systems and ionic reversibility at the zNa0.33V2O5–(1−z)Sr0.165V2O5/Na3Zr2Si2PO12 interface were determined as functions of Na0.33V2O5 content. It has been found that the ion substitution process Sr2+⇔2Na+ occurs at the Sr0.165V2O5/Na+-SE interface.
