Abstract

Investigation of intergrowth structures consisting of perovskite blocks alternating with other blocks along the c-axis has been found to offer a novel "doping strategy" for fast oxide-ion conduction at significantly lower temperatures. Barium indium oxides such as Ba₃In₂MO₈ (M = Zr, Hf and Ce) have an intergrowth structure in which two octahedral layers alternate with one tetrahedral layer along the c-axis. These oxides exhibit remarkable O^2--ion conduction at 400°C with a low activation energy E_a≲0.6eV. A variety of substitution on the vanadium site in Bi₄V_2-yM_yO_11-δ has led to the identification of fast O^2-- ion conduction at y≈0.2 for M = Ti and Nb in addition to that found with M = Cu by French group. Observation of fast oxide-ion conduction at T<400°C brings renewed interest to the field of oxide-ion electrolytes.
