Sr-anchoring-directed gradient shell architecture in Sr 2 Fe 1.5 Mo 0.5 O 6- δ cathodes for reversible protonic ceramic electrochemical cells

Abstract Strontium segregation remains a critical challenge for Sr-containing double perovskite cathodes, wherein outward-migrating Sr species accumulate at the surface and severely deteriorate interfacial electrochemical kinetics in reversible protonic ceramic electrochemical ce...
