A-site-deficiency range identified for in situ exsolution from (La0.4Sr0.6)1−αTi0.95Ni0.05O3±δ electrodes for SOFC and SOEC

A wide range of A-site-deficient samples of (La 0.4 Sr 0.6 ) 1− α Ti 0.95 Ni 0.05 O 3− δ ( α = 0.00, 0.13, 0.15, and 0.18) was designed to investigate their properties, exsolution process, and electrochemical performance.
