· JVASP-11667· Sr2Mn2O5

Sr2Mn2O5 is a strontium-manganese oxide ceramic compound belonging to the perovskite-related oxide family, primarily investigated for electrochemical and energy conversion applications. This material is of research interest for solid oxide fuel cells (SOFCs), oxygen separation membranes, and catalytic systems where mixed-valence manganese oxides provide enhanced ionic and electronic conductivity. While not yet widely commercialized in high-volume applications, Sr2Mn2O5 and related strontium manganate compounds are promising alternatives to conventional SOFC cathode materials due to their potential for improved oxygen reduction kinetics and thermal compatibility with electrolyte materials.
