Sr2LaMn2O7

Sr2LaMn2O7 is a layered perovskite ceramic compound composed of strontium, lanthanum, and manganese oxides, representing a class of materials studied for their mixed ionic-electronic conducting properties. This material is primarily investigated in research contexts for energy conversion and storage applications, particularly as a cathode material or oxygen transport membrane, where its ability to conduct both ions and electrons at elevated temperatures offers advantages over conventional ceramic oxides. Its layered crystalline structure and variable oxidation states make it a candidate for next-generation solid oxide fuel cells and oxygen separation membranes, though it remains largely in the development phase rather than in widespread industrial production.
