Sr₂NiO₄ is a layered perovskite ceramic compound composed of strontium, nickel, and oxygen, belonging to the family of transition metal oxides with K₂NiF₄-type crystal structure. This material is primarily investigated in electrochemistry and solid-state ionics research, particularly for applications requiring mixed ionic-electronic conductivity at intermediate to high temperatures. It is notable as a cathode material candidate for solid oxide fuel cells (SOFCs) and oxygen transport membranes, where its layered structure facilitates ion migration while maintaining electronic conductivity.
