La2NiO4 is a layered perovskite ceramic compound composed of lanthanum, nickel, and oxygen, belonging to the Ruddlesden-Popper family of oxides. This material is primarily investigated for electrochemical and thermal applications, particularly as a cathode material in solid oxide fuel cells (SOFCs) and as an oxygen ion conductor in intermediate-temperature electrochemical devices. Its mixed ionic-electronic conducting properties and structural stability make it an attractive alternative to conventional cathode materials, with ongoing research focused on optimizing its electrochemical performance and sintering behavior for commercial energy conversion applications.
