La0.98Sr0.02CoO3 is a rare-earth doped perovskite ceramic composed primarily of lanthanum cobaltite with strontium substitution. This material is primarily investigated in electrochemistry and materials research for solid-state energy applications, where its mixed ionic-electronic conductivity makes it relevant for oxygen reduction catalysis and electrochemical devices. The strontium doping modifies the electronic structure and defect chemistry compared to undoped lanthanum cobaltite, making it of particular interest for fuel cells, oxygen permeation membranes, and catalytic applications where thermal stability and ionic transport are critical.
