Mixed conductor

Cerium oxide is a potent mixed conductor.[1]

Mixed conductor which is known as mixed ion-electron conductor (MIEC) refers to a single phase material which has a significant conduction ionically and electronically.[1][2][3] Due to the mixed conduction, a formally neutral species can transport in a solid and therefore mass storage and redistribution are enabled. Mixed conductors are well known in conjugation with High-temperature superconductivity and are able to capacitate rapid solid-state reactions. They are used as catalysts (for oxidation), permeation membranes, sensors and electrode in batteries since they allow for rapidly transducing chemical signals and permeating chemical components.[3] Strontium titanate (SrTiO3), Titanium oxide (TiO2), (La,Ba,Sr)(Mn,Fe,Co)O3-d, La2CuO4+d, Cerium(IV) oxide (CeO2), Lithium iron phosphate (LiFePO4) and LiMnPO4 are the examples for the mixed conductors.[1]
