Mixed conductor

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. 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. Strontium titanate (SrTiO₃), Titanium oxide (TiO₂), (La,Ba, Sr)(Mn,Fe,Co)O_3−d, La2CuO_4+d, Cerium(IV) oxide (CeO₂), Lithium iron phosphate (LiFePO₄) and LiMnPO₄ are the examples for the mixed conductors.
