Ionic conductors in the systems (Sb,Bi,Te)-(Mo,V,Nb)-O: syntheses,structures, and properties

Ionic conductors are of tremendous importance for numerous and various applications from the fields of batteries up to sensors. The aim was to enlarge their potentialities by creating new families of compounds having such properties. Our researches have been focused on oxides containing both M transition elements (M equals Mo, V, Nb) and `lone pair oxides', i.e. from M* elements like M* equals Sb III, Te IV, Bi III, characterized by a ns2 electronic state involving a lone pair E of electrons. Some new compounds will be presented and their particular atomic structures depicted.
