A Mechanism for the Fast Ionic Transport in Nanostructured Oxide-Ion Solid Electrolytes

摘要

Nanostructured materials have attracted great interest in recent years due to their new or enhanced properties, which have been exploited in very different applications. In several cases, however, the physical mechanisms responsible for these properties are not completely known yet. One important example is the enhancement of ionic conductivity in nanostructured solid electrolytes, which is discussed in the present work. In fact, nowadays "nanoionics" is one of the hottest fields of research related to nanomaterials, and several applications are being explored, e.g., rechargeable lithium-ion batteries, gas sensors, and solid-oxide fuel cells.
