Abstract

Na2B10h10 undergoes a transition from an ordered monoclinic phase to a disordered, face-centered-cubic phase near 370 K with the emergence of a vacancy-rich, mobile Na+ sublattice exhibiting dramatic superionicity ({approximately equal}0.01 S cm-1 at 383 K). This represents a major advancement for solid-state Na+ fast-ion conduction at lower temperatures.
