Abstract
Na2B10H10 exhibits exceptional superionic conductivity above ca. 360 K (e.g., ca. 0.01 S cm-1 at 383 K) concomitant with its transition from an ordered monoclinic structure to a face-centeredcubic arrangement of orientationally disordered B10H102- anions harboring a vacancy-rich Na+ cation sublattice. This discovery represents a major advancement for solid-state Na+ fast-ion conduction at technologically relevant device temperatures. (Graph Presented).
