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.
