Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201403157-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Na₂B₁₀H₁₀</bold> 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‐centered‐cubic 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. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh2hmvnvd2" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
