Abstract
Impedance measurements indicate that Na2B12H12 exhibits dramatic Na(+) conductivity (on the order of 0.1 S cm(-1)) above its order-disorder phase-transition at ≈529 K, rivaling that of current, solid-state, ceramic-based, Na-battery electrolytes. Superionicity may be aided by the large size, quasispherical shape, and high rotational mobility of the B12H12(2-) anions.
摘要
阻抗测量表明，Na2B12H12 在其有序-无序相变温度（约 529 K）以上表现出显著的 Na(+)导电性（约 0.1 S cm(-1)），可与目前基于固态陶瓷的 Na 电池电解质相媲美。B12H12(2-)阴离子的大尺寸、类球形形状和高旋转迁移率可能有助于超离子导电性。
