Fig.6 Unit cells of the (a) low-temperature ordered monoclinic and (b) high-temperature disordered cubicNa2B12H12 structures viewed along the c-axes. Yellow, purple, and white spheres represent Na, B, and H, respectively[107]; (c) comparison of ionic conductivities for pristine vs. ball-milled Na2B12H12[112]; (d) linear sweep voltammetry from 1.3 to -0.1 V and 2.0 to 4.0 V (vs. Na/Na+) with a scan rate of 0.05 mV/s at 60 oC. (the linear fitted lines are shown by black dashed lines)[116]
