We have studied sodium-ion conduction in complex hydrides NaAlH 4 and Na 3AlH 6. The electrical conductivities of these complex hydrides were studied using ac impedance measurements at temperatures up to 363 K for NaAlH 4 and 433 K for Na 3AlH 6. Nyquist plots obtained by the measurements indicated the sodium-ion conduction. Also, dc measurements showed that sodium-ion transference numbers of NaAlH 4 and Na 3AlH 6 were almost unity. Na 3AlH 6 exhibited the sodium-ion conduction of 4.1 × 10 -4 S/cm at 433 K. This study will open up research on complex hydrides as solid-state sodium-ion conductors.
