Na-2(B12H12) (0.5)(B10H10) (0.5), a new solid-state sodium electrolyte is shown to offer high Na+ conductivity of 0.9 mS cm(-1) at 20 degrees C, excellent thermal stability up to 300 degrees C, and a large electrochemical stability window of 3 V including stability towards sodium metal anodes, all essential prerequisites for a stable room-temperature 3 V all-solid-state sodium-ion battery.
