Investigating the Factors Affecting the Ionic Conduction in Nanoconfined NaBH4

Nanoconfinement is an effective strategy to tune the properties of metal hydrides. It has been extensively employed modify ionic conductivity LiBH4 as electrolyte for Li-ion batteries. However, approach does not seem be applicable other borohydrides such NaBH4, which found reach a limited improvement in 10−7 S cm−1 at 115 °C upon nanoconfinement Mobil Composition Matter No. 41 (MCM-41) instead 10−8 cm−1. In comparison, introducing large cage anions form Na2B12H12 naturally formed NaBH4 was more leading higher conductivities 10−4 110 °C.
