Description
`Solid state compounds with ionic conductivity larger than 1 mS/cm at room temperature can compete with liquid electrolytes when applied in rechargeable batteries. Recently new sulfide materials with this property were discovered, extending family of ionic conductors based on oxides.`
`Very high conductivity of sodium reported in Na$_2$B$_{12}$H$_{12}$ competes with the best solid state conductors known for this metal. Further developments brought borane based Na superionic conductors that are by orders of magnitude better than those based on $\beta$-alumina.`
`We will present theoretical study, based on DFT calculations, explaining the conductivity mechanism in closo-borates, as well as pointing out the differences in conductivity of lithium and sodium.`
