Fast fluoride ion conduction of NH(MgLi)F and (NH)(MgLi)F assisted by molecular cations.

Aiming development of the fast anion conductors, we proposed a new material design using flexible molecular cation as a host cation, and demonstrated it with fluoride ion conduction in NHMgF and (NH)MgF based materials. Dominant fluoride ion conduction with relatively high conductivities of 4.8 × 10 S cm and 8.
