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 8.4 × 10 S cm were achieved at 323 K in (NH)(MgLi)F and NH(MgLi)F, respectively. It is implied that the molecular cation in the host lattice can assist the anion conduction. Our findings suggest molecular cation-containing compounds can be attractive material groups for fast anion conductors.
