Fast fluoride ion conduction of NH(4)(Mg(1-x)Li(x))F(3-x) and (NH(4))(2)(Mg(1-x)Li(x))F(4-x) 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 NH(4)MgF(3) and (NH(4))(2)MgF(4) based materials. Dominant fluoride ion conduction with relatively high conductivit...

description 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 NH(4)MgF(3) and (NH(4))(2)MgF(4) based materials. Dominant fluoride ion conduction with relatively high conductivities of 4.8 × 10(–5) S cm(−1) and 8.4 × 10(–6) S cm(−1) were achieved at 323 K in (NH(4))(2)(Mg(0.85)Li(0.15))F(3.85) and NH(4)(Mg(0.9)Li(0.1))F(2.9), 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.
