Access to metastable complex ion conductors via mechanosynthesis: preparation, microstructure and conductivity of (Ba,Sr)LiF3 with inverse perovskite structure

“…In contrast, if SrF 2 is absent, the formation of BaLiF 3 by highenergy ball milling of LiF together with BaF 2 is clearly finished after 3 h. 49 The NMR signal attributed to F in the neighbourhood of a [Sr] 2 [Ba] 2 configuration appears at (d iso (SrF 2 ) + d iso (BaF 2 ))/2. In agreement with Vegard's law the lattice constant a of Sr 0.5 Ba 0.5 F 2 turns out to be 0.60 nm.…”

“…1,2 To at least the same extent, many attempts have been undertaken focussing on the improvement of transport parameters of known ion conductors by, e.g. interface engineering.…”

“…For many years much effort has been spent on developing new ion conductors [1][2][3][4][5][6][7][8][9][10] being vital for the successful design of, for instance, high-energy batteries, 8,[11][12][13] fuel cells, 1,2,13 electrochromic devices, 1,2,13 and sensors. 1,2 To at least the same extent, many attempts have been undertaken focussing on the improvement of transport parameters of known ion conductors by, e.g.…”

A Supramolecular Double Sulfate Salt with a Lamellar Type: Crystal Structure and Thermal Behavior

“…Lamellar materials are of huge importance in the host–guest chemistry, due to their essential role in intercalation/deintercalation processes, which makes them useful in adsorption, electronic/ionic conduction, and catalysis reactions, for example. − They include a large variety of materials, from clays, chalcogenides, oxides and oxoanion-based compounds, layered double hydroxides, graphene-based structures, organically pillared clays, or two-dimensional (2D) coordination polymers . They may be pure inorganic, hybrid organic–inorganic, or metal–organic compounds.…”

Inorganic layered structures in hybrid double sulfates: related phases and thermal reactivity

“…[16][17][18] The lamellar materials have great importance in intercalation and deintercalation processes which make them very useful in the field of adsorption, ionic and electronic conduction and the catalytic reactions. [19][20][21] They include a wide variety of materials such as clays, 22,23 chalcogenides, 24 oxides and oxo-anion based compounds, 25 the layered double hydroxides, 26 graphene 27 and two-dimensional polymer coordination. 28 Their thermal stability gives them an interesting property to cover other potential applications.…”
